Configuring the Switch Ports

This optional guide shows the steps required to configure the LAN and OPT ethernet ports to be on the same VLAN.


When connecting to the webConfigurator, be sure you are NOT connected to the port you are going to configure or you will lose connectivity during this procedure.

  1. Open the pfSense® Plus WebGUI and log in.

  2. From the menu, navigate to Interfaces > Switches.

  3. Go to the Ports sub-menu.

  4. Click on the Port VID for OPT. Change the default value from 4092 to 4091. In the lower right-hand corner click Save.


    At this point Interfaces > Switches > Ports should look like the following:

  5. Click on the VLANs tab.

  6. Click on the fa-pencil button for VLAN group 3.



    VLAN group 0 must remain in place and VLAN groups 1-3 must include 0t as a member, in order to function properly.

  7. Click Delete for Member 1, then click Save.

  8. Click on the fa-pencil button on VLAN group 2.

  9. Click on the Add member button. Enter Member 1, uncheck tagged and then click Save.

  10. Confirm the configuration matches the screenshots below:



Unlike software bridging, traffic between ports 1 and 2 will never leave the switch chip so it will perform at switching speed. You also cannot filter traffic between the two ports as pfSense® Plus will never see it, just like with any other (external) switch.
