Hi, I have an droplet which is running a NGINX and I wish to block my another droplet running Mongo to be visible exclusively for the NGINX one. Could you help me? Both are running Ubuntu.

Using ufw, first you need to deny all traffic to your database port

sudo ufw deny 3306/tcp

then allow your IP to your server:

sudo ufw allow from Your.IP.Address to any port 3306 proto tcp
