# Establish a connection to your EC2 instance

* In order for you to establish an SSH connection to your EC2 instance:<br>
  * **On the Security Group, add an Inbound Rule to allow SSH traffic** to your EC2 instance.<br>
  * **On the NACL, add both an Inbound and Outbound Rule to allow SSH traffic** to your EC2 instance.<br>
* **NACLs = Stateless (Less traffic is allowed**; i.e. return traffic must be explicitly allowed).<br>
* **Security Groups = Stateful (Full traffic is allowed**; i.e. inbound AND outbound).
