摘　　要：网络地址翻译(NAT)设备的应用很好地解决了IPv4地址不足的问题,但同时也给端到端的连接带来了障碍。目前,对于UDP通信穿越NAT已经有了一些通用的、有效的解决方法,但对于TCP端到端通信,NAT穿越技术还需继续研究。本文给出了一种较为简单有效的TCP穿越NAT的方法。该方法可以完成市场上主流NAT设备的TCP穿越。The use of NAT equipment has given a perfect solution to the problem of IPv4 address scarcity, but peer to peer communication obstacles will follow. At present, for the UDP through the NAT has some universal and effective solutions. On the contrary, for TCP communication, NAT traversal technology are researching till now. This paper presents a simple and efficient way to solve problem of TCP through NAT. The mainstream NAT equipment could be passed by using this method.
