I have been running the 088 AIO firmware on my Asus RT-N66U router for several months without incident. I have UPnP enabled and no manual port forwarding rules established. My Xbox 360 works fine as does the Wii and until tonight my WHS remote access worked fine. I would get periodic notifications that my WHS port forwarding check had failed but the notification would be cleared within a few minutes and then remote access would work fine as always.
Now I cannot access my server remotely and when I check the UPnP section of the Port Forwarding tab in the Tomato GUI I don't see any forwarding rules except TCP port 4125 for WHS_4125. The port 80, 443 etc. are not shown.
Any ideas what the problem is?
