=head1 NAME

build_cpnat - enables 1-to-1 NAT in cPanel/WHM.

=head1 SYNOPSIS

build_cpnat [options]

Options:
    --help        print help message

=head1 DESCRIPTION

1:1 NAT mapping

When /usr/local/cpanel/scripts/build_cpnat is executed, all non-loopback IPs
bound to any network interface on the system will be used to make a connection
to a remote cPanel webserver. 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</var/cpanel/cpnat>
file one mapping per line: local_ip remote_ip

=over

=item * Lines in I</var/cpanel/cpnat> 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</var/cpanel/cpnat> file will be used.

=back

By default, this script will use the L<http://myip.cpanel.net/v1.0/> 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</etc/cpsources.conf> file
corresponding to the 'MYIP' key (example below):

MYIP=http://myip.cpanel.net/v1.0/

NOTE: This URL must return B<only> the IP address of the client connection.
