64 64  
65 65  1. Prepare a Linux server with public IP. The gateways need to be able to create SSH connection to this server. We recommend to use a server that performs no other function than to support the RSSH access, and to have no additional accounts active, and no access from the Internet that uses ID/password authentication.
66 -1. In the gateway settings, The Login ID will be the SSH user for this server and the Host Address is the server address.

67 67  1. Ask your end user to send you the key generate in the gateway and put them in /home/<Login ID>/.ssh/authorized_key file.
68 68  1. Give a free port to the user and ask them to configure RSSH page in the gateway.
69 69  1. In your server or other machine, you will able to access to the end user device by below command:
