Because of the nature of UDP, unless you've got two listening UDP
ports, the ppp -direct side will end up with just one link talking to
the two links on the client side. This is immensely confusing (it
took me some time to figure out why it works.. and I wrote it!), and
it is also why ppp -direct doesn't insist on the recvfrom()s all
coming from the same peer sockaddr....
