I believe the route command is used to identify/control
which interface to use to reach a particular host/network
[and which one(s) to handoff to in the default case(s)] for
connections originating on the machine in question.  I believe
that's distinct from forwarding, which determines whether/how
inbound traffic destined for other hosts/networks is handled,
and is managed by manipulating /proc/sys/net/ipv4/ip_forward
and friends via the sysctl command.
