you set the forwarding type separately for each RS.
setup 1-4 with DR and 5-6 with Tun.

I'm using mon. Other people seem to be using ldirectord.
In mon you have commands like
if service on machine x is down, then remove machine x from ipvsadm table

If machine x comes back on line, you can remove machine y.
