I tried to connect to both your servers (naboo.swsim.com and
tatooine.swsim.com), trying both TCP and UDP, and they never connected,
although pings and traceroutes succeeded.  My guess is that there's some
packet filtering going on, blocking packets to TCP and UDP port 53 on your
LAN.

If you haven't installed a firewall, check with your ISP (GTE.net) to find
out if they're filtering.
