I recently created a minecraft server for me and my friends, I did everything according to Alex's tutorial including port forwarding, I did a dynamic ip with noip, I have a new router and i believe that on raspberry pi 4 there is not firewall that can get in the way of port forwarding, the local ip works, the public ip doesn't work for anyone I have really done everything but without finding a solution.
