1.  How's connectivity?  Can you ping by IP address?
Try 66.94.234.13 or 216.109.112.135, for example.
What's the output of `netstat -rn` ?

2.  Are you running a firewall on your gateway that
is either a] not handling NAT properly, or b] blocking
DNS packets to your box at 192.168.0.3?

Just my 2 cents...HTH,

Kevin Kinsey
