Networking How To Create And Configure VLANs In pfSense


pfSense is a customized version of FreeBSD tailored specifically for use as a perimeter firewall and router, managed entirely from a web browser or command line interface. pfSense includes a long list of other features, as well as a package system allowing its capabilities to be expanded even further. pfSense is free, open source software distributed under the BSD license.

A VLAN (“Virtual Local Area Network”) is a logical grouping of network hosts (and other resources) connected to administratively defined ports on a switch. This enables hosts to communicate as if the attached to the same physical medium, when in fact they may actually be located on different LAN segments. A VLAN is treated like its own subnet or broadcast domain, which means that Ethernet frames broadcast onto the network are only switched between the ports logically grouped within the same VLAN.

In this post I will describe how to create and configure VLANs in pfSense. Once configured, you’ll be able to route (or prevent routing) traffic between each VLAN, and each VLAN will be able to share the same Internet connection. To help explain the steps involved, we’ll create two static VLANs on a 24-port switch and trunk those VLANs from the switch to the LAN interface on pfSense, where we will assign each VLAN a unique /24 private IP subnet.

All steps involved assume that: 1) pfSense is installed correctly and providing basic Internet connectivity to an existing LAN interface; 2) the NIC (“Network Interface Controller”) assigned to the LAN interface supports IEEE 802.1Q VLAN tagging; and, 3) the switch connected to the LAN interface is capable of supporting the creation, configuration and trunking of port-based VLANs.

The software versions used in this post were as follows:

  • pfSense v2.1.2 (x32)
  • The switch used in this post was a Cisco model SG200-26; a so-called “smart switch,” featuring, among other things, Gigabit Ethernet, a web-based management interface, and simultaneous support for up to 256 port-based and IEEE 802.1Q tag-based VLANs.

    Each switch, and its associated management interface, however, is different; therefore, you’ll need to make the appropriate adjustments when following the instructions in this post in order to successfully configure your particular switch.

    Let’s get started…

    Configuring The Switch

    As you may recall, static VLANs, often referred to as “port-based” VLANs, are created by assigning switch ports to a preconfigured VLAN identifier. In our example, we’ll configure two static VLANs on our switch and assign them VLAN ID 10 and VLAN ID 20. Note that you can use any positive integer between 2 and 4094 you’d like for your VLAN ID, however, VLAN IDs 1 and 4095 should be avoided because, as a general rule, most switches by default assign all ports to VLAN ID 1, the “administrative” VLAN ID, and VLAN ID 4095 as the “discard” VLAN.

    Begin by navigating to VLAN Management->Create VLAN and select “Add.” Enter a value of 10 in the “VLAN ID” field and enter a name to denote this particular VLAN in the “VLAN Name” field. In this example, we’ve used the name “vlan10.” When complete, select “Apply”. (See Figure 1)

    Screenshot showing the creation of a new VLAN ID 10 in the Cisco SG200-26 switch

    Figure 1

    Perform the same steps to create the second VLAN, this time assigning a value of 20 to the “VLAN ID” field and “vlan20” to the “VLAN Name” field. When complete, select “Apply” and you should see the newly minted VLANs listed (See Figure 2).

    Screenshot showing that two VLANs have been created in the Cisco SG200-26 switch

    Figure 2

    Before assigning membership of a particular port to one of our new VLANs, we must first configure that port to be either an “Access” port or a “Trunk” port. Access ports are ports that are members of only one VLAN. This type of port is normally used for attaching end devices which are generally unaware of a VLAN membership, either because their NIC is incapable of tagging Ethernet frames a VLAN ID, or they are not configured to do so. Switch ports configured as Access ports remove any VLAN information from the Ethernet frame before it is sent to the device. Trunk ports on the other hand can carry multiple VLAN traffic, and are normally used to connect switches to other switches or to routers. It is very often the case that small-business grade switches, such as the Cisco SG200, designate each port as a Trunk port by default.

    To keep our example simple, we’ll assume that the device(s) connected to the switch are not configured, or are unable to be configured, to tag Ethernet frames with a VLAN ID. Consequently, we’ll configure ports 1 and 2 as Access ports, and assign each membership in one of the two newly created VLANs. Furthermore, we’ll also assume that port 25 is currently being used to connect the switch to the pfSense LAN interface, and configure it as a Trunk port, assigning it membership in both of the newly created VLANs.

    Navigate to VLAN Management->Interference Settings, select port 1 and then select “Edit”. Change the Interface VLAN Mode from Trunk to Access, then select “Apply” (See Figure 3). Now follow similar steps to configure port 2 as an Access port.

    Screenshot showing port 1 being configured as an Access port in the Cisco SG200-26 switch

    Figure 3

    Next, navigate to VLAN Management->Port VLAN Membership, select port 1 and then select “Join VLAN”. Since Access ports can be added as untagged to only a single VLAN, we’ll need to first remove the default VLAN the switch automatically assigns to each port (usually VLAN 1). Highlight VLAN 1 by left-clicking on it, then select the arrow icon to remove it from the interface. Now highlight VLAN 10 by left-clicking on it, then select the arrow icon to add it to the interface, ensuring that “Untagged” is selected from among the options under “Tagging”. Select “Apply” when completed (See Figure 4). Now follow similar steps to join port 2 to VLAN 20.

    Screenshot showing port 1 being joined to VLAN 10 in the Cisco SG200-26 switch

    Figure 4

    With switch ports 1 and 2 configured as Access ports and joined to VLANs 10 and 20 respectively, any Ethernet frames that enter those ports will be tagged with the appropriate VLAN ID. Now let’s configure the port 25, the port that is connected to the LAN NIC in pfSense. This port will be configured as a Trunk port and joined to both VLAN 10 and 20 so that, in addition to passing the Ethernet frames from from devices attached to the other ports on the switch to pfSense, it will also pass Ethernet frames tagged with VLAN IDs 10 and 20 (from ports 1 and 2).

    Ensure that port 25 is configure as a Trunk port, then navigate to VLAN Management->Port VLAN Membership, select port 25 and then select “Join VLAN”. Highlight VLAN 10 by left-clicking on it, then select the arrow icon to add it to the interface, ensuring that “Tagged” is selected from among the options under “Tagging”. Follow similar steps to join port 25 to VLAN 20, then select “Apply” when completed (See Figure 5).

    Screenshot showing port 25 being joined to VLAN 10 and VLAN 20 in the Cisco SG200-26 switch

    Figure 5

    That’s it for configuring the switch. If your switch supports both a running configuration and a startup configuration, make sure to save the changes you’ve made to the startup configuration so that they are not lost should the switch reboot for any reason.

    Configuring pfSense

    Now we need to create and configure VLANs 10 and 20 in pfSense. Navigate to Interfaces->assign and make note of the device driver name assigned to the LAN NIC. For our example we’ll assume the device name is “em2” (See Figure 6). The LAN interface will serve as the “parent interface” for the VLAN interfaces we will create in the next step.

    Screenshot showing the device driver name assigned to the LAN NIC in pfSense

    Figure 6

    Next, navigate to Interfaces->assign->VLANs and select the “+” icon. In the subsequent screen, select “em2”, the LAN NIC interface, from among the options in the drop down list under “Parent interface”, and enter the value of 10 under “VLAN tag”. Add an optional description for this VLAN under “Description”, then select “Save” (See Figure 7). Follow similar steps to create the VLAN 20 interface.

    Screenshot showing the creation of a VLAN interface in pfSense

    Figure 7

    After creating the VLAN interfaces, return to Interfaces->assign and select the “+” icon to add an interface. Select “VLAN 10 on em2 (vlan10)” from among the options in the drop down list, then select “Save” (See Figure 8). Follow similar steps to add the VLAN 20 interface. At this point you’ll notice that under the “Interface” column pfSense has denoted VLAN 10 and VLAN 20 as “OPT1″ and OPT2” respectively. Don’t worry, we’ll address that next.

    Screenshot showing the creation of a VLAN interface in pfSense

    Figure 8

    Navigate to Interfaces->OPT1 and select “Enable Interface”. Under “Description” replace “OPT1” with “VLAN 10”, then select “Static” from among the options in the drop down list under “Type”. For our example, we’ll use network for VLAN 10 by assigning the static IP address on this interface, and selecting the network mask of “24” from among the options in the drop list under the “Static IP configuration” section. The other parameters can remain at their default values. Select “Save” and “Apply changes” when complete (See Figure 9). Follow similar steps to enable the OPT2 interface, assigning it the name “VLAN 20” with a static IP address of and a network mask of 24. Now if you navigating back to Interfaces->assign you will see VLAN 10 and VLAN 20 listed and labeled with the description you added when enabling the interface in the previous steps.

    Screenshot showing the VLAN 10 interface being enabled and configured in pfSense

    Figure 9

    Next, we need to build a firewall rule for our two new VLANs so that traffic can pass to / from the WAN interface, and by extension, to the Internet. Navigate to Firewall->Rules and select the tab for VLAN 10. Select the “+” icon to create a new rule. For our example, we’ll build a simple outbound pass rule for any protocol in VLAN 10, similar to the way a typical LAN outbound pass rule would be configured. Select “any” from among the options in the drop down list Under “Protocol”, and under “Source” select “VLAN 10 subnet” from among the options in the drop list under the “Type” field. If desired, you may enter a description of this newly created rule for your reference under “Description”. The other parameters can remain at their default values. Select “Save” and “Apply changes” when complete (See Figure 10). Now select the tab for VLAN 20 and follow similar steps to create its firewall rule.

    Screenshot showing the creation of a firewall rule for VLAN 10 in pfSense

    Figure 10

    Unless you plan to assign static IP addresses to host devices, you’ll want to configure a DHCP server for each of the new VLANs. Navigate to Services->DHCP server and select the tab for VLAN10. Select “Enable DHCP server on VLAN10 interface”, then enter the range of IP addresses within the network you’d like the DHCP server to use under “Range”. Finally, enter an IP address for the network gateway under “Gateway”. Unless your requirements call for something different, you would typically use the IP address assigned to this interface as the gateway address. For our example this address will be The other parameters can remain at their default values. Select “Save” when complete (See Figure 11). Follow similar steps to configure the DHCP server for VLAN 20, this time entering a range of IP addresses within the network, and as the IP address for the network gateway.

    Screenshot showing the creation and configuration of a DHCP server for VLAN 10 in pfSense

    Figure 11

    Wrapping up

    At this point the LAN switch and pfSense should be configured to support VLAN 10 and VLAN 20. To test, connect a host device such as a desktop or laptop computer to port 1 on the switch. If you’ve configured everything as described, you should receive an IP address within the DHCP address range you’ve specified for VLAN 10 network The default gateway, DHCP server and DNS server addresses should be You should also have Internet connectivity. Connecting this same device to port 2 of the switch should yield the same status: you should receive an IP address within the DHCP address range you’ve specified for VLAN 20 network; the default gateway, DHCP server and DNS server addresses should all have address; and once again you should have Internet access.

    Be aware that as currently configured, each VLAN is routed to all other VLANs. If you would like to disallow some or all traffic to/from a particular VLAN you must create firewall rules explicitly stating what traffic should not be routed. Keep in mind that pfSense evaluates firewall rules on a first-match basis (i.e. the action of the first rule to match a packet will be executed). So, for example, if you wanted to block all VLAN 10 traffic from reaching VLAN 20 you might create a rule to that effect and move it before the one we created previously to route all VLAN 10 traffic to any destination (See Figure 12).

    Screenshot showing the placement of a firewall rule blocking all VLAN 10 to VLAN 20 traffic in pfSense

    Figure 12


    VLAN support in pfSense is not hard to configure nor complicated to manage, assuming your switch and NICs support this capability. To help explain the steps involved, we created two static VLANs on a commodity 24-port small-business switch and trunked those VLANs to the LAN interface on pfSense. We then created and added the VLAN interfaces, created the requisite firewall rules, and assigned each VLAN a unique /24 private IP subnet with host addressing handled using DHCP. Each VLAN is able to share the pfSense’s Internet connection and we are able further configure pfSense to prevent routing traffic between each VLAN, if desired.

      Question, what IP did you set the PFSense firewall to?

      I ask because I am trying to wrap my head around my configuration.

      My pfsense is
      My main lan is vlan5 or
      My subnet 10 or vlan 10 is
      My subnet 20 or vlan 20 is

      I set my trunk port to tag all vlans 1,5,10,20

      When I do set the uplink port to my pfsense to tag all these ports, I loose connectivity to the pfsense firewall.
      Any help is appreciated.

    3. iceflatline Says:

      Joe: In the example in the post, the LAN IP network was configured to and the PfSense machine’s address to

      Unfortunately, without knowing more about your configuration, it’s difficult to say where your problems may be occurring. However, you mention that you’re tagging VLAN 1 on the uplink port. Normally this is the administrative VLAN ID and you need not / should not assign it as usable VLAN ID. Are any of your access ports setup to tag incoming traffic with VLAN 1. If not, none of the incoming switch traffic on those non-VLAN 10 and 20 ports will be uplinked.

      I just (21.07.2014) did an office setup with 4x Cisco SG200-50p and 2x Netate (pfSense 2.1.4) C2758 and I have to say that indeed setting up VLANs with pfSense and the Cisco SG200 series is simple (as described in the above guide) and cost effective.

      Martin, pretty sweet setup. Thanks for sharing.

    10. ncurses Says:

      you said that there is already routing enabled for this VLAN, right? on my setup, if i don’t set the GW to another route(pointing to my other WAN connection) routing between VLAN works but if it set it to exit to another gateway routing between VLAN seems broken… hopefully this make sense… :)

      do you have this issue?

      i have vlan 1 as the default vlan in subnet and i have installed pfsense and now want to shift my network to vlan environment .. so i start creating vlan 10, 12, 13, and so on.. and still i have vlan 1 also .. i have main switch foundry bigiron 8000 which the facility of dual mode per port which help in traffic transfer of both tagged as well as untagged .. so my vlan work fine but the problem is traffic from untagged to tagged vlan can not be passed …. kindly help me to resolve this problem….
      i want traffic from vlan 1 to be passed to vlan 10 12 13 etc and vice verse …

    14. iceflatline Says:

      sraza, it’s going to be difficult to offer you much help here. I’m not familiar enough with your particular network setup or switch. As a general comment though, you’ll want to make sure that when LAN traffic comes into the ports you’ve selected for VLANs, those ports are tagging traffic with the correct VLAN ID. You’ll also want to ensure that traffic is exiting the port connected to the pfSense box tagged with those same VLAN IDs, including the default VLAN 1 ID. By default, pfSense will route traffic between the all VLANs. If you don’t want that to happen, you’ll need to create firewall rules explicitly stating what traffic should not be routed.

      I would further suggest doing a little ‘Googling’ to see if there are some unique setup concerns with your particular switch.

    19. Jason Says:

      Just so I have this right, this is what the LAN looks like:

      em2 Physical NIC – – DHCP disabled?
      VLAN10 on em2 – – DHCP enabled
      VLAN20 on em2 – – DHCP enabled

      Do you have to give the physical NIC an IP, or can you just give IPs to the VLANs? If not, is there a benefit to giving the em2 NIC an IP? Is there a way to have pfSense tag untagged packets to default to VLAN10 or 20? I have little experience with setting up VLANs. I’ve done little work with them on Cisco UC devices using CCA, so I’m just trying to wrap my head around this concept.

      This is a great article, and I thank you for posting it. It has helped me a lot.

      Best regards!

    20. iceflatline Says:

      Jason, the configuration you’ve provided looks correct to me. As to whether or not you can just provide IPs to VLANs, I don’t know for sure. Usually the LAN NIC is already assigned an IP (usually the first host address in that subnet). You’ll have to experiment. With respect to tagging, pfSense will automatically tag packets appropriately.

    21. Jason Says:

      Sound good to me. Thanks for the quick response! Like you say, I’ll have to check it out when I get a chance.

    24. Tony Says:

      I followed your instructions to the letter. I am still having problems. I am using a Netgear WNDAP330 as a wireless access point. There is a private SSID which is on our 10.10.x.x corporate subnet and I’m trying to get another SSID for guest WIFI. The SSID is called GuestAccess and is configured on VLAN ID 5 with a network subnet of DHCP is enabled on the WNDAP330. The switch port (GE18) on Cisco managed switch is a member of VLAN 5, tagged. The port the pfsense box is on is also a tagged member of VLAN 5.
      The interface is not seeing any traffic. Not sure if DNS is working. Wireless clients connect, but can’t get to the internet. Can you help? Ask any questions you need to get the information you need to help.

    25. iceflatline Says:

      Tony, I have a similar setup. I have a wi-fi access point on a separate VLAN for guest use. However, instead of the allowing the AP to provide DHCP support or act as the default gateway, I have it configured to simply act as bridge. As such, the pfSense box is the default gateway for all clients connecting to the AP, and the IP addresses are provided by the DHCP server configured on pfSense for that VLAN. The problem you may be having is that your AP may still acting as a default gateway, and so may not be properly configured to route traffic upstream to pfSense. To start troubleshooting you may want to remove the AP and connect a PC or laptop directly to that switch port and see if you can connect.

      Hi… Your post is very great… I need to make vlan on my pfsense but to do balancing in my pfsense. So.. I have 9 DSL. One Pfsense Server with an additional NIC 10/100/1000mbps Tplink. I havent prove this configuration to do that i want. Will it work great with this configuration but connecting in wan port instead of lan port? I wanna create 9 Vlan to plug 9 DSL to do balancing in pfsense. Will work your steps? Thanks…

    27. iceflatline Says:

      Enyerberth, I do not know. I suspect you could set it up that way but I’m not sure how well pfSense will load balance across that many WAN interfaces. Why do you need so many?

      currently i have 2 loadbalancer Tplink 470+ with 4DSL Each LB. Each DSL has 10MB but the LB doesnt get it. They dont work well. Just get 4MB and their balancing is not stable, because of it i wanna balance directly by pfsense but my server just has 3 additional NICs and i need 8 and because of that i wanna set my cisco switch up as VLAN for my 8 DSL .

      em0 Physical NIC – – DHCP enabled
      VLAN10 on em0 – – DHCP enabled

      One laptop connected to one access confirgured port of my SF300 cisco. I get the first IP delivered by the DHCP Vlan10. Port 24 of the Cisco switch as a trunck port (1U,10T) and rules configured I cannot reach Internet.

      Any help will be appreciated. Thanks in advance.

    32. iceflatline Says:

      enzo, thanks for your comment. Without access to the equipment it’s difficult to say. If you’re getting an IP address from the VLAN’s DHCP server, it sounds like you may not have the firewall rules setup properly, or perhaps something else, in order to pass VLAN traffic to the Internet.

      If your laptop NIC supports VLANs you might try adding it to VLAN 10 and connect it directly to pfSense em0. This way you could at least eliminate the switch as the source of the problem.

    33. enzo Says:

      Hello iceflatline, thanks so much for your response. I found the origin of my problem. In fact,Vlan10 traffic pass to Internet if I only disabled the portal captive Lan I have configured. This PF autentification functionnality, thrue Radius server, works fine and at the moment only with my Lan em0 trafic. I’ve tried to fix that problem with one more captive portal enabled for Vlan10 but unsuccessfull. Maybe some ports rules adjustments are needed . I’m triying to fix that problem. Any idea will be most and in advance welcomed. Regards

    34. iceflatline Says:

      enzo, I suggest posting your questions at the pfSense forums or in their IRC channel.

    35. enzo Says:

      I guess my problem comes from this rule : “PFsense captive portal can only run on one interface at a time.” In that case, what would be the solution for getting Vlan10 clients authenticated ? Thanks.

    38. Rayback Says:

      As far as I know,

      when using vlan with pf (manage the vlan subnets), you cannot use the vlan physical host interface as LAN (physical interface). there is a great troubles up to failure if you try to config vlans with a single host interface (LAN interface).

      In summary : let’s say you have,

      em0 = external interface (WAN)

      em1 = internal interface (LAN)

      If you must need to configure vlans, see to it never use the physical LAN, use the vlan em1_VLAN10 as your LAN, em0_OPT = WIFI and so on.

      so it is why from pf devs, they recommend use another extra interface to handle the vlans and leave the LAN interface alone for pf management, or for another separate use. You may feel the need of immediate access to PF’s gui that interface is a big and great escape from disaster you must face with vlans.

    43. Dylan Says:

      Very helpful article for setting things up. I do have one dilemma that perhaps someone here can help me with. My configuration is as follows:

      em0 – WAN
      em1 – LAN (labeled VLAN1 (default), untagged or access, connects to switches)
      opt1 – VLAN 2 on em1 (used for server data, tagged or trunk)
      opt2 – VLAN 3 on em1 (used for general network data, tagged or trunk)

      Here is my issue. Currently, both VLAN 2 and 3 are able to communicate with eachother and able to access the internet. However, they cannot access the switches which in theory should be connected directly to the LAN port and use an untagged or access connection. I would like to be able to access the switches via telnet from my computer(s) or server(s) which are connected to switch ports assigned to their respective VLANs. My question: How can I get VLAN 2 and 3 to be able to communicate with devices on the LAN interface? I would imagine it is just a firewall rule I have to add, but I have tried and tried and can’t figure it out.

      Any help is appreciated. Thank you in advance!

      Thanks for the great article! Maybe you can have a network diagram?

      Fuzz, good catch! Thanks very much for letting me know. It has been fixed. Adding a network diagram is a good idea. I’ll see what I can come up with.

    49. EricT Says:

      This almost worked but I couldn’t get the outbound traffic to reach the internet. It seems the problem was that a NAT rule is need in addition to the firewall rule described here. I assume that rule is created automatically when your mode is set to automatic, but I had mine set to AON on the Firewall NAT page. Once I created that rule, routing the VLAN network to the WAN address, everything worked fine.

      EricT, thanks for the comment. I have no such outbound rule in my configuration (pfSense version 2.3.1) and it seems to work fine. I now wonder if mine works only because it was upgraded from earlier versions, whereas a new install may indeed require an outband NAT setting. I’ll see if I can setup a test system and experiment.

      Thank you,

      my scenario is as follows.

      From the router,we have one Internet source. So I use Pfsense as the router, its basically a desktop computer running pfsense inside.It has two NIC Cards, (for the WAN and the other one for the LAN) that goes to the switches.

      In total we have 5 dlink switches, interlinked to one another.

      From the Dlink switches, 4 access points connects to them.This access points are the WAP200 type and they have support for multiple SSID.

      So what I intend to achieve is, create 2 VLANS, one for the staff i,e those who print, work here etc and the other VLAN for those guest who visit us occasionally.

      Guest who visit basically need internet only via WiFi.

      As such in the WAP 200, I have created 2 SSID’s, the guest wifi ought to be in a different network from the corporate one,(existing one)

      I thought i have to configure VLAN’s from the router, and the respectively to the switches, right?

      so that traffice tagged for VLAN 20 in the router goes to VLAN 20 in the switches, right?

      the other issue was for the access points, considering the access points has multiple ssid, how do i ensure SSID 1 gets traffic from VLAN 10 and SSID2 gets internet/traffic from VLAN 20

      thank you and kind regards

      Kefa, Thanks for your comment. Creating two VLANs – one for guest WiFi – is a good way to configure your network. I have a similar configuration. In my case, however, I use one access point for normal LAN access via WiFi using a single SSID, and another access point for guest WiFi access, with a separate SSID, over VLAN 20. If your access points – supporting two SSIDs – can tag traffic from each SSID using separate VLAN IDs then it should not be a problem setting this up as you’ve described. In this case you’ll want to configure the switch port they are connected to as Trunk ports supporting the two VLAN IDs you’ve configured at the access points. However, if the access points do not support VLAN tagging, then you’ll likely have to dedicate a single access point to each SSID then tag incoming traffic coming from them at the switch port as described in the post.

      Dear ,
      please find my scenario is as follows.

      i have 2 nos of ISP internet links . 2 nos pf core switches & 4 nos of distribution switches .All trafics are routed to core1 then firewall for internet . near about 3000 users inside my network . there are 30 nos of vlans are created in my distributions . is it possible that we can use pfsense for internet users inculding wifi users . i have extra Dhcp server & proxy server also.

      please suggest me or email-me.

    54. iceflatline Says:

      Laxmi, yes it should be possible. You may even wish to add a second pfSense machine for redundancy. However, I would also suggest you discuss your configuration with the pfSense community to determine whether there are additional configuration options you should consider – 3000 users is a lot of users. The pfSense forums and IRC channel is a good place to start.

      Thanks a lot!
      Learned how to set up vlans today based on this post! Fantastic guide! ;-)
      Keep it up!

      Regarding conversation with EricT (2016 Jul 31) about outbound rules on VLAN. I’ve just finished a lab setup which required changing from two LAN connections to the switch, to one 802.1Q trunk connection. I did have to install outbound rules for each VLAN to even connect to the switch.

      It was a great tutorial! THANK YOU!!

    57. Thankyou Verymuch Says:

      Used this guide to help me get my 3COM switch ==> Single Modem ==>virtual pFsense.
      All with a distributed vSwitch. Now I can vMotion pFsense without dropping a packet.

    58. iceflatline Says:

      telserv_ca, okay thanks for that information. As I replied to EricT I currently have no such rules but that was on an earlier version of pfSense that has since been upgraded. I still hope to duplicate the setup on a fresh install. Sounds like based on your experience that outbound rules will be required, in which case I will need to clarify in the post.
