The Barracuda MxTunnel is a tunnel and proxy server that allows you to circumvent firewalls/proxies, access resources that may be blocked, and to securely access internal resources on a business/home network. The Barracuda MxTunnel is a free and complementary BarracudaDrive product. The MxTunnel maintains a HTTPS (encrypted) connection between the MxTunnel and a BarracudaDrive server. The MxTunnel is installed on a client (local) computer such as a laptop or a work computer. The MxTunnel is then configured to connect to one or several BarracudaDrive servers, either directly or via a chained corporate proxy. The data tunneled between the MxTunnel and the BarracudaDrive server is encrypted with military grade encryption that cannot be broken.
