title: Actiontec Port Forwarding Configuration - Start/End ports for External (WAN) and Internal (LAN) options
body: <p>Looking for some clarification as to the differences between the "start" and "end" port settings on my router, for the purposes of <strong>port forwarding</strong>.</p>
  
  <p>I don't have enough 'reputation' to post a picture of my router port forwarding configuration page ...</p>
  
  <p>So I'll type up exactly what it looks like here:</p>
  
  <p><strong>Port Forwarding</strong></p>
  
  <p><strong>1. Set the LAN/WAN port and IP information.</strong></p>
  
  <p>Select LAN device: </p>
  
  <p>LAN IP Address:</p>
  
  <p>External (WAN) Start Port:</p>
  
  <p>External (WAN) End Port:</p>
  
  <p>Internal (LAN) Start Port:</p>
  
  <p>Internal (LAN) End Port: </p>
  
  <p>Protocol: (options: TCP, UDP, GRE)</p>
  
  <p>That's it.</p>
  
  <p>So, hypothetically, if I wanted to open up a home-based web server for users outside my LAN on port 80, would "80" be filled in for all the port options? What are the differences?</p>
