Tunneling, or port forwarding, is a way to forward otherwise insecure TCP traffic through SSH Secure Shell for Workstations. You can secure for example POP3, SMTP, Telnet, FTP, VNC and HTTP connections that would otherwise be insecure.

You can control not only SSH server but all computers in your intranet network. ZaTunnel is a SSH tunnel and port forwarding program for devices supporting Microsoft Compact Framework 2.0. ZaTunnel boasts a handful of improvements that make remote administration of Unix and other servers via Telnet/FTP/VNC protocol using mobile devices safely and more efficient.
