Tunna is a set of tools which will wrap and tunnel any TCP communication over HTTP. It can be used to bypass network restrictions in fully firewalled environments.


Metasploit's portfwd does the same thing but for that to work you need to have a meterpreter session and I have run into environments where It wasn't available for me. This has helped on various ocassions. Thought I'd share this with ya.

You do need a webshell on the server though in order for this to work.
