I have setup a Cisco 877 as Easy VPN Server with Dynamic IP. The server works perfectly. Our ISP change the IP address every 24 hours which then update my hostname at DynamicDNS. My problem lies with the two Easy VPN Remotes which connect to the Easy VPN Server. They are also Cisco 877 routers. Everytime the Easy VPN Server's IP is changed the Easy VPN Remotes refuse to reconnect. The only way to re-connect is to go into the SDM, edit the VPN without changing anything. Come out and let the SDM run its commands. Even running the clear command from the command prompt doesn't have any effect except changing the Last Event to "connect". Any help will be appreciated.
You can specify up to ten servers by IP address or hostname as backup for the Easy VPN server, and order the list to control which servers the router will attempt to connect to first if the primary connection to the Easy VPN server fails.
Click to specify the name or the IP address of an Easy VPN server for the router to connect to when the primary connection fails, and then enter the address or hostname in the window displayed.
Click to delete a specified IP address or hostname
