Linksys behind Sonicwall prevents DNS resolution

Hi...I've got an interesting setup and an interesting problem.
I've setup a Sonicwal SOHO to VPN tunnel to our office HQ. Then I have
a Linksys WRT54GS taking the WAN in. I can access IP addresses at HQ,
but for some reason DNS is not resolving, I confirmed that NETBIOS is
working through nbtstat.

Also I tried accessing my home network from HQ and that doesn't seem to
work either.
Our HQ has a DHCP and DNS server, both not running on the Sonicwall at
that site...I'm curious if that could be the problem?

Anyways I would be grateful if anyone could provide some insight, and
please let me know what other information would be helpful to further
clarify the issue.

Thanks.
