# every docker service restart.
# And just doing an iptables-restore is going to mess up kubernetes'
# NAT table.
# And it gets even better with openshift! It thinks I'm stupid and need
# to be corrected by automatically adding the "allow all" rules back at
# the top as soon as I remove them.
# To circumvent that, we're just adding a new chain for this, as it seems
# that it doesn't do anything with the firewall if we keep its rules in
# place. (it doesn't check the order of its rules, only that they exist)
