其实还没有看懂你的原理，可否详细说明一下？

谈不上什么原理 用的libpcap的库 用main函数开两个线程 
申请两个回调函数（监听到802x包的时候就返回到函数） 
分别监听路由器的两个网卡 一个线程判断源MAC来自PC的话 
就原封不动的用WAN的网卡把这个包复制发送过去 
另一个线程依然 测试认证是没问题的 但是路由器的WAN网卡 
却无法上网  不知道其它版本的锐捷 能否使用

我加了一个改写MAC的功能，即当LAN上出现合适0x888e且源MAC为PC
_MAC的数据包时，把其源MAC改为路由WAN口的然后发送至WAN；而�
��WAN上出现目标MAC为路由MAC时，把目标MAC改为PC_MAC再发送至LAN
。这样应该能够实现路由不克隆MAC地址的情况下由电脑代理��
�认证，从而使得来自路由的MAC的数据包允许通过交换机。可�
��这样的话电脑显示认证成功，但得不到IP；路由上用udhcpc -i 
eth1也得不到IP……不知道问题出在哪了……

接上，如果直接使用原本的程序，在路由WAN口设置MAC地址克��
�为电脑的，也是一样无法获取IP的状况（电脑和路由都不行��
�……如果电脑接进线，在电脑上认证好以后看到了IP、掩码��
�网关，然后开启代理，进线插到WAN，电脑插LAN，再认证，等�
��证成功后立即手动设定WAN口IP和掩码为之前记录的，这样也�
��能连通网络，ping网关是不通的……

进一步测试除了替换MAC以外还代理DHCP数据包（从LAN代理到WAN�
��改变里面的两处MAC地址）仍然无DHCP 
Offer……实在想不出来哪里还有问题……

5楼的同学，看你们学校是先锐捷认证后DHCP的话 
这个方法貌似不管用，我们学校是直接DHCP获取IP的 
然后认证就能上网 我代理了协议之后 
认证没有任何问题，但是无法上网

感觉DHCP服务无响应跟不能上网有可能都是交换机仍然没有允�
��数据包通过的表现，实际还是一个问题……
