The port to run an authentication proxy on is typically port 80 or 443. This is because these ports are commonly used for web traffic, and authentication proxies often handle user authentication for web applications.
However, the specific port used can vary depending on several factors, including:
- Configuration of the proxy: Some authentication proxies allow you to configure the port they listen on.
- Security considerations: Using a different port can enhance security by making it more difficult for attackers to target the proxy.
- Existing infrastructure: If other services are already using ports 80 and 443, you may need to choose a different port.
Here are some examples of common ports used for authentication proxies:
- Port 80: Used for standard HTTP traffic.
- Port 443: Used for HTTPS traffic, which is encrypted.
- Port 3000: Often used for development environments.
- Other ports: You can choose any port that is not already in use on your system.
It's important to choose a port that is appropriate for your specific needs and environment.
