      Post a copy of the following:-

      1. An ipconfig /all when directly connected to LAN2

      2. An arp -a when directly connected to LAN2

      3. Status-> Interfaces LAN & LAN2.

          Current status:

          1. I removed the "duplicate" static mappings so now LAN only has static IPs defined for the wired devices, and LAN2 only has static mappings for the WiFi devices.

          2. For my workstation, I removed all static mappings so it is just picku\ing up DHCP settings.

          3. LAN2 is defined as 192.168.2.0/25 - I only did this to force a change to be saved to see if it would solve the 255.0.0.0 issue

          4. I rebooted pfSense

          5. I double-checked the workstation is using DCHP - when the pfSense box / AP went wonky last night I had a fixed IP which may have caused the situation earlier today, not sure of anything anymore!

          Now, with workstation connected directly to LAN2, I am seeing an x.x.2.x DHCP assigned IP - as expected - but the subnet mask is STILL 255.0.0.0

          Attached items as requested:

          • ipconfig /all
          • arp -a
          • pfSense Status > Interfaces

          IpConfigAll.txt

          Arp-a.txt

            192.168.2.1 00-0d-b9-50-e9-82 dynamic

            hmmm your getting DHCP from the pfSense LAN2 interface, thats why I asked for the arp -a, to tie in the DHCP server IP and the MAC address.

            The subnet mask is now /25 rather than /24.

            Can you post a screenshot from the LAN2 config and the DHCP settings for LAN2.

                Remove DHCP option 1 and try again.

                No need to go anywhere near the options config for standard users.

                  You've got to be kidding! That just looked like a default panel with nothing saved - pfSense usually adds rows of saved items in a table underneath.

                  Anyway, I needed to add another row to get a delete option but when i did, the DHCP assigned mask is immediately the expected 255.255.255.0 and from my x.x.2.x workstation I can access the NAS webgui on x.x.1.x

                  So grateful - many, many thanks.

                      You should be getting a mask of 255.255.255.128 if you have a /25 mask set.

                        Yes, that's what I get with the /25 setting. Thanks again.
