-# WARNING!! When rules.{v4,v6} are changed, the whole iptables configuration is reloaded.
-# This creates issues with Docker, which injects its own configuration in iptables when it starts.
-# In practice, most (all?) containers will break if rules.{v4,v6} are changed,
-# and docker will have to be restared.
