Simply connect the Ethernet port of the modem to the Internet port of the router, and ensure that the router is configured to get its Internet IP address via DHCP.
Initially when you first connect the modem to the router, it will hand the router an IP address in the range 192.168.1.x. This means you need to ensure your router does not become confused by using the 192.168.1.x range for its LAN interface. If it does you should change the LAN IP range of the router for example to 192.168.0.x.
The actual configuration of the DSL-300T, can take place from a computer connected to the router, simply by opening the web page
http://192.168.1.1/ and setting the modem up as shown above. Then once the modem is configured and has authenticated with the ISP the Internet IP address on the router should become the one your ISP has assigned you. Some routers may need you to manually trigger the renewal of the IP address on the Internet interface, either via their web configuration or switching the unit off and on again.Simply connect the Ethernet port of the modem to the Internet port of the router, and ensure that the router is configured to get its Internet IP address via DHCP.
