The remote cPanel webserver will return one public IP for each non-loopback IP that is sent. The list of the public IPs that are associated with the internal IPs will be written to the I file one mapping per line: local_ip remote_ip =over =item * Lines in I with only one IP will be ignored by cPanel/WHM because they are determined to not be publically accessible. =item * If multipe internal IPs match the same public IP, the first internal IP listed in the I file will be used. =back By default, this script will use the L URL to detect the public IP addresses that correspond to your local IP addresses. If you wish to override this URL, you can add an entry to the I file corresponding to the 'MYIP' key (example below): MYIP=http://myip.cpanel.net/v1.0/ NOTE: This URL must return B the IP address of the client connection. =cut
