Radius, Cisco 1600 and Windows Clients

[Agustín Ciciliani <agustin@maderonet.net.ar>]

Dear List,

I apologize if this issue has been discussed, but I couldn't find any docs that help me
out.

I have a network with a cisco 1601R connected to Internet and a radius server (simply an
ethernet switch with windows workstations, the router and the server running freeradius).

I'm trying to configure the cisco so clients dial to it, the cisco validate the user and
password with the radius, and if everything is ok, it opens the door to that client for
accessing Internet.

I've based my freeradius installation reading http://www.frontios.com/freeradius.html so
the server is running ok and the tests show me that it's validating as I need. The
communication between the router and the server is also ok.

The big problem is between the NAS and the clients. I read almost everything I've found in
cisco about VTI, VPDN, PPP, AAA and RADIUS, but I cannot make it work...

Besides I'm no sure about what kind of windows client I should use (pppoe as an ADSL
connection or VPN with the ip of the router to dial-in).

I'll appreciatte any comment, or perhaps you know a good howto or something that I could
read.

THANKS IN ADVANCE!!!

Sincerely,

Agustín
