Short answer: I don't know :)

Longer answer: I seem to recall that you can use "slip" to connect boxes
with a serial cable ( I think it needs to be a crossover cable of some
sort ("null modem")  but I have never tried it)

There are two protocols, "slip" and "plip" - plip is for parallel port
connection.

I assume once you have a network connection to the gateway you can
configure NAT - again I have never tried this... I don't think Firestarter
is likely to know about serial interfaces, so I guess you would need to
hand-edit files to set up connection sharing.

Might be one place to look. Slip is pretty much obsolete AFAIK though, and
googling for howtos produces some arcane and archaeological results ;-)
