I'd like my router (2920) to use the opendns DNS servers rather than the ones that my ISPs give me.

I can do this on the lan setup screen. However, when I do this, they are given to all the DHCP clients too. I'd actually like the 2920 to give out its own address as the DNS server, and act as a caching proxy.

Is this possible?

Thanks!
