Access cPanel from behind Corporate Firewall
For clients using cPanel and surfing through a corporate firewall, you may find that you are unable to view your cPanel because the standard Port 2082 is blocked by the firewall.
If this is the case, cPanel Proxy lets access to your cPanel (including your webmail) at port 80 by acting like a proxy.
You will need to download cPanel Proxy and create a subdomain "cpanel.yourdomain.com" . After downloading, unzip the files and upload into the subdomain folder.
Make sure you upload both the cpanelproxy.php .htaccess php.ini files. Please follow the steps in our FAQ centre if you need further instructions.
