Set up a tunnel with PuTTY

Launch the PuTTY application.
For Host name, enter the TeamForge Lab Management Manager host "$external_host".
For Connection type, enter "SSH".
In the left pane, open Connection list.
Open SSH list and click Tunnels.
In the right pane, enter "3390" for Source port and "cu087.$vars.mgr_domain:3389" for Destination, and click Add.
Select the forwarded port from the list and click Open.
At the login prompt, enter your Lab Management username and password.

The RDP tunnel is now set up.

Note: This procedure is equivalent to running this SSH command:

ssh -L3390:cu087.$vars.mgr_domain:3389 $external_host
