The Tube allows you to auto-configure Microsoft Outlook, Outlook Express, Mozilla Thunderbird, Internet Explorer, Mozilla, Opera, Firefox to ssh tunnels of your choice for browsing, smtp, pop3,imap and more. This is a full unrestricted working tool for all your SSH Tunneling needs. Can be used for any SSH capable host where you wish to tunnel through.
So far i was using the more known ssh clients which took too much time to setup quickly when working in remote places. The Tube has a nice interface which can automatically configure my browser to use a ssh tunnel to reach a proxy. Or use it as a kind of netcat for ssh to create custom ssh tunnels to guide specific traffic for special applications.
I did not see yet a disadvantage as it does what it says. Once i contacted trilightzone support to check an issue which turned out to be a matter of adjusting the firewall rules.
