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.
