I need to be able to use a Cisco 877 ADSL router to form a VPN tunnel to another on the end of an ADSL connection where I can't get a fixed IP address.
That remote site is using the dynDNS service
While the IOS config will accept a hostname instead of an IP address when I view the config it show as an Ip address. Therefore I assume it does a one-time DNS lookup and stores the IP address in the config.
Is there a way to get a Cisco device to accept a dynDns type name as the tunnel endpoint?
