求助 ubuntu10.10双网卡+路由器共享上网（结贴,已搞定）

ubuntu10.10无线+有线
无线链接AP可以上网
添加有线 IPV4 方法设置为 与其他计算机共享，并且启用所有用户可用，链接路由器的WAN口
启用有线网络，一直提示连接已建立，连接已断开。

ipconfig 如下（这个状态很奇怪，显示连接已建立的时候，才能看到共享链接分配的IP，并且链接状态是不停的提示已建立，已断开）
eth0 Link encap:以太网 硬件地址 00:24:7e:68:88:dd
inet 地址:10.42.43.1 广播:10.42.43.255 掩码:255.255.255.0
inet6 地址: fe80::224:7eff:fe68:88dd/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 跃点数:1
接收数据包:404 错误:0 丢弃:0 过载:0 帧数:0
发送数据包:164 错误:0 丢弃:0 过载:0 载波:0
碰撞:0 发送队列长度:1000
接收字节:185783 (185.7 KB) 发送字节:37516 (37.5 KB)
中断:20 Memory:fc100000-fc120000

route -v （这个状态跟上面的类似，也是显示已建立的时候，才会显示10.42.43.0的路由表，显示已断开的时候，就不显示）
内核 IP 路由表
目标 网关 子网掩码 标志 跃点 引用 使用 接口
10.42.43.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 2 0 0 wlan1
link-local * 255.255.0.0 U 1000 0 0 eth0
default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan1

以上的状态，注定杯具的是另外链接路由器的机器，在WAN口，一直无法获得IP （路由器的WAN口的设置是没有问题的，因为用XP当主机来共享整个环境就完全没有问题！）

附上我上面描述的那个链接一会提示 链接已建立，一会提示连接已断开的图。。。 让人很抓狂

====================================================================================================
狂搜相关的文章之后，于是通过自己添加/etc/network/interfaces 修改net.ipv4.ip_forward=1 等等 。问题依旧 有线网卡，始终提示连接已建立，链接已断开
路由器的WAN口也一直获取不到IP


希望看到这篇帖子的朋友，帮忙给分析下，分享下思路
谢谢先了……

熬夜升级到了11.04问题依旧
Wireshark抓包看了下，跟WAN口有通信
遂翻了下日志
