Multpile PPTP Session Through NAT for SAME VPN Concentrator

[mnlatif]

Hi,

I have a Cisco 1721 Router doing NAT Overload (with e0 address) for different client PCs. These clients also need to establish individual PPTP sessions with the SAME outside VPN 3000.

However the router would only let one client establish the PPTP connection and then all others are rejected.

Is is because of the router's inability to handle Mutiple GRE sessions to the same VPN Server for different clients ?

OR DO i need to configure some other parameters ?

To the best of my knowledge, you cannot do pptp using nat overload on a router using older IOS versions. However it seems that version 12.1.2T onwards, you can establish a PPTP tunnel while using NAT Overload. Please see Bug CSCdk60714.
