基于Packet Tracer的NAPT教学设计及实现

Design and Implementation of NAPT Teaching Based on Packet Tracer

为了克服私有网同时与公共网通信的主机数量就受到NAT的公共IP地址数量的限制,NAT被进一步扩展到在进行IP地址转换的同时进行Port的转换,这就是NAPT(Network Address Port Translation,网络地址端口转换)技术。本文重点阐述基于Packet Tracer的NAPT教学设计及实现过程。

When private network communicates with public network, the＇number of hosts will be constrained by the number of public IP address of the NAT. In order to overcome this problem, NAT has been further extended to conduct port translation at the same time of IP address translation. This is the NAPT（Network Address Port Translation） technology. This paper mainly elaborated the teaching design and implementation process of NAPT technology based on Packet Tracer.
