Cisco 1921 Router with Verizon Bridged ADSL Westell Modem

Hi All!

   So.. I'm stumped. We got a 1921 router that works fine. We ordered Verizon Businss One Static IP ADSL. It came with a Westell Modem that we configured in bridge mode. When we do a test by assigning a static IP to our laptop then hook it up to the Westell it works fine. We can browse the web. Then when we assign a static IP to the Ethernet on our 1921 then connect it to the Westell it doesn't work. We can't ping out from the router to for example 4.2.2.2. From the router we can't even ping the default gateway (on Verizon's side).

   I'm thinking there's something very simple we're missing. We're really frustrated and would appreciate any input.

Thanks all!

-Tom

Hi Tom,

What is the purpose of putting the 2921 behind the Verizon Westell?  If you have users that need to access the Internet, you can connect a switch to Verizon router and let DHCP serves IPs from the router.  Can you post the config from the 2921 router?

HTH

The reason we want to put the 1921 behind the Westell Verizon DSL modem and to have the modem in bridged mode is so that we can use the one static public IP Verizon assigned to us. We want to be able to configure a site to site VPN to HQ (HQ doesn't have a problem they have a T1).

Here's our running config:
