For now I am reading that to try to get familiar with the topic:

I found the firewall settings when I browse into my machine but cannot figure out what to change.
If you have any tutorial or some clue about which information to google about that matter that would be helpful.
I changed password of the miner as a first try, but it didnt solve anything
