Raspberry Pi Minecraft Server Port Sharing?

Hi, I have a Minecraft server running on my Rasberry Pi, which so far only runs locally. Since I want friends to be able to play along, I have to release port 25565. I'm on Fritz.Box and have selected the following under port sharing:

Unfortunately that didn't work. Could someone help me please?

Did you choose the Rapsy as a device for port sharing?

Yes the rasberry and its ip

First of all, delete the UDP shares, they are nonsensical…

your external IP, can it be reached? Or do you also suffer from DS-Lite?

can your friends access over the IPv6? Enter the IP in square brackets…

You would only have to enable IPv4.

You also need to make sure your firewall allows this.

Thank you.
