Wow...I am not sure if I get your question right, but let me try to
understand.
You have a firewall, all machines go through, but that machine goes out to
the net through the same hub as all internal network traffic? That is
nuts. What that does it spam your packets upstream so anyone can sniff
them...exactly what you don't want.
The most common set up is:
---INTERNET---==Firewall(with eth1 and eth0)==---Internal Network
eth0 would only talk to the internet, and eth1 only the internal network.
