- Open httpd.conf file in your host.
- Find Listen 80 and on the next line add Listen 8080
- Find VirtualHost section for your Site config.
- Add *:8080. It should look like this: <VirtualHost *:80 *:8080>
- Restart Apache
- Test your work by hitting your site to the new port number. Example: http://www.yoursite.com:8080
This would be helpful for you if your ISP is blocking any port. You can add an alternate port in your website. Here we have used port 8080 but you are free to use any other.
