I want to thank Gladson Jacob for the response. I am actually getting the internet access now with the following: http://lgcnjcom.w12.wh-2.com/page/3?returnurl=%252f

the three url in install:

1 internal Address

2 External Address

 3  Organization website

I was not clear where to update these settings: Administration->General Settings

should it be Administration -> General Settings -> Global Attributes

Also, The list in Global Attributes has:

Internal Application Root     is this the same as 1 internal address?

 Publica Application Root      is this the same as  2  External Address?

 

I changed the A record in the server as adding follows:  

 http://rock.Igcnj.com

What updates should I perform in General Settings for internet access?
