Since everyone likes to point their fingers toward security, I'll say
"nu-uh". If the other machines on the network don't have routable IP's,
then machines outside of his local network still can't get to the
machines inside his network, and the Linux box still gets to work as a
firewall. This could be done by configuring the NIC with a real IP, and
an IP alias that isn't routable. The only real down (that I can see) is
that all the network traffic is broadcast on the network twice, which
shouldn't be a problem if you're only using it for a cable modem.
Two nic's is an ideal setup, but one nic with an alias is the cheaper
version. Masquerading will work either way. Do whatever suits you.
