Core Features

Key Features of Nginx Proxy Manager

• Simple UI: An intuitive web interface that makes it easy to manage proxies and SSL certificates.
• SSL Management: Automatic SSL certificate generation and renewal using Let’s Encrypt.
• Access Control: Basic HTTP authentication for services.
• Custom Domains: Easily assign custom domains to your services.
• Multiple Users: Support for multiple users with different access levels.
• Docker Support: Easy deployment using Docker.

Use Cases

Nginx Proxy Manager is incredibly versatile and can be used in a variety of scenarios. Here are some practical applications:

Example 1: Simplified SSL Management for Web Services

Imagine you are running a web server, a media server, and a database server in your homelab. Managing SSL certificates for each service can be a nightmare. With NPM, you can centralize SSL management, automatically generating and renewing certificates for all your services.

Example 2: Securing Internal Services with HTTP Authentication

If you have services that you want to keep private, such as an internal dashboard or an admin panel, NPM allows you to set up basic HTTP authentication, adding an extra layer of security.

Community insights often highlight the ease of use and the reduction in manual configuration as significant advantages of using NPM in these scenarios.

2. Immediately change the default admin password for security purposes.
3. Navigate to the ‘Hosts’ tab and click ‘Proxy Hosts’ to add a new proxy host.
4. Fill in the details for your service, including the domain name, scheme (http or https), and forwarding hostname/IP and port.
5. Enable SSL and select ‘Request a new SSL certificate’ to secure your service with Let’s Encrypt.

Advanced Configuration

For advanced users, NPM offers a range of customization options:

• Custom Nginx Configurations: Add custom Nginx directives to fine-tune proxy behavior.
• Access Lists: Create access lists to restrict access to certain services based on IP addresses.
• Advanced SSL Settings: Configure SSL protocols and ciphers for enhanced security.

Usage and Performance

Using Nginx Proxy Manager is straightforward once configured. Here are some real-world examples:
