How is this address 192.168.0.3 assigned?

The DSL modem provided by the phone company has only one output, which has forced me to use a router to connect my local network. I would like to use a more standard configuration for the modem and router, as it might make troubleshooting problems like this one with azureus easier. I assume this means having NAT running only on the router. The DSL modem has a static IP address assigned by my ISP. My boxes on the LAN also have static addresses. I've tried changing settings on the router and modem but then I can't reach the net from the LAN. Any suggestions as to how to proceed in making this configuration more standard (and transparent to this user) would be much appreciated. Jerry
