white list 3 countries with Geoip instead of blocking all others

[tuatara]

Is it possible to white list 3 countries with Geoip in Intrusion Detection instead of blocking all others ?
It is for a Wordpress web shop that is only allowed to sell in 3 specific countries. 
And which receives a enormous amounts of cyber attacks from other countries

Dont use GeoIP in IDS, it's deprecated. Just use GeoIP Alias in Firewall aliases, there you'll achieve your goal
