# The following example shows a way to use iptables for basic round-robin load balancing, by redirecting
# packets two one of three ports based on a statistic counter.
#
# TCP packets for new sessions arriving on port 9000 will rotate between ports 9001, 9002 and 9003, where
# three identical copies of some application are expected to be listening.
#
# Packets that aren't TCP or that related to an already-established connection are left untouched, letting
# the standard iptables connection tracking machinery send it to the appropriate port.
#
# For this to work well, connections need to be relatively short. Ideally there would be an extra layer
