Ah, yes, ipvsadm, had forgotten that, or I'm sure the man page would
have given me the rest (downside of using web-based config, I don't
learn the local tools as well). I do need to MASQ traffic originating
in the private network, the services running there have to connect out
to get to the database, and since the default route on those boxes
points to the load-balancer to make LVS work.

That'd be exciting :-).
