67 67  1. Prepare a Linux server with public IP. The gateways need to be able to create SSH connection to this server.

69 69  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.
70 70  1. Give a free port to the user and ask them to configure RSSH page in the gateway.
