I have a VPN between a 877 and a PIX 501. The 877 has a dymanic public IP address and the PIX is static, everything is OK untill the 877 is restarted (user unplugs the wrong plug) at which point I need to get the new public IP and reconfigure the peer on the PIX.

Does anyone know of a way round this so I dont have to reconfigure the VPN each time the router gets rebooted.

Yes I have tried the big sticker on the plug but that gets ignored.

Here's a configuration guide. Do note that the 877 will have to initiate the tunnel each time the IP changes.


I believe the command you need to adjust is removing the specific IP of the peer and allowing all IP's.

isakmp key cisco123 address netmask

Hope that helps
