Hi there,

I have a simple L4 Director setup with multiple real network interface
(eth0, eht1, and eth2) my real servers only have access to the director
through its eth1 <IP> interface.

When I create a simple rule (L4 NAT (masquerading) pointing to all my
reals) it does the NAT using the eth0 as the source ip to the real. Now my

How does the ipvs choose which ip / network interface to be its SNAT to the
reals? (the first one eth0)
Can I induce/setup it to pick a specific one? (like eth1)

Thank you very much
