I tried clearing the masquerade table, then clients can't reach the
remote network. So the FC3 machine, with a connection to eth0 and ppp0,
plus set to act as a router, does not appear to act as a router between
eth0 and ppp0. 

Is it possible to make it be a router between eth0 and ppp0 without
masquerade? Just be a router....

Thanks,
