WampServer

Hello
I have a problem
My router doesnt allow port 80 to be open
So how can i change the port ?
for wamp :

Open up your httpd.conf file in a text editor (preferably NotePad).
C:\wamp\Apache2\conf\httpd.conf

Find this section in your httpd.conf:

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 80

Change Listen 80 to:

Listen 81

Now save the file, restart apache so the new settings take effect. Now you can access WAMP at:
[localhost]
