List of Tunneling/Firewall/Proxy/Censorship Bypassing ISP

As you can see, setting up such tunnels does not requires advanced skills, especially with the recent Linux distributions which come with pre-installed and pre-configured ssh servers.

With a little more skills, it is possible to tunnel just about everything into everything. For example, it is possible to tunnel PPP into HTTP, providing a full IP-stack tunnelling, including ICMP (ping...), DNS and servers (backward tunnels).

Opensource and commercial VPN solutions also come into mind.

See references for programs and papers about firewall bypassing below.

Security is not only a matter of firewall configuration, it must be seen at a larger scale. Do not rely on the firewall alone.

Censorship bypassing should not be only considered as a terrorist or hacker weapon, but also as tools for privacy, free speech, democraty and human rights protection (Please read papers written by PGP-author Philip Zimmerman, they are very instructive).
