在物聯網環境中，許多的智慧物件將自動形成一網路，其中，低耗能的Zigbee通訊協定已漸漸被廣泛的使用在各式的智慧物件中，如生醫設備、感測裝置、電力計等，具Zigbee傳輸功能的物聯網AP在這樣的環境中將可收集這些智慧物件的資訊。行動裝置在現今的生活中已成為不可或缺的載具，透過UPnP的通訊協定，物聯網AP所收集的資訊將可顯示於智慧型手機。然而，手機與AP間透過UPnP的連線來獲取資訊，在現今的技術中僅能在區域網路中實現，這主要的瓶頸是來自於UPnP的服務無法達到跨網能力。
有鑑於此，本論文將於物聯網AP中，設計及實作一『遠端存取家用網路系統』，此系統主要結合PPTP通道技術及UPnP通訊協定，使物聯網AP所收集而得的智慧物件資訊可透過此系統分享至遠端網路的設備，而遠端設備(如手機)亦可經由物聯網AP來控制其所連結的智慧物件。本論文除了實作『遠端存取家用網路系統』外，亦在iOS行動裝置上，設計一套具UPnP服務之應用軟體，用來驗證本系統的功能可提供於跨網UPnP之服務。

Recently, the advance and development of internet has changed people’s lifestyle. Although the internet has brought many of the convenience, however, it is crucial for people to take the initiative to input their own information. As we can see, the interaction between people and objects become more frequently, so that we also expect that the object itself can be smarter which can automatically provide the services and messages that people are concerned about. 
UPnP (Universal Plug and Play) is a standard proposed by Microsoft. It provides automatic detection, discovery services, zero-set configuration, and other important functions. It implements the concept of machine to machine communication as Internet of Things (IoT), which can be the most representative smart home. However, the UPnP can only implement within the LAN restrictions. Thus, different UPnP in the same network cannot communicate each other, resulting in the superiority of UPnP cannot be unleashed.
In this thesis, we will develop the IoT AP to design the system architecture of the combination between VPN and UPnP to solve the problem which the UPnP network cannot communicate each other in different home network. Therefore, we use iOS mobile device to develop an UPnP service application software to verify the feasibility of this thesis.
