If I understand correctly, you're using an 802.11g wireless router, judging from the "G" in the router model you said, but it's one of those routers that has a DSL modem built in. I'm assuming this because D-Link doesn't make a router called the "504G". Since there is no modem on the other side (the router is the modem) you can't try what we've been calling "connecting directly into the modem". What you'll need to do is go onto your computer and open internet explorer. Type in the URL 192.168.0.1, and if that is not found try 192.168.1.1. This will open up your router configuration utility. Here you need to open up whatever ports Sony told you to open and save the changes. After the router is flashed with the new settings, it should work just fine. If you can't figure out how to use the config, or if there is a default password on the router, check the router's manual.
