I don't know where the packets are coming from either. But see below.

Have you tried the routed network configuration? That should avoid the
problem of spoofed MAC addresses, since it doesn't use the bridging
code, and should configure Dom-0 to use proxy ARP so that all your IP
addresses will be accessible to the outside using your original MAC
address.
