Several things come to mind.
I have no experience with that modem, but tell me about it when it is standalone with out the router.
Since it is ethernet, to set it up, do you surf into it and put your username and password in the modem? Or do you have to run a connection from a standalone machine?
I am going to go look that modem up, but if you surf into it, then it is also a router and you are connecting a router to router. If that is the case, need to work on the Nat routing in the modem or put the modem in bridge mode and let the router handle your DSL connection.
If you are with BS or Earthlink, if there is a way to bridge that modem, then connect it to your router, surf into the router and set it to connect via PPPoE with your correct user name and password.
To test, if you can bridge the modem, us the built in PPPoE client in win XP to connect. To do so follows.
Bridge the modem. connect ethernet direct to PC.
in win xp, goto start control panal, network connection and create new connection.
Tell it INTERNET, then MANUALY, then choose BROADBAND connection that uses user name and password, then continue though the wizard.
TEST your game.
I am going to try to find more info on your modem now.
