+# Possibilities to limit access to webconsole by IP/subn
+
+All web console files start with `/static/`, all api start with `/api/`. If you use NGINX, you can write some NGINX rule to limit what you want.
+
+e.g.
+
+```
+     location /static/ {
+         allow 192.168.1.0/24;    # Your office network
+         allow 10.0.0.0/8;        # Private networks  
+         allow YOUR.HOME.IP.HERE; # Your home IP
+         deny all;
+
+         proxy_pass http://127.0.0.1:21114;
+         proxy_set_header Host $host;
+         proxy_set_header X-Real-IP $remote_addr;
+     }
+```
