Thanks for the reply pacov.
I double checked the Impulse Reactor and it was still 6100 - 6120, but I reset it to let it take its own settings. it chose ports 6112 - 6132. It's still within my 6100 - 6200 forwarded range, so it should be ok in theory.
Other settings are UPnP disabled and no DMZ. I'm hard - wired into the router to avoid any wireless issues. No proxy.
I haven't hosted a game for almost 2 weeks, but I'll give it a try when I get some more time. In the mean time, I'll also keep an eye out for a game that allows noobs. There aren't many that I'm qualified to join.
I'll open a ticket if nothing else works.
