I use the term redirect loosely. Not all realservers behind each director
require load-balancing since there may only be a single server for that
function. I say redirect to mean that LVS has only a single realserver for
that service. I am basicaly using LVS to NAT to my realservers in that
situation so I dont have NAT on my router and NAT on the directors. I know I
could NAT these with iptables but it is more convenient to just use the
director and lvsadmin.
