VPN Router configuration using RADIUS authentication problem
Dear Sir,



I have tried to configure Cisco VPN router to allow Windows client to use
PPTP to access to the VPN router. The authentication is using RADIUS.
However, I have problem to get the VPN router to authenticate user on RADIUS
database. The following is RADIUS debug:

Take a closer look at the RADIUS server's log files because the server is
rejectig the request - not the router (seems to be a mismatch between what
the router sends and what the RADIUS is configured for).
