bouncerbrick is a free source program, that you can use free in the terms of the GPL (General Purpose License).

bouncerbrick is a bouncer, that is, let you redirect tcpip conections to another host and port.

You can use it like any bouncer, but give you also the following features:

• Protect your system from masive connections trying a DOS (Denny Of Service).
• Making a log from all connections (connections, data and both).
• Tunneling, encrypt a connection between two points using two instances (the first encrypting, the second decrypting).
