Boris Djurdjevic 8bcd166c4c Fix connection resets during firewall sync (#807)
For very busy tcp connections there is a small possibility to receive
a TCP RST during the iptables sync.

A default `REJECT` rule is chronologically added before the allow-`RELATED,ESTABLISHED` rule for ingress and
egress connections.
In between of the creation of these two rules a connection reset can happen for already established connections.

This commits swaps the order of rule insertion.
