quick answer:  no.

long answer:  it has been discussed on this list previously that connection tracking DNS queries/responses on or for a busy DNS server (i think the number was ~ 200 queries/second) will slow the name resolution process down.  the reason being that the state creation adds noticeable, unnecessary latency, as most (all?) queries are one packet request--one packet response.

somehow i don't think this applies here.

oh--and i'll chime in with the obligatory:  don't run a DNS (or any other) server on your firewall.
