whats going on?

i log in and try to reply to posts and if i take a long time typing i get a system bulletin saying im not logged when i try to post the reply. fortunately for you guys cuz i am long winded and probably too loquacious for my own good. but, is this because im behind a router with all my ports hidden and i lose my connection and your server cant re establish it. is there a port i can forward if this is the case?
thanx

Its just HTML. Port 80. If you get here you got it open. I'd say its your ISP.

of course, port 80, i knew that, dumb question. if my browser is open i requested the connection therefore my firewall lets it through. but some sights like msn gaming zone have many ports open(of course there are games running through them). im just way tired tonight. thanx. im still not sure what the problem is though. my isp is pretty good.
