Maybe someone can come up with a way of overcomming my dilema - it's just
a temporary thing, but I couldn't figure a way to do it.

I have a home machine and a laptop, both running FreeBSD.  My home machine
connects to the internet each night using a modem to an ISP and exchanges
email and news.  I have a news server on both machines, and when I connect
my laptop to my home machine, it exchanges email & news with it.  The
result is being able to do stuff off-line on my laptop, and then hop it
back to the internet through my home machine.

I am now in the US for a month, and would like to do the same thing.  The
problem is that I don't want to dial my home machine directly.  I can
connect my laptop to a WAN where one of the London machines has a modem
that can dial my home machine.

The problem is that the London machine supports neither slip or ppp.
Can anyone figure a way to get a packet to route from one end to the
other?  The diagram:

  --------------                ---------------           ----------
  |   Home     |----Serial------| London      |----IP-----| Laptop |
  --------------                ---------------           ----------

The Laptop <=> London link is transparent IP-wise.

TIA.
