How to do Port Forwarding in Netgear Router

What is Port Forwarding?

Port forwarding or port mapping is the technique to route all inbound traffic on a particular source port to one host on a network. For ex if we want to forward all incoming request on Port Number 80 to 192.168.1.100(LAN IP Address) and all incoming request on Port number 81 to 192.168.1.200(LAN IP Address) then we need to tell router to do this routing.

How to setup Port Forwarding?

Basic Requirements?

1. We need a Router that support Port Forwarding. Like NETGEAR Router JWNR2000v2 
2. Admin access to Router Control Panel. By default its http://192.168.1.1 (Username: admin Password: password)
3. That's it

Step 1. Using any PC connected to LAN(Local Network), we open browser and type router IP in address bar e.g. http://192.168.1.1 (Default Router IP)

Step 2. Login popup will appear. Type Username and Password of Router (Username: admin, Password: password)

Step 3. Click on Port Forwarding/Port Triggering

Step 4. Click on Add Custom Service Button at the bottom of page, Enter Following 

Service name = "HTTP" 

Service Type = ""TCP/UDP"

External Port = "80" (In this Example)

Internal Port = "80" (Same as External)

Internal IP = "192.168.1.100" (IP address of local machine to which we are forwarding port 80)

Click on apply.

That's it

Now all inbound requests on Port 80 will Forwarded to Internal IP "192.168.1.100"
