Connect through Host (cascade connection)

This feature allows you to use one of your Hosts as an intermediary for accessing other Hosts. Another term is cascade connection.

A typical use of this feature is when you need access from the outside to multiple PCs in your local network. Instead of exposing each PC to the outside world you can only allow access to a single Host PC and make it an intermediary for connecting to other Hosts in the LAN.

Important!

Currently this feature only works for direct connection. I.e. you must use the IP address or DNS name of each remote Host in the cascade. The Internet-ID is not supported for cascade connections yet.

Configuring the intermediary Host

  1. Install the Host on the computer which will act as an intermediary and make sure that the Host is directly accessible to the Viewer.
  2. In the Viewer, click Add connection and enter a descriptive name and IP address (or hostname) of the Host: Adding intermediary Host connection
  3. Uncheck Connect now and click OK. A new connection will be created in your address book: Connection for the intermediary Host created

Configuring the target Host

Important!

For the cascade connection to work the target Host PC must be directly accessible from the intermediary Host PC. Typically, this means that both computers are in a LAN and the intermediary Host is used as a "point of entry" for accessing the other LAN computers from outside the network.

  1. In the Viewer, click Add connection and enter a descriptive name and IP address of the target Host. In most cases the IP address that you enter here should be from the same subnet as the IP address of the intermediary Host: Adding target Host connection
  2. Uncheck Connect now and click OK. A new connection will be created in your address book: Connection for the target Host created
  3. Right-click the target Host connection and select Properties. Connection menu - Properties
  4. Open the Network tab, check Connect through the host and in the drop down menu select the intermediary Host: Connection properties - Network
  5. Click OK and close the Properties window.

Connecting to the target Host

  1. Right-click on the intermediary Host connection and select Logon: Intermediary Host logon
  2. Enter the access password for the intermediary Host and click OK: Enter password
  3. You are now logged in to the intermediary Host: Logged in to Intermediary Host

    Important!

    When logged in on a Host you are being connected to it but not actively using any connection modes, so you will not interfere with the remote user's work who is sitting at the remote PC. Learn more about logging on/off and connection modes.

  4. Now right-click on the target Host connection and select Logon: Target Host logon
  5. Enter the access password for the target Host and click OK: Enter password
  6. You are now connected to the target Host. Logged in to Target Host You can now start a connection mode (e.g. Full Control) by selecting the desired mode on the Viewer toolbar and double-clicking the target connection.

Important!

You must stay logged on to the intermediary Host during a remote session with the target Host.
