 Will do.

 Smeg. And there is no way around this ? I can't setup separate IPs & the
like on the LB, and use direct routing for those, and masq for IP's used
outside the cluster ?

 I'm really really curious why this doesn't work. So curious, that if
someone could give me a good reason, I'd devote a lot of time to making it
work, if possible.
