Configuring Nemesida WAF in reverse proxy mode | Nemesida WAF

To use a web server with filtering node as an intermediate server, you should create corresponding file of the virtual host (for example /etc/nginx/conf.d/example.com.conf).

Example of the virtual host file:

server {
        server_name  site.example.com;
        listen 80;

        location / {
                proxy_pass http://x.x.x.x;
                proxy_set_header        Host $http_host;
        }
}

where x.x.x.x is the address of destination server with the web application.

More information is available on the official page of the Nginx documentation.

To get the real IP address of the client by the filtering node, bring the configuration file of the upstream server (for example, the load balancing server) to the form:

http {
   ...
   set_real_ip_from x.x.x.x;
   ...
}

where x.x.x.x – the address of the upstream server.
