thanks for your reply! Your solution does indeed make sense and I've been using something similar before. Just thought there might be something that wouldn't require rewriting my current syntax, such as:
if ($geoip_country_code ~ (BR|CN|KR|RU) ) {
if ($remote_addr = (1.2.3.4|1.2.3.5|1.2.3.6) ) {
break;
}
return 123;
}
