Cisco 871 PPTP VPN Server Setup

Hello,

I am trying to configure a Cisco 871 to act as a PPTP VPN server on my home network. I have referenced Cisco's documentation regarding this which I will include below as well as a copy of my current running configuration and terminal monitor information from when I attempt to establish a connection. If there is any other information I can provide please let me know and I will do so in a timely manner. Thank you for your help.

When I attempt to connect from a Windows machine I receive the following error: 'Error 807: The network connection between your computer and the VPN server was interrupted.' 'The remote device won't accept the connection.'

When I attempt to connect VIA my mobile, I get 'The server has hung up'.

The 871 does detect the incoming connection which can be seen from the terminal monitor output: http://pastebin.com/weqCGweH

Current Configuration: http://pastebin.com/MaWrUZnv

Documentation:

Cisco 871 PPTP VPN Server Setup

I apologize I pasted information from two different 871 setups. I have one at my house and we also set one up in the engineering lab.

I have updated the running config and the terminal output from when the user connects. Thank you and sorry for the mis-information.


I just want to 'repost' the correct information below, this has updated terminal and configuration outputs.

Cisco 871 PPTP VPN Server Setup

Ok so I have made some progress. Some background.

====

Updated Config: http://pastebin.com/eZNYcxyu

====

I have 3 users setup:

- username Smokyo7 secret 5

- username David secret 5

- username test password 0

====

All users can connect with encryption turned off. Once encryption is enabled the interface goes down immediately after coming up. I will show this in a paste: http://pastebin.com/4VxXBuvq

====

As you can see the first connection is with encryption enabled and the second attempt is with encryption disabled. The only difference between the two that I can see is the following.

====

Mar 1 01:13:37.535: Vi3 PAP: O AUTH-ACK id 2 len 5

Mar 1 01:14:09.515: Vi4 PAP: O AUTH-ACK id 1 len 5

====

I am not sure if this is just the router saying 'ok id 2 drop or id 1 stay'.

Thank you.
