Two Network Devices, Same IP?

After doing some research, is the hypothetical scenario possible?


If I get a four block IP from my ISP (one is the broadcast, one is
network, two usable).

The ppp0 gets one, which would be static, and I'd know, so...

Could I set the eth0 on the linux gateway, the same as ppp0, and have
eth0 in the second linux box to be the fourth and final IP from my ISP,
and therefore have two public viewable servers?

I've read some conflicting reports as to whether this is possible.

Cheers

Use masquerading, or better, source NAT. With that, you only need 1 IP
for all PC's you have. Just redirect incoming packets to LAN using
destination port, for example.

What if I want to be a geek, and actually want two web servers? Or two
DNS servers, and host my own names? Or maybe get MSN File Transfer
working? Guess I can do that with port forwarding, but what if I want
two computers working, I can only port forward one port to one computer
at a time.
