Let me guess, you are using LVS DR and have real servers running on the
directors as well.

The solution is to define your VIPs as FW marks rather than simple
IP:port. In your iptable rule you can so exclude the packets originating
from the other director (based on MAC) to be flagged with the right mark.

If it's not the case, please describe a bit more your configuration so
we can help.
