Nginx Proxy Manager – Access List protection

How can you easily lock down proxy hosts on the Nginx Proxy Manager with Access List protection? I recently deployed many services in Docker containers that I’ve exposed via the Nginx Proxy Manager. But some of these services should not be accessible for everyone. Or you have specific applications that don’t have any user authentication and you want not everyone to access them. With a simple Access List in Nginx Proxy Manager, you can define a custom policy based on credentials or IP addresses. Let’s have a look at how that works.
