I don't understand this part.  What is this router, exactly?

Do you have other computers on a local area network with which you would
like to use the Internet?  If so, you can have your Linux box work as
a router.

If you want multiple computers to share a single IP address then you need
to use IP masquerading (or just use a traditional proxy configuration).

Read the IP Masquerading mini-howto.

And be forewarned: you may not be able to get the slink ipmasq package
to work; I found it much better to configure IP masquerading by hand.
