Adapted from the home page:

A *nix tool for creating encrypted Network links. VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption. Open-Source and distributed under the GPL, it supports IP, PPP, SLIP, Ethernet and other tunnel types. VTun is easily and highly configurable, it can be used for various network tasks.

VTun can also work over SSH -- it is fairly flexible.

Uses the Blowfish cipher for fast and efficient encryption and MD5 hashing keys, both at 128 bit strength.

Its use of ciphers in ECB mode and other shortcomings means that you should only in last resort, if you cannot deploy IPsec or OpenVPN.
