HOWTO Documents > Tunneling (port forwarding) with SSH Secure Shell Client (Windows)

Important Notes: a secure SSH tunnel only works while you maintain a connection to CCIS using SSH. If you disconnect from us or quit the SSH program, your tunnel is no longer operative. Although this document focuses on the use of the SSH Secure Shell Client there are other SSH clients for Windows that will also allow tunneling.
