How do I set up a firewall for Nginx?

To set up a firewall for Nginx, you can use tools like UFW or iptables. Which one would you prefer to use?

I think I'll go with UFW. Can you guide me through the steps?

Sure! First, install UFW if it's not already installed. You can do this with sudo apt install ufw. Let me know when you're ready for the next step.

Okay, I've installed UFW. What's next?

Next, you need to allow Nginx through the firewall. You can do this by running sudo ufw allow 'Nginx Full'. This will allow both HTTP and HTTPS traffic.

Got it! How can I check if the firewall is active?

You can check the status of UFW by running sudo ufw status. It will show you the current rules and whether the firewall is active.
