# first you must stablish iptables rule for keeping port 22 closed
This is a technique called "knocking" (knock knock) to open ssh port only when we need it in a secure way, just as if it was a "safe box" (using a combination of access to specific ports and specific order).
It's very secure because only opens access to the ip address which get connected and give correct combination order.
