基于NAT的中小型企业网络规划与设计

NAT Based Network Planning and Design for SMEs

NAT是将私网地址转换成公网地址的技术,主要用于实现私有网络访问公共网络的功能.这种通过用较少的公网IP地址代替较多的私网IP地址的方式,将有助于减缓因IPv4地址不足造成的地址匮乏.文章论述了NAT技术的工作原理,把NAT技术应用于中小型企业网中进行网络的规划与设计,以实现整个网络的通信.

NAT ( Network Address Translation ) translates private addresses to public addresses and is mainly used for private network accessing to public network.This method uses less public addresses to map more private addresses so helps slow down the depletion of network address due to the lack of IPV4address.This paper describes the principles of NAT and applies NAT into SMEs network planning and design to realize whole network communication.
