Sorry for the delay in my response, things keeping me busy.
Anyway, I went in and tried it without the port forwarding and it worked, then I turned it back on and it still worked. I don't know why. *shrugs*
In the end though, I decided to us WAMP instead of IIS, for me it's easier to configure. Thanks for the response though, I wanted to be able to do it in IIS incase I need to later on.
