Connecting through a new network

[A_PLUS]

My parents recently installed a new wireless network at their house. Enabling printer sharing etc. Well, for some reason, I can not connect to any of my poker sites, excluding UB. I tried deletign and reinstalling party, but no luck. I imagine it has something to do with connection coming through the router, which may have a different IP address than what I am set up for with the sites, but I really dont know. Has anyone ever ecountered something like that?
