Yes but the patch mentioned there is from 2001 and the bridging approach 
has a lot to say about network theory but doesn't provide a specific 
example how to configure such a setup.
What I'm looking for is a way to tell the gateway to not throw away these 
martian packets. Something along the lines of "iptables -t nat -A 
PREROUTING -s $vip -j DISABLE-MARTIAN-CHECK".
