I am hoping someone can provide suggestions. I am trying to reassign existing interfaces (LAN and several of my OPT interfaces) to different physical ports so I can take advantage of the 2.5 GB ports. When I select the drop-down box next to any of the existing interfaces and try to assign it to an unused interface, I see the new interface in the box. But when I click “Save” and expect the screen to refresh with the new interface, everything re-displays as if I did not make any changes. I am logged into the UI through a switch interface, not directly into the existing LAN port.
Do I first need to unplug the Ethernet cable to kill all current states? Do I need to plug a PC directly into the LAN port (but that is one of the interfaces I wish to change)? Do I need to do all such changes through the Console port or via SSH? I have not been able to find any pfSense documentation addressing this problem Everything i read seems to indicate that the drop-down and Save steps in the GUI should work.
Thanks for your quick response/help. Tom. I was not trying to reassign to an existing interface. But your suggestion to first disable the interface did the trick. In case this helps anyone else, I had to first disable the existing interface and Save the change. Then I could successfully select the new assignment (an open port) and save that. Then I had to go back to the interface and re-enable it. It took those 3 steps, but the GUI worked fine.
