Hello,

How do I open up the router to the public Internet? Like is there a way to configure this? Am I able to open up ports or such?

Thank you for your time and consideration.

Best regards,

Can you explain you setup in a bit more detail?
I am sharing a cellular connection (SixFab SIM) to my router via Ethernet.
