Firewall Tunnel 1.0 Supports Linux, Windows and Solaris now

The Firewall Tunnel 1.0 release adds Windows
support and various bugs have been fixed to
improve it's stability.

Right now both the tunnel front-end and back-end can
run on Linux, Windows and Solaris. You can mix
front-end and back-end running on different platforms
as well which adds more flexibility in configuration.

The only limitation of functionality of Windows/Solaris
Backend is that it doesn't support "proprietary socket"
mode. Also the windows build depends on Cygwin and
the pre-compiled Windows binaries from the "Files"
section need Cygwin DLL to run.

Firewall Tunnel FE 0.7 &amp; BE 0.8 released!

Firewall Tunnel is a simple two-parts (FE:Frontend and BE:Backend) tunnel that allows servers behind a firewall to export services to clients outside the firewall.

Multiple TCP/UDP flows can be tunneled within one TCP connection. The true client address (IP address and port number) instead of the Tunnel FE/BE's address can be seen by the server which makes the server-side accounting or access control based on client address possible through Firewall Tunnel. ... read more
