Abstract:	隨著寬頻的普及，網路安全及相關應用益形重要，尤其在國內外頻繁互動及全球化趨勢的影響下，如何建立一個安全通道，讓遠端使用者透過完整的加密保護及防火牆等功能，安全地存取組織內部資料，便成為一個重要的課題。跨區、跨縣、跨國企業的發展，產業「地球村化」的時代已正式降臨，VPN漸成企業商業與協同應用的重要選擇。在這些企業中，資訊及資料的傳遞以及遠端控制、管理與遠端協助的需求與俱增。雙邊辦公室之間的聯繫、溝通與協調更是不可或缺。若可將以上事項透過網路的方式進行將可大大提升便利性同時也可以降低整個運作之成本。一般企業單層VPN架構通常允許直接連接內部區域網路，但對於雙邊DMZ的存取則無法進行或需要先進入對方內部網路再進入DMZ，如此架構對於雙邊的內部網路構成安全的威脅。因此單層VPN架構已不敷跨國企業之需求，需要雙重VPN加以實現。多重VPN是比較具有彈性的架構，當需要內部網路對內部網路、內部網路對DMZ、DMZ對DMZ等進行資料交換或資料同步，甚至進行遠端維護時，多重VPN皆可達成必要的需求。 Along with the broadband popularization, the network security and the related ap-plication is getting progressively importantly. How to establish a secret channel for re-mote user to transfer the secret information has become an important task. Globalization in industry epoch has already arrived. VPN has become a crucial op-tion for enterprise and coordination purpose. Information, data transmission, remote controlling, management are increasing in enterprises. Communication between office are inevitable among all. If those things can be dealt by network, it not only facilitates the work but also lowers the operation cost. Generally speaking, single layer VPN allows to connect to LAN within the intranet. However, DMZ's storage is unable to connect to LAN. It needs to access to other's in-tranet first before DMZ and this structure might be cause a security threat to two sides' intranet. Therefore, single layer VPN is no longer satisfied with multi-nations coporate's need. Multiple layer VPN is required. When you need to transfer data or information in “Lan to Lan”,”Lan to DMZ”,”DMZ to DMZ”, the multiple VPN is a more flexible structure.
