Load balancing advice is needed

[Artur Shnayder]

  Hi All,

  We have multiple embedded boxes running web servers in development
environment. For performance benefits I'd like to install some kind of load
balancing based on Linux. Round robin DNS can't be used for some reason.
Load balancer and web servers are located in single network. It seems
iptables -DNAT option can't be used in this case.
 Any idea would be really appreciated.

 Thanks a lot,

 Artur
