For an IPSEC application I require a router to ALWAYS query DNS to solve a host name. From what I've seen once it queries DNS, the router stores the response in memory and as long a you don't clear the host list (clear host *), it'll never ask DNS again.
That's exactly what I'm doing, BUT...the problem is that the initiating router caches the DNS resolution for the terminating router. If the IP on the terminating router changes (say a DSL connection), the initiating router still tries the previous IP address.
My configuration is exactly that. Tunnels work the first time around. The problem is that the IKE engine NEVER queries DNS again.
