Just specify the PPP users Class C with netmask 255.255.255.255 in the
netmask table. This setups 1 host networks so that host routes will be
broadcast. You may also have to add a route for all traffic destined for
your internal network in the second PM, using a gateway of the address of
the second PM. We have a couple of PM's and 5 class C's and this works fine.
