    Hi

    I have a quad intel network card installed and my LAN is currently in port igb0, I want to move this to igb1 so i can put my PPPoE modem in the first port instead of using my onboard network card made by RealTek.

    So I

    • goto Interfaces --> Assignments
    • Change the Network port of the LAN interface from igb0 to igb1
    • click save.
    • The page reloads but the LAN is still on igb0
    • pfsense can no longer be pinged and shortly afterwards is unreachable.
    • I then physically go to the pfSense box and restart it and it goes back to normal with the LAN still on igb0

    How Do I fix this?

    I am running:

    • pfSense v2.6.0
    • pfBlockerNG v3.1.0_9
    • Snort v4.1.6
    • some other minor packages

    Any help would be appreciated

      You can't change an interface that's in use from there.
      Open the console, do number "1. Assign Interfaces".
      Make a note of all the interfaces and assignments it lists then change as you want but make sure you assign all that were already assigned. It will remove them if not.

        Just a couple of followups

        • when you say in use, do you mean that there is a cable physically plugged into the ethernet port or that LAN is used in rules or things in the pfsensebox
        • if i use the console, will it wipe all of my gateway and interfaces out?

          1. Not sure to be honest. I just know I tried too many times and it would never work.

          2. Won't hurt anything. At least it never did for me.

            I will give it a go and post here. i will also raise an feature request to put a warning up when trying to change a network port on an active interface.

            also i might do a feature request to change a live connection but would require restart option

              The info helped, try this.

              • Login to the pfSense GUI via any other route that the LAN interface. If you do not have another method, set one up (OpenVPN, LAN2)
              • Unplug the LAN ethernet (might not be needed but you need to do it any way)
              • Interfaces --> LAN --> Edit --> Disable
              • Save and apply changes
              • Interfaces --> Assignments --> LAN --> Change the Network port
              • Save changes
              • Interfaces --> LAN --> Edit --> Enable
              • Save and apply changes
              • Plug the ethernet cable into the new socket
              • should be working now, but a reboot for me did not harm

              And obviously reconnect via the LAN to test
