new firewall = internal DNS not working anymore

Hey everyone

I recently put a new firewall in place (a sonicwall tz215) and everything went pretty well--DHCP, internet, etc working, but one thing that went wrong was the DNS no longer worked. It looks like it's the internal DNS server, because when I ping internal servers from inside the network, I get weird external addresses (instead of 192.168.*.*, it's 8.8.something.something.

Anyone have any idea what might be going on here?

Thanks for the input!

Thanks for the assistance guys -- as it turns out the firewall was dropping packets from the DNS server because it considered it an IP spoof attempt b/c of a miswired switch. Ugh, what a pain.

Thanks!
