GeoIP2
Download and install the GeoIP database from Maxmind.
This one is a free and lite version of the database
You will need to download the 'Country' .mmdb file for either the paid or the free one
This file needs to be on your NATS installation in a path that is accessible to NATS The path will need to be specified in config->surfer->tracking GEOIP2_PHP_DATABASE_LOCATION
You will then switch the IP_FILTER to GeoIP2_PHP and store your changes
Test Code
The following PHP code will help you test GeoIP. Put it in a file, put the file on your webserver, and load its URL. It should print your country's name.
<?php
include_once('../vendor_includes/geoip2.phar');
$reader = new GeoIp2\Database\Reader('<PATH_TO_DB_FILE.mmdb>');
$record = $reader->country($_SERVER['REMOTE_ADDR']);
$country = $record->country->isoCode;
echo"$country is country";
Note: Please be sure to perform this test after you install or update Maxmind's GeoIP.
Optional Extension
As stated in their docs: "[This extension] dramatically increase the performance of lookups in GeoIP2 or GeoLite2 databases"
Download this as either standalone or via composer.
Then download this and follow the instructions on the site to configure this library. (Note you will need to have a compiler such as GCC installed on your server).
$ ./configure $ make $ make check $ sudo make install $ sudo ldconfig
Once the two packages are installed, you will want to run the commands in the "Installing Extension" section
cd ext phpize ./configure make make test sudo make install
Finally, add "extension=maxminddb.so" to your php.ini file and restart PHP
