I've created a Surebackup job that runs an Oracle Linux VM in a Virtual Lab. The Virtual Lab is configured with a static mapping to allow access from outside the lab into the isolated network. I confirmed this by browsing the the static mapping IP and get the launch page for Apache (also running on the server). When connecting via Putty/SSH to the same IP I get a login prompt, enter the username but am never prompted for a password. Eventually the sessions times out.
