If you don't see port 80 open and you have verified the forwarding rules are correct, your ISP might be blocking it.

It will be easier if you install webmin to manage the server. From there, you can change the apache server port to other number. Bear in mind that external access via http will require to add the new port number at the end of the url since it is not the standard http port number.

You would need to contact your ISP and ask. Generally most residential ISPs block port 80 and usually port 25 as well.
