Entunnel® is no longer in active development
VanDyke Software has made the decision to focus our development efforts on SecureCRT®, SecureFX®, and VShell®. The port forwarding (tunneling) functionality that Entunnel provides can be found in SecureCRT, which also provides shell access and terminal emulation.
Technical support for Entunnel ended on February 28, 2007. No new versions of Entunnel are scheduled to be released.
