Description of Issue

Hello, like many I’m struggling to get the port forwarding thing work for me. I’ve read the instructions and the topics on fritzbox. This post https://community.roonlabs.com/t/port-forwarding-instructions-for-most-fritz-box-users/212491 seemed the ultimate and super simple solution. Unfortunately the topic is already closed, so I cannot reply to it directly.
I tried it and it worked. But something is not clear and makes me nervous.
I thought that the idea behind port forwarding was to open a specific item on your home network to a very specific machine or service on the internet. That way it’s reasonably safe. If the service is not recognized the port will not be opened. At least that’s how I assume it should be working.
Following the instructions I open my roon core to the internet. But I can’t see any limitation to who can connect to my network. In other words, it’s wide open.
Or am I missing something?
The problem is that I haven’t got a clue what I am doing. I just click where I am pointed. That’s a potential highway to disaster. For the time being I’ll stick to apple music or qobuz when out.
I hope someone can shed some light

Perhaps these messages from Danny will shed some light on what is happening. Bottom line: unless you’re paranoid, you can relax.


Thanks Geoff,

Yes. My paranoia is caused by a lack of knowledge combined with an overflow of information.
I’ve read the posts you referred to before. I read it again, now understand them better.
I’ll give it a try.

Thanks again
