Certainally, in drawing 'a' the virtual server has two interfaces, and
eth0 would be the external interface, and eth1 would be its internal
pool of servers. I just wondered if the servers had to be on a seperate
network to avoid confusion with clients or other server pools.
Drawing b hows both the vertual server and cluster computers on the same
network.
