i am attempting to connect a vpn tunnel between a WatchGuard Firewall and the Cisco WRV210. I am able to successfully connect the gateway and tunnel using static ip addresses, however, the Cisco IPSec VPN connection needs to be configured using DDNS as a means to get around the fact that the ip address is dynamic. Each time i enable the DDNS feature, the gateway and tunnel are lost and do not even attempt to connect any longer. This occurs regardless of if I configure the WatchGuard to use the DDNS entry or not. As soon as i enable DDNS, i lose the ability to connect the vpn gateway/tunnel regardless of the config on the other end. Any thoughts are appreciated.
