hi dennis,
your description doesn't match your diagram, your diagram has the cable modem 
attached to eth1 of your firewall and the switch to eth0 of your firewall, 
which is exactly what i have, plugging the cable modem straight into your 
switch won't work unless it's actually not a switch but a router that can 
take dhcp assignments, (i'm assumimg that you use dhcp, if you have a  static 
this still applies since whatever the cable modem plugs into must be set up 
correctly), all my cables into my switch are patch cables and not crossover, 
i have to admit that i've never looked at the cable that came with the modem 
so whether that's crossover or not i don't know but using the one that came 
with the modem means it doesn't matter! - though if someone could enlighten 
me without my having to take the network down (and get down on hands and 
knees behind my desk!)
so perhaps you could clarify your setup, also when you say that your computers 
work fine i assume you mean with each other but not with the internet? 
otherwise there's something i'm missing here!
