Dns Forwarders

All,
I have been trying to figure this out for the life of me but can not get it to work. I recently signed up for OpenDNS and can not get my UTM to change the DNS entries it uses from Comcast's. I have tried everything but nothing is working.

I have also tried using the DynDNS section and it never does anything but "DynDNS status is: An update attempt is in progress."

Can someone please walk me through how to get my DNS servers changed to use something other than my ISP's?

I believe that it is just showing you what the provider is assigning via DHCP. In my case, it shows my ISP DNS servers, but it is definitely not using them. Are you sure they are being used by the UTM? Run tcpdump on the external interface to see where they are going. I typically use something like tcpdump -nnvvXi eth2 'port 53' where eth2 would be your WAN interface, and you can leave off the X and the vv, I just use it for more detail since I am accustomed to using tcpdump in my dayjob. You are really interested in the destination addresses being used.
