just think of this: how a client request is going to get anywhere? (there's no
"same" nic for an initial client request).
IP forwarding is only used for packets received from _foreign_ hosts and
destined to
_foreign_ hosts. it is enabled if the host acts as router and disabled
otherwise.
ipforwarding has nothing to do with packets originaed on the host itself.
if a route is not
already known, it is determined by checkng the routing table, using the IP
destination
address as a key. once the route is found, the corresponding interface is
used to send the
packet.
