R2R VPN Connection with unknown peer

[bkother]

Hi there!

We are trying to set up a VPN-Connection using the Internet.

One Router (3620) has a public IP Address, the other (1750) will dial up an ISP obtaining an unknown public IP address.

Got someone have a hint for the configuration ?

Thanks in advance!

You'll need to setup the 3620 with a dynamic crypto map to allow from any IP address (unless you can get your ISP to fix the address every time), you can use a wildcard in the crypto peer entry. Although this seems less secure, you can still apply lists to what data goes from LAN to LAN with your crypto ACL's.

Thanks for your replay! I foung a configuration that is working well. The tunnel is beeing set up an I can ping Privat-to-Privat Network-Clients.

I set up route-map on both Sides to disable NAT for the privat-networks. When I try to telnet a device on the other network, the C3620 causes a Software-forced crash ??!!? and reboots. (Version 12.1.6)

Any clue?

Thanks Mike
