1、Internet 有两种IP address,第一种是Public IP address,第二种是Public reserved IP address(在互联网是没有routing的,是自己处理)。
2、ChangeIP的DNS不接纳local private address。
3、确认第一楼的信息是可以update ether1(WAN) IP address (如果IP address是public IP address or public reserved IP address)
今天才明白怎么会事,就是以前中国移动给你光猫,后面modem你自己处理。那个时候同样的changeip DDNS script都可以工作,是否有中国移动给你Reserved IP address,所以那个时候changeip ddns让你update他们的server。
现在呢?移动给你一个盒子,但是拨号过去只得local private address,那么我是changeip ddns script to update WAN address,由于是local private address,ChangeIP不给你update他们的server。所以的Changeip是无法做到的。除非他们修改他们的update限制,就是允许local private IP address。
