In addition to explicit tunnels, you can use a Teredo tunnel. [0] Miredo is the Teredo implementation that everyone uses on Linux. The advantage is that Teredo automagically configures itself. Some of the disadvantages are that it can be really slow or otherwise unreliable, and kinda slow to configure.
