Hi Alessandro,

You'll need to change your LinearIPLookup to have three outputs, one for
eth1, one for eth2, and one for the router itself. Change the routing table
to emit packets destined for the router onto the new output. Then send
packets from that output to a ToHost element. But ToHost takes Ethernet
packets, so cook up a fake Ethernet header, like so:


  rt[0] -> EtherEncap(0x0800, 1:1:1:1:1:1, 2:2:2:2:2:2) -> tol;


Check out the output of make-ip-conf.pl for more hints.
