VPN

We have 2 serves with windows 2003 servers/2 DSL’s.
We are running all the services in one server and enabled RAS. Pointing to one of DSL IP.
Everything is working fine.
Now my question is
Can i create another VPN on another server in the same network pointing another dsl rounter IP.
If so how to do that . I add the server role on the other server for RAS. But try to connet to the VPN, no sucess.
AM I missing any thing for this configuration?
Can we run two vpn sessions on both servers pointing to the different dsl?
Please help me out
