I have a box that is working as a router, and all it took was setting 
the routes correctly and then a:

echo 1 > /proc/sys/net/ipv4/ip_forward


I'm pretty confident that would be the same for the ppp interfaces as 
well. As long as the routes are set correctly, that is all it should take.


Peace.
