Nope, but there are a few free Solutions for Linux or *BSD. You can use for
example PPP over an SSH tunnel, or you can use CIPE, it is a UDP based
encapsulation and should work with masquerading, too.

The problem with TCP-over-TCP is, that this works pretty bad because of
wrong bandwith prediction of the framed TCP because there are too much
buffers involved. Packet based VPNs like GRE, IPIP or UDP is better here.

http://www.freefire.org/ contains some of those free VPN Tools. In addition
to that Linux offers the possibility to masquerade GRE Connections, the base
for MS VPN Services.
