Sorted it now works. I did have to open up my ports on the router. Also had to restart the server.
Now from outside my website is displayed straight from typing in the purchased domain name.
Lubos, I checked those IP Address that you pointed me towards and they were fine already.
Thank you to both of you for your help and perserverance with me, hopefully this topic will come in handy for someone else who is trying to do the same thing as me.
All I have got to do now is to get it to show my webpages when I open a browser that is connected to my LAN rather than showing me the router page.
