If anyone has read any of my previous posts, they'll know that I'm having PS2 problems.

I connect my PS2 via cat5e ethernet cable to a linksys WAG354G using a wired port.
I have created a DMZ in order to avoid any firewall issues.
I can connect the PS2 online to Star Wars Battlefront and it works fine.

When I try to connect to Everquest Online Adventures i get to the DNAS authentication screen, where it say connecting for ages and then I get a message saying you cannot be connected to the DNAS server, check your connections and try again.

When I try again, I get a DNAS -611 error.

I have a feeling that i need to forward some ports or something, but i'm a bit of a newbie to this networking and could really appreciate some help.

Many thanks
