      Btw : Interesting issue : blaming the firewall when a "user" installed some random ware ...

      I know, that's why I am fighting against the local IT.
      Now I have access on a vm natted on the "new chinese firewall" and I can work also from Vsphere console, but I wouldn't like to start from scratch just only I need to change two IPs, it is very disappointing!

        I'm not clear if the WAN and LAN are in the same subnet now, and you're trying to fix that? Because you wouldn't ever change them to the same subnet. If you're trying to swap them, perhaps change one to some other made up subnet temporarily...

        WAN A
        LAN B

        WAN C
        LAN B

        WAN B
        LAN A

        When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

          et's take, for example
          LAN net is 192.168.6.0/24
          WAN net is 20.30.40.0/24 GW 20.30.40.254

          My old IPs are
          LAN 192.168.6.1
          WAN 20.30.40.1 GW 20.30.40.254

          I have changed first LAN address with
          192.168.6.10

          Then WAN address with
          20.30.40.10 GW 20.30.40.254

          The system is stuck. I can connect with a slow refresh to the interface but I cannot browse and/or update the system.

            OK so the two interfaces are not in the same subnet.

            I have no idea why you would have the trouble you describe, by making those changes. Are you sure neither of those IPs are already in use on other devices?

            Have you tried changing just the LAN IP, and restarting?

              The question is that the WAN IP is now used by another device, so I need to change it too

                Get actual console access (not SSH) and use option "2" to change the IPs and then reboot it for good measure.

                    I was just trying to find out at what step you lose access.
                    You should not be losing access.
                    If the current WAN IP is in use by another device I would expect both of those to have trouble and would be surprised if you could connect out from the pfSense to the Internet before changing WAN IPs.
                    I was trying to suggest the new WAN IP is also in use by another device. That would at least be consistent with your symptoms.

                      Please read from the top...

                      The local IT has disconnected pfsense nics from vsphere adn used its ips for the new device.
                      the new device is working without any problem, as pfsense before.
                      now I want to reconnect pfsense with UNUSED IPS (please, huh? I work in IT from 20 years)

                        OK but then the symptom of slow web GUI and inability to access updates is to be expected. The slow GUI happens because DNS isn't working and each try must time out on all DNS servers before the GUI moves on.

                        I was assuming the NICs were being reconnected after the IP change.

                        Not sure where to go from here. The only issue I've had with changing IPs is the rebinding check not allowing the new LAN IP but I think that bug was fixed a while ago.

                          Could there be anything in VMWare that is blocking the new IPs? I haven't used VMWare much, but vaguely recall some issues on our Virtuozzo cluster with ARP tables on the physical host.

                            pfsense can query the dns without any problem...
