patch from Yuval Yarom, sent to me by <andrew@werple.apana.org.au> 

The check that the destination of a forwarded ip packet is not on
the loopback net is wrong, and will always fail.  The following patch
fixes the problem.
[allows "route add $hostname localhost" to be added to /etc/netstart to
keep things for $hostname away from the ethernet driver]
