I'm no expert in the field here, but what he is telling you is that
they dont know
anything about your particular setup, and therefor cant help you. They
also dont
support home networks .

hmm, Ive been running 3.x and 4.x firewalls, and right now a 5.0-current
firewall, using
ipfw & natd, for more than a year on @home. Ive never had this problem.
One thing
I do see is dhclient. Were you assigned a static IP when you signed up?
In my case I was given a static IP address. In my logs I see
requests to udp dhcl
but those are all dropped by the firewall, and as to date I havent
run into a problem
like yours.

fyi I use a LinkSys and a Netgear pci for the firewall machine.
and old LattisNet 24 port 10base-T for a hub, and 5 machines (1 duel
boot)
on the inside network.

Id like to help more, but dont have any suggestions at this time. Im
presuming
you've done traceroutes and pings to your gateway and nameservers when
these
connectivity problems occurred?
