[expert] 2 IP address - 1 nic

[Timothy Litwiller]

how do I put two ip addresses to the same network card -

specifically I would like to use my public IP address 203.53.###.53 and
a private ip address 192.168.2.53 on the same card.

also if this works then what do I need to do to make samba function only
on the private ip#
