This is a cookbook recipe on how to set up and run IP aliasing on a Linux
box and how to set up the machine to receive e-mail
on the aliased IP addresses.
IP Alias is standard in kernels 2.0.x and 2.2.x, and available as a compile-time option in 2.4.x
(IP Alias has been deprecated in 2.4.x and replaced by a more powerful firewalling mechanism.)
IP Alias compiled as a loadable module. You would have indicated in
the "make config" command to make your kernel, that you want the IP
Masq to be compiled as a (M)odule. Check the Modules HOW-TO (if that
exists) or check the info in /usr/src/linux/Documentation/modules.txt.
I have to support 2 additional IPs over and above the IP already
allocated to me.
A D-Link DE620 pocket adapter (not important, works with any Linux
supported network adapter).
