74 74  
75 75  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.

77 77  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.
78 78  1. Give a free port to the user and ask them to configure RSSH page in the gateway.
