That is correct. See, ppp is a point-to-point protocol, so traffic can only
go in two directions anyway, so you can tell ppp not to use any kind of
layer 3 routing and just send packets to the other side automatically.

In Linux you do that by just specifying local_ip:remote_ip on the server
side and : on the client side.

Ok, so this (otoh so don't blame me if it doesn't work *g*) in your inittab
should do the job:

------------< snip <------< snip <------< snip <------------
# At office
S0:23:respawn:/usr/sbin/pppd /dev/ttyS0 115200 modem noauth crtscts persist \
192.168.1.10:192.168.2.10 nodetach >>/var/log/leased.log

# At home
S0:23:respawn:/usr/sbin/pppd /dev/ttyS0 115200 noauth lock debug crtscts
defaultroute persist nodetach >>/var/log/leased.log
------------< snip <------< snip <------< snip <------------
