Three questions:
--can LVS be used as a combined load balancer/firewall, since you're using
ipchains already, or is ipchains on a separate box recommended?
--can you place a single box that *doesn't* need load balancing behind the
LVS box? Not sure how would work, if the LVS box always represents just one
IP.
--is LVS a good choice for the following configuration?
Requirements: 3 webservers, need to be load balanced; 1 database server, not
part of the load-balancing cluster; all servers are colo and need to be
firewalled and accessed remotely

This diagram is just a draft. If the LVS box can serve as a firewall and the
db box can go behind it, so much the better.
thanks!
