All connections into the hub should be straight through cables, including the
server. The only exception is that if you stack hubs, some of them won't have an
expansion port and you'll need a cross over cable. The cable connection from the
server to the inet would depend on how you're getting your inet feed. If it's
over a cable via a cable modem, some use a cross over cable, some use
straight... it depends on what your provider gave you. Your server has two
nic's, one for internet connection, the other feeding into a hub/switch box,
then you should run a firewall script the enables masquerading. That locking up
you mentioned, Did you modify a firewall script for your setup? It could be you
entered a host name incorrectly and iptables/ipchains is waiting to timeout
before it moves on to the next line in your firewall script.

For instance, if I re-run my firewall script when my ISP's smtp server is
off-line, the script will hang there until it times out and then continues on as
normal.
