Demand Dial ISDN and PPTP

[tracyr]

Customer has a Cisco 804 with ISDN. ISDN dials ISP and obtains a DHCP assigned address. I need the ability to connect to the 804 over the Internet using PPTP. Private addressing is used internally.

I have a script that pages me with the dynamic IP address of the ISDN dialer interface, so that's not an issue.

Can this be accomplished, and if so, what additional config statements would I need.

Thanks, Tracy Ryan

Of course it can be done. You can use dinamic crypto maps. This way you dont even have to know the address of the client trying to initiate the VPN (pptp) as long as the clinet know the key. Hope this helps. Another thing that you can do is define a loopback interface on the router and define the address as peer address in the crypto map.
