well most importantly are you DMZ'ing your Dreamcast IP. That always ends up being the #1 problem lol.
ok, I did some reading up on the subject and tried to the stuff you posted here viewtopic.php?t=9627
so I put in Quake 3, saw what ip my dc is using & changed the DMZ of my router/cable modem (I only have the modem on the wall, there's nothing else between it, no router, no firewall, nothing...Quake 3 also works online btw, but still no PSO...it keeps saying to check if my provider settings are correct and it disconnects...
seems I'm in the same boat as the guy in that topic, the ip is 192.168.X.XXX and I can only change the last 3 digits
so I changed that to the ip quake gave me, opened a port in my router, but pso still says fuck you...which I find odd in itsself, coz I've always been able to play pso by simply plugging my bba directly into my modem...
