How do I set up a firewall for MongoDB?

To set up a firewall for MongoDB, you'll need to configure your server's firewall to allow traffic on the MongoDB port, which is typically 27017.

What specific rules should I add to the firewall?

You should allow incoming connections on port 27017 from trusted IP addresses only. For example, you can use a command like ufw allow from <trusted_ip> to any port 27017.

Is there a way to restrict access to certain IPs?

Yes, you can specify multiple rules for different IP addresses or ranges. Just repeat the allow command for each trusted IP.

What if I want to block all other IPs?

You can set a default deny rule after allowing specific IPs. For example, ufw default deny incoming will block all other traffic.
