BarracudaDrive is a secure application server with an integrated scripting language, database engine, WebDAV server, Web File Manager, tiny SSL server, HTTPS tunnel, and various SSL VPN clients for the HTTP tunnel. The server also comes with a content management system and a bulletin board system.
BarracudaDrive is designed for the non-technical user. The product includes ready to use components, which can be used without any configuration. The server can automatically configure home/business routers by using UPnP, if installed on a private network. The server includes a Dynamic DNS client that keeps the domain name working if one has a varying IP address -- i.e. a dynamic WAN IP address.
