So If I have my understanding correctly, I really DON'T need a
firewall in front of the Load Balancer, and site-to-site VPN
connection to the individual Web Servers, which have firewalls in
front of them as well, since:
#1 there are iptables anyways (firewall)
#2 the LVS has 2 Nics, with the 2nd nic connecting to the individual
firewalls via IP Tunneling.
#3 LVS-TUN is a form of protection anyways, because it creates a
secure tunnel to the individual web servers, and is used as those web
servers gateway.

If all this is true, my next step really, is to figure out how to
LVS-TUN, correct?
(I'm going to read up on the security aspect in the howto)
