How can I restrict access from external IP's for a ngnix location
Solution 1:
You should use nginx geo module for IP address maps. Your configuration would be like this with it:
geo $internal {
default 0;
127.0.0.0/8 1;
10.0.0.0/8 1;
172.16.0.0/20 1;
192.168.0.0/24 1;
}
location /app/sniper {
if ($internal != 1) {
return 403;
}
}
