You should be able to handle reaching a gateway, on the same wire as you
but on a different (sub)network number, using the following awful kludge:

   Allocate a fake IP address on your own (sub)net for the remote gateway.
   On the local machine:  arp -s fake-gw-address gateway-Ether-address perm
   On the local machine:  route add  destination-net  fake-gw-address  1

and hope the "permanent" arp is never purged from the cache.
