Off the top of my head, having not much experience with LVS and UDP,
yes. It should work the same way as TCP (more or less).
If you are expecing the datagrams from a given CIP to be directed to
different ports, and you want these datagrams directed to the
_same_ real server, then you should use firewall marks. Otherwies,
a normal port/ip service should suffice (though a firewall mark will
work in this case too).
