How I (IT noob) Portforwarded on my Huawei echolife HG 521 router

[Gohar]

SET STATIC IP ADDRESS
I used these instructions: http://corz.org/comms/hardware/router/static.ip.address.php 
It was previously set to find IP address automatically, and as per link instructions, i entered them manually

ALLOW MULE/PORT 6260 TO BYPASS YOUR WINDOWS FIREWALL
control panal --> windows firewall --> advanced settings --> inbound rules --> new rule --> port --> specify port 6260 and apply to TCP --> allow connections --> tick private and public --> finish

Repeat above but instead of TCP select UDP

PORT FORWARDING
Went to "web interface" by typing router address in browser's address bar.
My router address was 192.168.1.1.  It is so for most people.

Logged into my router using my password (in my case, admin, admin)

Went to NAT settings, and chose the "portmapping" tab.

In there I chose the "customization" bubble (as opposed to the application" bubble.

My settings:

Protocol: TCP/UDP
Remote host: Leave blank
External start port: 6260
Internal end port: 6260
Internal host: Your computers/laptops IP address (in my case 192.168.1.10)
Mapping name: Whatever you want apparently. Just a reference.



And then i saved the settings and hey presto it all worked.
