I want to set-up a VPN for the company I work for. Our developers should be able to access our office LAN from home via VPN with their Windows PCs. The office is secured by a Cisco PIX Firewall 6.2(2) which I configured to accept PPTP connections. (I have no activation key for the firewall for 3DES, so I cannot use the Cisco VPN Client.)
In my Windows I made a new dial-up connection to our firewall. When connecting the following happens (Ethereal trace):
1. Windows tries to open a PPTP connection to the PIX firewall.
2. The firewall accepts the connection.
3. A "Start-Control-Connection-Request"/"Outgoing-Call-Request" is answered by the PIX.
4. Windows sends a "Configuration-Request" which isn't answered by the firewall.
Windows keeps sending the configuration requests but the PIX (which receives the packets) wouldn't respond.
Here is a link to some configuration examples so you can check your configuration.
