[Sunhelp] Confused about routing.

[Rob Staab]

ndd -set /dev/ip ip_forwarding 1

Will turn IP forwarding on between Sun interfaces. This can be made
permanent by editing the /etc/init.d/inetinit startup script.

I believe this is what you're looking for then. Sorry, the extra routing
information threw me.
