Hey guys I wasn't sure where to put this topic but since I'm running a Windows OS I figured here is as good of a place as any. As of 2 days ago I had been able to get on PSN and play some online PC games that had to have ports such as 7500 UDP open to play. Now all of a sudden none, and I mean NONE of my ports are open. I've tried to access them using multiple programs and websites, and nothing is allowing access. I went back to factory defaults on my Linksys WRT54G router, re did all my port forwarding, and still nothing has worked. I hadn't messed around with anything and there's nobody in my household who would even know the first thing about port forwarding. I read up on some other websites via google and tried some of their methods but still no no avail. Can anybody suggest what the problem may be, and it's not the firewall/virus protection because as I had disabled both and the problem persists. The Linksys router is hooked up to a desktop PC in the other room, but I can access all settings from my laptop which I am typing this on. Thanks for the help!
You may want to put your PS3 in the DMZ of the router. This will allow any ports to hit the PS3. Also not sure if you heard or not but the PSN network is currently down. That may be the reason you can't log on to play.
ah yes I figured out that PSN was down earlier this morning. However that still doesn't fix the issue of none of my ports being open for PC games that I'm trying to play. Specifically I'm trying to get UDP port 7500 to open, although I can change that port to anything if need be. It's just frustrating because there seems to be no rhyme or reason as to why the ports suddenly are closed.
