Hello, I currently am working in an environment with 3 NIC operating in bridged mode with XEN. The two cards configured with static ip addressing are working properly in XEN DomU guests, and Dom0. However, there is one interface that connects upstream to my ISP, which has IP addressing based on DHCP. The DomU in question has all three network cards bridged to it, and two of them work, but the the WAN uplink does not. `brctl show` on the Dom0 shows that the DomU is connected to the correct bridge. Is it possible to rewrite the MAC address on Dom0 to a MAC address that the ISP would assign an IP too (I'm assuming it's rejecting the XEN MAC at this point)?
