packets are still not being put on the physical
network.
The network code is smart and will spot traffic destined for the local
machine and avoid transmitting it over the ethernet. I discovered this
years ago when I wanted to do some testing without using a seperate box.
At the time I determined this was not possible (it was before Linux had a
firewall built in).
You could consider trying to NAT the traffic out on to the lan.
