Socom 2 online

I have a Blitzz super g router and i'm trying to play socom 2 online with 2 playstations and i can only get 1 at a time to get online.I know you can have two playstations online at the same time.I can play socom and any other game at at the same time with no problem.Does anyone no if there is something i have to do to play socom 2 online with 2 playstation and 1 router at the same time?Any help would be appreciated.Thanks Badboy

me and my roomate play s2 all the time on a router. it was just plug and play for us.

Maybe you have open your router for direct NAT on some of the socom ports, hence all traffic on some ports will go to same ip?

u r using different DNAS accounts arent u ... ?
