woohoo! thank God someone else is having problems... I've been struggling with this for a while now, and only recently discovered that using port forwarding with "virtual server" is a workaround.
I'm having the problem with a different app, however. The Ventrilo server software (www.ventrilo.com).
If I forward ports 3784(TCP/UDP) and 6100 UDP, and reboot the router, and then start the server it will work... until I close the server. When I restart the server no one can connect to it, not even locally (even tho it is correctly binding to the ports).
If I use virtual server instead of port forwarding, it works as intended.
UPnP is disabled. fw1.21(1.20 was the same). I also tried getting this to work on a fresh install of vista x64
I have not done a hard reset of the router. (does hard reset also mean I have to manually reenter all my setup stuff again? or is the settings import safe?)
