Suddenly lan traffic to dmz box is blocked by default deny / state violation ru

[rykr]

Pretty simple setup.  pi4 hanging off 3rd nic as dmz (no switch).  WAN rule port forwarding 80/443 to dmz box (192.168.2.10).  Accessing dmz box from inside my network worked perfectly when I set it up just a few weeks ago.  Now all I get is blocked by default deny / state violation.

Any idea what is up?

Just a followup -- apparently I have no problem accessing the dmz machine by direct ip address but cannot access it using the wan dns name with port forward.
