I recently changed the green interface IP subnet. THere are many existing rules in DMZ pinhole settings that still refer to old subnet.
I was able to change the IP address via root access to the machine, and modify the port forwarding rules via the GUI. When I try to make changes to the DMZ pinhole settings, I click on the pencil, make my changes, click the update button then the screen just goes white and I can't do anything except go back. When I refresh my changes are not saved. How can I get around this?
