再代理服务器设反向路由和作NAT有什么区别？这两个我搞不太清楚
NAT 是地址转换. 可以解决公有IP不足和共享上网
反向路由 : 路由就是将数据转发出去, 反向是什么意思？偶没听说过 ,学习
反向路由, I think you are refering to port mapping(or port forwarding).
eg, your NAT server public ip: 203.126.85.21
your NAT server private ip: 10.0.0.1
your webserver: 10.0.0.20
if you want users on the internet to access your webserver, then you will need to map port 80 on the NAT so that requests for 203.126.82.21 on port 80 is forwarded to ip 10.0.0.20.
反向路由 ＝ 端口映射 ？
楼上解释的是NAT 的实现
