R2R VPN Connection with unknown peer

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!

Re: R2R VPN Connection with unknown peer

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.

Re: R2R VPN Connection with unknown peer

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
