      The patch does not appear to work on 2.7.0.

        @ARAMP1 I just tested this on my 2.7 vm and seems to be working..

        So I created a static arp and it was there.

        I then rebooted and it was gone.

        I then applied the patch, and rebooted again and now its there.

          Must have been user error....I got it working. After a couple restarts and wondering what I did wrong, I reinstalled the patch and everything is working.

          Appreciate the help, gents.

            I’m seeing this behavior in 23.09. ARP table shows dynamic (expires in <time>) ARP entry instead of static (permanent).

            If I uncheck, “Create an ARP Table Static Entry for this MAC & IP Address pair” and then save.

            Then recheck “Create an ARP Table Static Entry for this MAC & IP Address pair” and then save.

            Then go back to ARP table, almost all the dynamic entries are flipped to static (permanent)

            Anyone else seeing this?

              @32G3LiQxu8 there seems to be an issue with when clients update their lease - there is this thread.

              https://forum.netgate.com/topic/184155/static-arp-in-dhcp-overwritten

              And this redmine

              https://redmine.pfsense.org/issues/14970

              So yeah if it has flipped to dynamic, a resave of the dhcp page where you set it as static will turn it back to perm, but it seems when client updates its lease again it will go back to dynamic.. See the thread linked to above, where you can duplicate it doing it by just having your client release and renew its lease.

              From the redmine it seems to be correct in the upcoming 24.03 and 2.8 CE releases

              "This is not reproducible on the latest builds of 2.8.0 and 24.03"
