What is Port Forwarding?
  • In Computer Networking, Port Forwarding Or Port Mapping Is An Application Of Network Address Translation (NAT) 
  • That Redirects A Communication Request From One Address And Port Number Combination To Another While The Packets Are Traversing A Network Gateway, Such As A Router Or Firewall.

What Are Ports?
  • Ports Are Virtual Pathways On Which Information On The Internet Travel. There Are 65,536 Ports To Choose From. 
  • A Good Analogy Is To Think Of Ports Like Extensions On A Phone System.

What Are Some Commonly Used Ports?
  • Every Program On Your Computer That Uses The Internet Is Programmed To Send Its Packets Through Specific Ports. 
  • Sometimes the Ports Are Selected Arbitrarily By the Programmers of the Software,

Here Are A Few Examples Of Industry Standard Uses For Common Ports:
  • HTML Pages: Port 80
