I like using dns2tcp, it's a lot easier to set up as it works on the transport layer (TCP), not the network layer (IP), and it seems a bit more reliable in my experience. http://blog.rootshell.be/2007/03/22/dns2tcp-how-to-bypass-firewalls-or-captive-portals/ http://blog.rootshell.be/2007/03/22/dns2tcp-how-to-bypass-fi... http://www.hsc.fr/ressources/outils/dns2tcp/download/README http://www.hsc.fr/ressources/outils/dns2tcp/download/README http://www.hsc.fr/ressources/outils/dns2tcp/download/ http://www.hsc.fr/ressources/outils/dns2tcp/download/

Second dns2tcp, although there's also Heyoka http://heyoka.sourceforge.net/ http://heyoka.sourceforge.net/, Netcross http://www.primianotucci.com/os/netcross-ip-over-dns-tunneling http://www.primianotucci.com/os/netcross-ip-over-dns-tunneli..., and a rather interesting presentation from Defcon a few years back that showed a more detailed and realistic scenario of using DNS tunneling to punch through a firewall and retrieve database records. I can't locate it right now, but I'll take a look if anyone's interested.

    Haha, fifteen minutes of Googling later, here you go: Slides: https://www.defcon.org/images/defcon-16/dc16-presentations/defcon-16-ricks.pdf https://www.defcon.org/images/defcon-16/dc16-presentations/d... Talk: https://www.youtube.com/watch?v=IkXG14MA3M4 https://www.youtube.com/watch?v=IkXG14MA3M4 I kept missing the search term. It was "data exfiltration" not "dns tunneling."
