I have a Cisco 2500 series router. This may a VERY STUPID question,
but is it possible to set this up to act as my DSL router? I have a
Westell that came with the Bellsouth service. What I would like to do
is pretend this is a client, and we're using the 2500 series as the
only router.

It has two ethernet interfaces, by the way. I just don't know if on
the one interface if there's something special to configure because of
the DSL service.

Perhaps

Post the output of show version from the Cisco router

What is the model number of the Westell modem ?

If you connect a Windows PC to the Westell modem and configure the PC
for PPPOE, can you connect to the Internet ?

So, you must have a 2514. But anyway, you do realize the 25xx was designed
to basicly drive a T1 and a half or so? I don't know what speed DSL
you have, but it could very well slow your DSL down by having it in
there if you have more than T1 speeds.

It depends quite a bit on what your Westell device actually is. Are you
bridged? PPPoE? Routed? PPPoA?

I don't think you can get an image for the 2500 series that does PPoE. They
have been EoL (end-of-life) for at least 8 years.

It seems as if the Westell acts as a router and runs DHCP. When I go
to the connection configuration section I see the following:

VPI / VCI 8/35
Protocol PPPoE Bridge Ethernet

User ID: username@bellsouth.net
Password Provided by your ISP.
Confirm Password

Static IP Address Primary DNS Server
IP Gateway Secondary DNS Server

Connection Type: On Demand

The Cisco router is a 2514. Does this mean I can't use it?
