i found this thread https://bitcointalksearch.org/topic/minera-access-from-internet-826572 that talks about wanting to view it from external, and is advised to forward https 443 port.
I have tried this on the local LAN and this port isnt open, is there a config i need to change to enable the port so i can forward it externally?
Just forward port 80 and you are done.
So this just opens my router to the internet which is port 80, how can i change the port of minera?
Forward another port for example 8080 (or 81) to the port 80 of Minera IP
Then you will access Minera by http://
