I would be very grateful if you could help me to solve this little problem:
I need to establish PPTP VPN to 877 modem/router from Internet.
The VPN client is a Windows XP standard VPN client.
I configured the router basing on the document:
"Configuring the Cisco Router and VPN Clients Using PPTP and MPPE"
And... It works quite nice BUT only when I use PAP protocol to authenticate the user.
When I try to use 'MS-CHAP' or 'MS-CHAP v2' I get error 691 on the client side
("Access was denied because the username an/or password was invalid on the doman.")
and on the router in the debuging log I can see the following:
105556: Oct 23 09:31:46.425 PCTime: ppp615 PPP: Phase is AUTHENTICATING, Unauthenticated User
105557: Oct 23 09:31:46.425 PCTime: AAA/AUTHEN/PPP (0000013F): Pick method list 'default'
105558: Oct 23 09:31:46.425 PCTime: ppp615 PPP: Sent MSCHAP_V2 LOGIN Request
105559: Oct 23 09:31:46.433 PCTime: ppp615 PPP: Received LOGIN Response FAIL
105560: Oct 23 09:31:46.433 PCTime: ppp615 MS-CHAP-V2: O FAILURE id 1 len 13 msg is "E=691 R=0"
105561: Oct 23 09:31:46.433 PCTime: ppp615 PPP: Sending Acct Event[Down] id[13F]
105562: Oct 23 09:31:46.437 PCTime: ppp615 PPP: Phase is TERMINATING
Could enyone help me find where I have made a mistake in the configuration?
The running config of the router is attached.
