Now you need to configure Apache VirtualHost.

To block traffic, add following to your VirtualHost entry

RewriteEngine On
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(CN|RU|A1)$
RewriteRule ^(.*)$ https://serverok.in [L]

RewriteEngine On

RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(CN|RU|A1)$

RewriteRule ^(.*)$ https://serverok.in [L]

In this example, traffic from CN, RU and A1 (stands for proxy IP) get redirected to specified URL.
