The problem is you no longer see it, once you are on a different LAN. 
The packets from *your* machine will have the MAC address of *my*

That's just like forwarding -- it's _forgery_ when _your_ router sends
packets with _my_ IP address. It's _my_ IP address, and it's my right to
demand that you stop forging it. Your router needs to use NAT.
