From Initex Software:
There are many network applications that do not support working through proxy servers and thus cannot be used behind a LAN or firewall(s). Proxifier solves this problem and gives you the opportunity to work with your favorite software without any restrictions. With Proxifier you can work with any Internet client (browsers, P2P, messengers, SSH, video/audio, games) through a network that is separated from the Internet by a firewall/proxy. Proxifier will provide you with added privacy in all your Internet activities. An example is sending and receiving email through a proxy server or by chaining multiple proxy servers together.
What's new in this version:
- Full Snow Leopard support.
- Experimental support for 64-bit kernel mode.
