Cannot access Apache web server from Wan side, only Lan side.

I have installed WAMPSERVER 2.0 on my windows vista x64 system but still am having issues with getting the webserver to be seen outside my local network. It is working fine within my local network.

Been through several setup tutorials so far, no dice still.

For testing purposes I have disabled my firewalls on my windows OS and on my router completely. They are turned off.

I have changed my httpd.conf file to the following (Allow from all):

    # 
    # AllowOverride controls what directives may be placed in .htaccess files. 
    # It can be "All", "None", or any combination of the keywords: 
    #   Options FileInfo AuthConfig Limit 
    # 
    AllowOverride all 
 
    # 
    # Controls who can get stuff from this server. 
    # 
 
#   onlineoffline tag - don't remove 
    Order Deny,Allow 
    Allow from all 
    Allow from 127.0.0.1 
 
</Directory> 
 
# 
# DirectoryIndex: sets the file that Apache will serve if a directory 
# is requested. 
 
I have set up port range forwarding to the IP address of the computer on my lan that has the Apache server on it.

I also turned on the WAMPSERVER and made sure all services are running. 
 
So:

http://mylanipaddress - No problems from any computer on the lan.
http://mywanipaddress - No problems from any computer on the lan but when any computer wan side tries to access this they still get a the server is busy or down message.

What am I missing? I can access the webserver from the computer the webserver is on but not from outside the lan.

Is this on a home network?

Your webserver have a public IP?

Is port 80 Nat'd through your firewall?

Is your ISP blocking port 80 traffic?

All things to consider!
