Tunneling with Secure Shell

Remote access to network resources is increasingly a business requirement, but external network threats must be neutralized. A Secure Shell (SSH) capability called port forwarding allows nonsecure TCP/IP data to be tunneled across public and private networks through a secure, encrypted connection. The benefits of port forwarding are illustrated by a series of concrete examples. VanDyke Software's Windows clients and servers provide an end-to-end tunneling solution to secure client/server applications, which may serve as a lightweight alternative to a Virtual Private Network (VPN).
