I've set up Port Forwarding on my router, but it seems, that it doesn' work. I've forwarded the port 25565 like this: (NAT Forwarding -> Virtual Servers)
25565 is the port for Minecraft servers. There's a server running on 192.168.1.109 and i can connect to it internally (In my local network), but not from the internet.
It's also not possible to ping the router from the internet. (https://whatismyipaddress.com/de/meine-ip to get my ip and ping with a Windows PC like "ping 12.345.678.910")
I tried to ping that IP from my own network and from another network, because a long time ago I had problems pinging my own internet ip address from the local network.
I thought, that this could be a firewall problem caused by the router, because some devices just don't allow ICMP, but I got the same result after disabling the firewall like this:
I hope you can help me with that issue.
BTW: Forwarding Port 22 (SFTP) isn't working, too.
