Ping Tunnel
Ping Tunnel is a tool for reliably tunneling TCP connections over ICMP echo request and reply packets (commonly known as ping requests and replies). It is useful for evading firewalls that, for whatever reason, prevent outgoing TCP connections, but allow in- and outgoing ICMP packets. The tunnel works by having a proxy run on a machine ping-able from the inside of the firewall, with the client running on the local machine from which TCP access is required.

- 13 Jan 2009 22:38
Changes: This release adds support for syslog and compilation on Windows. It also enables tunneling over UDP port 53, and fixes a few minor bugs (in particular, ptunnel should no longer crash due to failed DNS lookups).
- 26 May 2005 09:03
Changes: This version fixes a potential crashing bug when using authentication, which could affect both proxy and client. Ping Tunnel now opens the log file in append-mode instead of truncating it if it already exists.

works great on Solaris & OpenSolaris/Nevada. Keep up the good work.
Works very well
Downloaded version 0.61 on my Mac OS X 10.3.9, and into
my Fedora Core 3 server. Compiled clean on both
environments.
Run it and it worked first time.
Excelent!
