      previous VM

      Is pfsense running bare metal now or still a VM?

          Are you using fiber ?

          I in "old days" Fiber SFP's were "locked" to the bitrate they (optics) were "Born with"
          Copper could to speed switching.

            Yes it's fiber. Does this make it impossible?

              If you are using a multispeed transceiver, then 1 or 10 gbps is possible. There are 1 gbps SFP transceivers (SFP + is backward compatible), there are 10 gbps SFP + transceivers and 1 or 10 gbps multispeed SFP + transceivers. It depends on what you use.

                The available link speeds depends on the SFP(+) module you're using.

                For example DAC cables usually don't allow setting a link speed at all.

                Using a 1G module is probably the best way to ensure it.

                  I thought so as well, so I tried with a unifi transceiver that I use in a switch set to 1gbps. But there were still not any option to choose a different link speed in pfsense. I even rebooted the router with the new transceiver installed, and there is no option to change anything.

                    Okey, I will try that. Thanks

                      Alright. I swapped around some transceivers temporary in my switches to try it out. I can not test it fully, due to my layout with switches in different rooms. But it seemed like it connected to the switch with a 1G transceiver on auto negotiation. I have ordered more transceivers now. Thanks a lot.

                        Just to confirm, if anyone else reads this thread and have the same problem.

                        Installing a 1G transceiver in the SFP+ port on auto negotiation, did solve my problem, and I'm using it as a WAN interface now on 1G speed.
