[Planetlab-users] Setting: ip_forward

[Vivek Pai]

I'm not a planetlab developer, but I believe
that's a system-wide setting that would affect
everyone on the node, since everyone shares the
same IP address.

PlanetLab does have safe raw sockets, which only
allow you to see data for your slice. Using that
and your own application-level stack, you should
be able to build a custom router.
