Some of us call this a "modem" connection. (bear with me, I just finished
beating the tar our of some files on Solaris, that are designed for GNU

The FIRST place to look is the ipmasq mini-howto (which isn't mini), on
http://ipmasq.cjb.net/ At the same time I would get a linux box, and
install the latest kernel, and latest ipchains, and possibly latest
ipmasqadm tools. Read the man pages, for some additional information not in
the howto. Then, if you're REALLY ambitions, head for the kernel source,
and read it to find exactly what it all does. :) None of these are
available in PDF that I know of, but many web pages have this info.

I suspect that this would take reading the kernel documentation, or the
sources. I don't think it's in the man pages.

The rules are waht you make them. Have fun, enjoy your reading.
