are you sure it does masquerading both for 192.168.1.x and 192.168.2.x and
not just for 192.168.1.x?
I'm not sure, but i think the most basic masquerading setup does
masquerading of the local network for _all_ other hosts. And you have to
remember that a masqueraded host canot be pinged nor connected to in any
way! (as the name suggests, unless you have port forwarding rules to enable

I repeat, i know nothing about things specific to PLIP, but the only thing
that would change the situation seems to be some modification of routing
information. (read: i still suspect the masquerading - wasn't it when the
modem connected when the plip refused to work?)
Also: if A side of a PLIP link sees the B side but not the other way round,
it's not the fault of PLIP link. It's the routing information.
