Late last year I had a similar problem and found an answer in the
archives suggesting checking the firewall settings.  Here's and excerpt:

"I found while looking at the Linux Firewall module in Webmin that only
lo was set to accept any traffic but that eth0 was not. I added a rule
to accept any traffic on eth0 and now my internal workstations get
through the firewall just fine."

It worked for me, YMMV.
