I'm trying to set up a simple SSH server, but the port is still filtered even after port forwarding. (I've set up SSH to use port 1338 instead of default 22.) We can see that the port is filtered by running a Nmap scan on the local IP (where the port is open) and then on the external IP. Running nmap on local IP:
Port Forwarding is a feature in routers by which external users are able to access a computer from a local network that is behind a router. This means that with this scheme, it is possible to communicate with a computer that is on a local network starting from anywhere in the world using the Internet. Port forwarding is the best way to preserve an IP address. It can protect both clients and servers from hacks and help improve your system – it is more commonly used to protect public IP addresses. Port forwarding can “hide” both services and servers on a network, but most importantly adds an extra layer of security to networks.

What is Port Forwarding? - What Is My IP Address Port forwarding, or tunneling, is the behind-the-scenes process of intercepting data traffic headed for a computer's IP/port combination and redirecting it to a different IP and/or port. A program that's running on the destination computer (host) usually causes the redirection, but sometimes it can also be an intermediate hardware component Solved: I can't port forward - NETGEAR Communities Note: Some port testing services can actually listen to the port and respond to requests, provided that you initiate the test on the device that you are port forwarding towards. It's important to understand that there is a subtle but important distinction when a testing service reports that a port …
In a typical network the router has the public IP address and computers/servers obtain a private IP address from the router that is not addressable from outside the network. When you forward a specific port on your router, you are telling your router where to direct traffic for that port. This utility can verify the success of that process.
