MyEnTunnel is a simple system tray application (or NT service) that establishes and maintains TCP SSH tunnels. It does this by launching Plink (PuTTY Link) in the background and then monitors the process. If the Plink process dies (e.g. connection drops, server restarts or otherwise becomes unreachable) MyEnTunnel will automatically restart Plink to reestablish the tunnels in the background. It tries to use as little CPU and system resources as possible when monitoring (When the "Slow Polling" option is enabled it only does one context switch per second).

Edit
It is a great little app that will connect you to your favorite SSH server. While it does do port tunneling to a limited extent, it does lack features like choosing a specific cipher algorithm.
