I get along fine from home to/from work via ppp without the need for a
third network for ppp. You'll need to add "proxy" to the ppp
configuration (SCO PPP). For example, work is 192.168.1. & home is
192.168.37. :

home side:
# grep icg /etc/ppphosts
icg-thor:thor-icg uucp=icgppp accm=0 mask=255.255.255.0 filter=thor

ts proxy mru=1536
*ideacom local=thor-icg remote=icg-thor accm=0 filter=thor flow=rtscts

mru=1536
# ifconfig ppp0
ppp0: flags=4071<UP,POINTOPOINT,WANTIOCTLS,RUNNING,MULTICAST> mtu 1536

>From home I can ping every PC, printer, diskless workstation
(www.ltsp.org) or ethernet terminal at work and from work, everything at
home.
