One documentation I read guided you to first set up a test portforward (8123 → 8123) and later on advices you to delete that portforwarding and replace it with (443 → 8123).
Currently I can’t find that doc.
Whats the reason for this?
Is it more unsecure to open the port 8123 to the public than opening 443?
The advantage about the forwarding 8123 to 8123 is that it will be the same URL either in the local or in the public network.
When I change it to 443 → 8123 than I have to open XXX.duckdns.org in a public network and XXX.duckdns.org:8123 in my local network. Or is there a workarround for that?
So it makes no difference (thats my main question) if you chose 443 or 8123 than why use different ports?
EDIT:
This is the doc I was talking about.
headlines 5 - CHECK THE INCOMING CONNECTION and 6 - CLEAN UP PORT FORWARDS
In step 2 we created a port forwarding rule called
ha_test. This opens port 8123 to the world, and is no longer necessary.
