You’re gonna want to configure nginx to send along an X-Forwarded-For HTTP header (there’s also Forwarded, but it’s not as well supported yet). An example in a location block:
location / {
proxy_pass http://backend/;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}






I really don’t know shit about the GUI tools, but presumably they overlay on the same configuration.
The config I posted would be part of the nginx configuration. You’re instructing it to append the client IP to the
X-Forwarded-Forheader.I doubt it, but I’m not sure. The
locationblock would normally be where your reverse proxy configuration would already be, and you’d need to just add that one line. But again, I don’t know how that translates to these GUI tools. Maybe if you search forproxy_add_x_forwarded_forand “Nginx Proxy Manager” you might find what you need.
