Without any information on what the purpose of such a setup would be,
it's close to impossible to give you any recommendations. Is it
because you want to use your CentOS system as a firewall? a router? a
HTTP proxy? a network sniffer?

Or is it because you only have one external ethernet outlet and you
want to access the internet on your other systems, while the services
on your server still can be accessed from the outside? In the last
case, you would normally just put your server on the LAN and do
port-forwarding on your router. If it's because you want your server
to be "outside" of your LAN, a more correct approach would be to setup
a DMZ zone on your router, dedicate one of the LAN ports as DMZ port
and connect your server there.

> I wonder if anyone has set up a system like this?

Perhaps, perhaps not, depends on what the purpose of the system is.
