warning, will robinson!  danger!  danger!

last time i checked, this pretty much assumes that you have a static ip
address assigned (particularly ipnat and in some cases, demand-dial ppp).
dynamic addresses are somewhat trickier, and you may need to do some
hoop-jumping to get ipnat configured for the proper address.

myself, i just punted on nat/ipmasq, since it's really only useful for a
limited set of things... i.e. not realaudio :-)
