the ":80" are ignored in the last two lines, since you can't
redirect ports with LVS-Tun.

This isn't going to get you exactly what you want. Since you
only have one VIP on the realserver, then there is only one
instance of the server running on it. The director will send
ipip packets to both x.x.x.200 and x.x.x.124, but both
streams will arrive at the lo==VIP.
I can't see how to do what you want with LVS-Tun. You can do
it with LVS-NAT.

the service has to listen on the VIP, not the RIPs. The
client is sending its requests to the VIP.
