Enable cPanel port via SnapGar SG300 router

[zillah]

Hi

I am able to access a cPanel of my domain from home and friend's house ,,,,means there are two different types of routers.

Neither me nor my friend has enabled port 2082 via router's firewall,,,,I do not why !!!!

At work I tried to access cPanel (using Mozilla and IE) of my domain by typing in this :

http://fakedomain.org.au/cpanel

Error message : page not found.

Our work's domain is hosted with a web hosting provider not on our work's server

through my google search I found below nice tutorial and I tried to configure my SnapGear router SG300 similar to it, but no joy

This is what I did
