I would like to exclude the remote management port from the DMZ. I typically set custom port 4090 for remote administration of the router. If I enable DMZ then 4090 is directed to the DMZ'd device and I no longer have access to the router. I would like to enable / disable DMZ mode by remote access. Seems like there could be something I could paste into the firewall rules to always direct my custom port to the router so as to maintain control.
Edit - This is on Shibby 15 and an Asus RT-N12, but I think it is a common worm living in all types of tomatoes.
