12. On the Tunnels panel, choose a local port not in use for each host:port tunnel that you want to establish:
     
    • Source port field—The localhost port to which you connect
    • Destination field—The ePO server or Agent Handler Host IP address you connect to in hostname:port format.
      
      NOTE: You can obtain the ePO Application Server instance and Agent Handler instance IP address from the respective stack Outputs or EC2 instance details.
       
    • Click Add for each host that you want to be part of in your saved configuration.

NOTE: You can add multiple remote hosts like Agent Handler to establish the tunnel connection; then, save the session configuration.

       IMPORTANT: Leave the window open. You can minimize it to get it out of the way. But, don't close the window until you're ready to end your session.
        
    5. To verify if the tunnel has been established, view the Putty Event Log.
