[expert] 2 IP address - 1 nic

[S. Newhouse]

Don't know how you could do it? 

What do you need it for?  

If you want your private network to access the internet through the
public one, you should route from your internal addresses to the public one.  

E.g. if host1 is 203.53.100.1 and host2 is 192.168.2.1, both having
eth0 as their ethernet devices, do the following. 

  go into host1 and type 
  route add -host 192.168.2.1 dev eth0

  go into host2 and type
  route add -host 203.53.100.1 dev eth0

then you can do ping, telnet, ftp,  whatever you want, etc, 


I'm sure there are other ways to do it, but this works and is easy for 
small networks.  For large networks, check into routing and ipchains.
