Ok. Windows does just the same. Thanks for the ARP table. [For ML
readers - it was sent directly]. Now we know what the money are paid for :)

Quite possible with the invalulable help of Nux:
Parprouted + NetworkManager scripting should do the trick.

Try the aforementioned unnumbered option first. Can't say anything about
IPv6 - sadly not proficient. For IPv4 you won't need iptables, only iproute:
1)save and delete the current wireless default gateway IP
2)create a source-based policy routing rule so traffic from the fw VM IP
address would have the earlier saved IP as a gateway IP
3)set the default gateway IP to the another interface's (it's a
requirement) IP address of a fw VM.
