are you clear about the fact that real_ip is the real
IP of the real server? (the one that the LVS use to
connect to the real server :-) )

you should do this in each real server, so real_ip is
diferent for each real server
none of those IPs are IP bounded to an specific LVS
(master or slave), well vip is but is like a floating
ip :-)

I think you beleave that this "real_ip" is the IP
owned by the LVS to comunicate with the real server,
but it is not. The real_ip is the IP owned by the real
server, which is used by the LVS to connect to the
real server :-)
maybe a graphic is very needed :-)
just keep in mind what is purpose of the arptable
commands: avoid at all means that the real server
announce that it has the VIP as one of it address
