I need some help regarding my private Ubuntu server. I recently bought a Raspberry Pi 4B. I decided that it was best to turn it into a server with the latest version of Ubuntu server.
I haven't attached a keyboard, mouse or monitor to the Pi as i was planning to only get access to the server with SSH. Now, I can SSH into my Pi when I'm on the same network, but for some reason I don't get access when I'm on a different network. Every time i try to connect from a different network it get the Connection timed out error. If I ping the IP address I get really fast response time, that's why this doesn't make sense to me
I checked the status of SSH with ~$ systemctl status ssh and it does say that SSH is active and running.
I found my IP address with ~$ curl ipv4.icanhazip.com. I checked the online devices in the dashboard of my router and it does say that it's connected.
OpenSSH server is installed and running. I checked and the firewall is not active.
I hope someone can help me out.
Kind regards,

By logging in successfully on your LAN, you have conclusively demonstrated that your Pi+Ubuntu server is configured properly.
All of the devices on your network share a single public IP address -- the router's IP address.
When you try to ssh into your network from outside, those packets reach the router first. Set up port forwarding on your router, so the router knows that the ssh connections should be sent (forwarded) to the Pi.
It's a router setting that has nothing to do with the Pi or with Ubuntu, nor with the Ubunbtu Server's firewall.
