IPS GeoIP Blocking
|
|
==================
|
|
|
|
This tutorial explains how to setup the IPS system to block IPs based on their
|
|
geographic location. This option is made possible by the integration of the
|
|
Maxmind GeoLite2 Country database. More information can be found here: http://dev.maxmind.com/geoip/geoip2/geolite2/
