Ports used by CentOS Web Panel

The main ports to access the CentOS Web Panel are 2030 and 2031.  Lately, CentOS Web Panel also uses ports 2086/2087 and 2082/2083 (similar to WHM). To summarize:

CentOS Web Admin Panel interface2030 or 2086
CentOS Web Admin Panel secure interface2031 or 2087
CentOS Web User Panel interface2082
CentOS Web User Panel secure interface2083

These ports are configured in the file /usr/local/cwpsrv/conf/cwpsrv.conf . You can check this file via command line with a utility like nano, or via the CentOS Web Panel File Manager. The contents of the cwpsrv.conf file is:

        }
    }
    include /usr/local/cwpsrv/conf.d/*.conf;
}

To redirect the non-secure ports to secure ports add the following lines to the file /usr/local/apache/htdocs/.htaccess

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

CentOS Web Panel uses the standard ports for services like the email server, SSH etc. :

SSH22
FTP21
SMTP25/26
Secure SMTP465
POP3110
Secure POP3995
MySQL3306
IMAP143
Secure IMAP993
HTTP/HTTPS80/443

    Hello,
    We don’t have a CWP server at this time, but I doubt you can change this from the interface. Please ask on CWP forums.
    Thanks.
