Vonage and Wireless Router Setup

Tonight, I just setup Vonage on my home broadband connection. Vonage sent a RT31P2 broadband router with two phone ports. I already had an existing Linksys Wireless BEFW11S4 router. Here’s how I set it up:

Existing Router:

New Router:

IP Space:

DHCP Scope:

0. Plug in the cable from the cable modem into the Internet port of the RT31P2. Power cycle cable modem.

1. Plug in a PC into Linksys RT31P2 broadband router. Set the IP of the PC to so you can get to the IP of the router which is Switch the IP of the PC back to when done.

2. Change IP of router from to

3. Take a “straight through” (not crossover) patch cable and plug it into the uplink port (port 4) on the BEFW11S4. Make sure nothing is plugged into port 3 of the BEFW11S4 because the uplink port is shutdown when port 3 is in use. Connect the cable to any of the 3 LAN ports (not the Internet port!) This will create a “bridge” between the two routers. Also, make sure the routers are on the same subnets (both are sitting on 192.168.1.x, 192.168.2.x, etc).

4. Switch the BEFW11S4 from Gateway to Router model under the “Dymanic Routing” section so the BEFW11S4 acts like a switch. Disable DHCP on the BEFW11S4 if you have it enabled.

5. On the BEFW11S4, set the WAN connection to and set gateway and DNS to On the RT31P2, set it to “Obtain an IP address automatically”.

If you did everything correctly, you should see your Vonage phone number under “Line1 Status” under the Status page on the RT31P2.
