+Connect the sandbox to a network overlay/VPN tunnel created by firetunnel utility. This options
+tries first the client side of the tunnel. If this fails, it tries the server side. If multiple tunnels are active,
+please specify the tunnel device using \-\-tunnel=devname.

+The available tunnel devices are listed in /etc/firetunnel directory, one file for each device.
+The files are regular firejail profile files containing the network configuration,
+and are created and managed by firetunnel utility.
+By default ftc is the client-side device and fts is the server-side device. For more information
+please see man 1 firetunnel.
