That should be fine from an LVS point of view.
I am not sure about lvs_dr.conf.
In a nutshell, the following will work with all forwarding mechanisms
(including LVS-DR).
VIP:80 -> RIP:80
VIP:8080 -> RIP:8080
VIP:X -> RIP:X
This however, will only work if you use LVS-NAT.
VIP:80 -> RIP:8080
VIP:X -> RIP:Y
