Unless I've misunderstood something, this won't work. If a machine on the LAN tries to reach one of the virtual machines (which is on a different subnet) it won't send out an ARP request for the IP in question, but just stick the MAC address of the the gateway onto the packet and let the gateway deal with it. AIUI proxy ARP is for when you have a subnet that's physically separated in which case the bridge will need to proxy the arp requests for hosts on the one side to hosts on the other side (and vice versa, obviously). -- Soren Hansen | Virtualisation specialist | Ubuntu Server Team Canonical Ltd. | http://www.ubuntu.com/
