For example, we could configure a rule that says: any traffic received using port number 3389, forward that traffic to our computer, which has the local IP address 192.168.1.10 If our router were to receive a request with that destination port number, it would look at the IP address, think, “Yes, that’s me,” and then look at the port number. The router will check its port forwarding rules and forward that request to our computer. So, the traffic is forwarded based on the port number, hence the name port forwarding. While this is pretty simple to set up, it can be risky. Any ports you open to the Internet will likely be attacked. Keeping everything secure is very important when using port forwarding. 00:00 Into to Port Forwarding 00:22 A better way 01:38 What are ports? 04:04 Public and private networks 04:44 How port forwarding works 06:14 How to configure port forwarding 10:41 Security risks 12:19 How to secure open ports 13:14 Summary
