      Is there a method I should use to swap two interfaces that are already in service?

      I tried just swapping them in the assignments page, save->apply, but could never reestablish WAN connectivity. I had to set them back to their original settings and reboot to get it to work.

      thanks

        That should work. Obviously you would also have to swap the cables to the NICs to use the new assignments.

          hmm, did swap the cables as well. I'll have to wait for later when everyone doesn't get mad at me and try again.

          thanks for your help

              Hmm, if I change my WAN to a different interface (re2->re1)it can no longer connect to the internet. As soon as I change it back, it connects just fine.

              Things I've done.

              1. verified with my ISP that there is no MAC address limitation
              2. tried changing via GUI
                3 tried changing via command prompt
              3. rebooting after every change both router and modem

              any other idea on why I can't change from re2 -> re1? I know that re1 works as I use it as my failover interface.

              thanks

                What kind of internet connection are you using and what modem?

                  That's one of the issue I experienced in the past when trying to use Realtek NICs in FreeBSD, a sudden increase in small packets crashed the interface. You can try to use the driver from Realtek instead of the FreeBSD included one, check the hardware forum for it. Best would be to use Intel or Broadcom based NICs.

                    It is a fixed wireless modem from Ubiquiti. I don't have the name of it, though I could ask if that helps.

                      I have a 4 port Intel card, just don't have a low-profile bracket for it. Ordered one so when it comes in I'll swap it over.

                      thanks for the suggestion.

                        You could try the alternative Realtek driver: https://forum.netgate.com/topic/135850/official-realtek-driver-binary-1-95-for-2-4-4-release/

                          how do I verify I have a Realtek chipset?

                          NM: google helped me:
                          pciconf -lv

                          reports all three are Realtek

                            Yes, the reX interface names confirm that.

                              Was just ruling out a Puma6 equipped modem issue.. UDP traffic on those can cause this.

                                It happened again.

                                I did verify that the new drivers are loaded

                                  Does this mean that it started to occur suddenly or from the first time you started using a VOIP service?

                                    Not really. It shows the link went down and then came back up after 3 seconds.

                                    I would still try to swap out re2 for a different NIC to verify the fault stays on the NIC.

                                    What is it actually connected to? Does that log anything?

                                    You might try adding a switch in between the WAN and whatever it's connected to. The link should never go down with that in place.

                                      I've had voip on this router over a year, it just started happening.

                                        Then ask your ISP if anything about your circuit has changed on their end. Just to cover your bases.

                                          I ordered a low profile bracket and when it comes I'll remove the 2 port realtek and replace with a 4 port Intel.

                                          I have tried swapping re1 for re2, but it never works. I tried it several times and for whatever reason re1 never works. I tired in the GUi and via command line. Now re1 works great through my failover WAN. I don't know why I can't reassign the interface. By that I mean get it to work. Pfsense says it is reassign, but it never assigns the static IP and doesn't work.

                                          The WAN is only connected to my modem/antenna. I run pingplotter and can see that the WAN drops as soon as I answer the phone call. Interestingly I've never had it drop if I let it ring more than once :)
