only thing I could find online says that the ports are specific to each game. So I looked up socom2 for you and it says to open up ports 6000-6999 tcp and udp also make sure you have your ps2's ip address in the server ip address slot.(if it asks for one) but thats for to talk with the headset I also found the instruction book lol here's the link and read page 27 and 28 it tells you exactly what to do I bet you have to enter your dns ipaddy static ip of the ps2 and your routers netmask. so go to this link and look on page 27 and 28 if you need help finding your ipaddy and stuff go to start/run/cmd then type in "ipconfig"



sorry I can't be of much more help man heres that link
