Abstract: A method for sharing content using a Digital Living Network Alliance (DLNA) network is disclosed. The method includes the steps of creating a DLNA VPN (Virtual Private Network) between an inside-home DLNA network and at least one outside-home DLNA device, and delivering content from an inside-home DLNA device connected to the inside-home DLNA network to an outside-home DLNA device contained in the DLNA VPN in response to a request for content from the outside-home DLNA device. The method further allows continuous sharing of content, even if IP addresses of devices connected to the DLNA VPN are changed, by managing dynamic IP addresses of the devices connected to the DLNA VPN using an external network management server. Thus, the method allows outside-home DLNA devices to freely share content using a DLNA network. The method also allows various contents to be processed on a mobile terminal regardless of a storage space and processing capability of the mobile terminal.
