I am successfully running some machines on real IP addresses 203.46.4.xxx
and some on private addresses 192.168.0.xxx all on the same physical
network.
I didn't do any aliasing of the NICs at all. All machines use the firewall
on 192.168.0.1 as their default gateway. What I did do was to add a command
on the end of the /etc/rc.d/rc.local files to add a route to 192.168.0.xxx
like this:
route add -net 192.168.0.0 netmask 255.255.255.0 dev eth0
route add default gw 192.168.0.1
The firewall machine has IPChains set up to disallow any private IP
addresses that come from the outside and allows forwarding of traffic
between the 2 subnets internally.
Technically it *is* better to have the Internet servers in a DMZ but I did
it this way for convenience and IMHO it is still secure enough.
