How to use Zenfirewall with nginx

The steps to add ZenFirewall IPs to your Nginx configuration are as follows:

1. Download the blocklist file and generate a configuration file suitable for Nginx. This command can be added to a cron job and executed once or twice per day:

   curl -sf https://zenfirewall.com/zenblock.txt | sed 's/^/deny /; s/$/;/' > /etc/nginx/blocked_ips.conf

2. Add the following configuration to /etc/nginx/nginx.conf inside the http block:

   geo $blocked_ip {
       default 0;
       include /etc/nginx/blocked_ips.conf;
   }

3. In each virtual host where you want to apply this list:

   server {
       listen 80;
       server_name test.com;
   
       if ($blocked_ip) {
           return 403;
       }
   
       location / {
           # xxxxx
       }
   }
