Withing integration issues with port 443 vs 8123

I request iptables be added to home assistant along with away to save and restore the rules automatically before home assistant is fully loaded. I usually create a systemd entry to automate this.

iptables

Due to a withings call back I need to redirect port 443 to 8123. This is the simplest way to do this.
Has the fewest dependencies and etc.

Is there another easier way?
