You're misunderstanding a fact: if tap0 receives a packet with its IP, it's for the host; so tap0 should have IP A. To send a packet to IP B (UML) IP B must be the destination address (set inside UML), not the source address (set on tap0). If UML sends a packet to IP A, it will go to host tap0; if anybody else sends a packet to IP A, it will arrive to host eth0. The fact that UML has IP B is set via proxy ARP. If you use uml_net, it's done automatically, otherwise you do it by hand via proxy ARP, see the site "Virtual Networking" page. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
