Port forwarding is when we tell our router where to send a request based on the port number within the message.
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.

Subscribed, sir! This is great stuff.
Thank you! Happy you enjoyed the video.
someone can explain to me, how I can find out the target ip and port?
4:32 If I am controlling outbound traffic from the client on the FW, how should I allow the passive data transfer method? It seems like it is a random high port selection.
