Tunnelling to Network Devices

Tunnelling opens a temporary connection to a device on the TetherBox's local network. Use it to configure a camera, recorder, switch or other authorised device remotely, without port forwarding or a static public IP.

 Before You Open a Tunnel

The TetherBox and target device must be online, and TetherX must have discovered the device. The target also needs an enabled web interface or other service on the port you want to reach.

The Tunnels tab is available to administrators, integrators and TetherX staff. Your account needs Allow Remotely Tunnelling to Devices in its permissions. Integrators and staff also need Support Access enabled for the timeline.

 Open a Known Web Interface

Where TetherX has found a device web interface, use the tunnel button beside its IP address in the device page or list. TetherX opens the tunnel and the device page together, preferring HTTPS over HTTP.

Use the Tunnels tab instead when you need another port or want to record why you opened the connection.

 Choose a Port and Open a Tunnel

  1. Open AdminDevices, or Cameras for a camera.
  2. Open the device, then its Tunnels tab.
  3. Choose a discovered port, or choose Custom... and enter the port number.
  4. Add a reason. It appears in the tunnel list and the Audit Log.
  5. Click Open Tunnel.

Opening a tunnel from the Tunnels tab

The port menu lists services TetherX found on the device, with HTTPS and HTTP first. It can also list RTSP, SSH and VNC. Some devices need more than one port, so open a separate tunnel for each service you need.

 Use and Close the Tunnel

The list shows the address to open, target port, reason and remaining time.

The list of open tunnels

Tunnels close automatically after one hour. Use the red close button to end one sooner. On an HTTPS device, the browser may warn about its self-signed certificate. Confirm the certificate is for the device you intended to reach, then use the browser's Advanced option to continue.

Tip: Close a tunnel as soon as you have finished configuring the device, rather than leaving it open for the full hour.

 Use Tunnels Safely

Target protocol Connection protection
HTTPS or SSH Encrypted end to end
HTTP or Telnet Unencrypted, use only on a trusted network

Tunnelling does not require port forwarding or a static IP on the site network. It grants access to the device's own interface, so make configuration changes only when you are authorised to do so.

Older devices that require ActiveX, Java, Silverlight or another browser plugin may not work in a modern browser. Check for a manufacturer firmware update or use the device's supported management method.

Warning: HTTP and Telnet do not encrypt traffic. Use them only on a trusted network.
