[OT?] Loadbalancer on Debian

[Niclas Söderlund <lists@soderlund.org>]

Hi all.

Im searching for a free alternative to byuing an expensive loadbalancer 
appliance. I have two identical servers on the "inside" and need third 
machine on the "outside" doing a round-robin of a couple of ports to the 
two servers on the inside, keeping states and such so that the traffic 
is flowing unhindered and that new connections are established in equal 
numbers to the two servers.

Is this possible with Debian and if so, what application does this?

TIA,

N
