Hello,
I am not familiar to this *.conf scripts, but will try to verify it for
you.
For the network topology that you give, it should work with the IP-TUN,
and DR methods (You don't need nat_lvs.conf here, otherwise you need turn
eth1 off at the backend servers). Maybe you need pay more attention to the
ARP problem if you are running Linux on the backend servers, see
http://www.linux-vs.org/docs/arp.html for more information.
Let us know if you meet any problems in setting up your LVS cluster.
Good luck,
Wensong
