It is extremely unwise to firewall using only one interface, for several 
reasons. I will admit that I do not fully understand all of them, but on 
the common sense level: if you want to protect your network from the BBI 
(Big Bad Internet [tm]), you certainly don't want "outside" and "inside" to 
be on the same wire. Just too high a probability of errors and an increased 
probability of snooping, sniffing, or other nasty behavior.

Cheers,
