OK so the Cisco has some NAT capabilities (10.0.0.x) and on top of that 
you're using a firewall that has extra NAT (192.168.x.x)?  This can be 
bad, it can cause major problems with some protocols (https, smtp).  I 
did this once...

I would first recommend seeing if you can get the cisco to not do NAT 
and allow your Linux box to do the authentication.

What does ifconfig -a tell you?

That and isn't Qwest going to be shoving MSN in your face soon?

Good luck,
