我在这里没有任何想法：我在 Ubuntu oneiric 上运行移动 IPv6，并采用简单的固定地址设置。
mip6d 建立了隧道，但隧道一建立我就输了全部网络连接。我无法 ping，无法 telnet/ssh，现有连接中断，甚至 ping6 ::1 也显示“操作不允许”。我还有其他网络接口，这些接口也断网了。
没有防火墙，没有拒绝或删除任何内容的 ip6tables 规则，ufw 被禁用，并且我以 root 身份运行。
如果我错误配置了 MIPv6 以致无法建立隧道，这种情况就不会发生，我可以 ping 通一切。
家乡代理为 2001:db8:aaaa::4 移动节点为 2001:db8:aaaa::2
一旦我关闭 mip6d，我就可以再次 ping 通外部设备和 ::1，但我无论如何也想不明白为什么我会失去连接一切当隧道启动时，即使在其他网络接口上。
这个问题现在对我来说确实是一个大问题，我感谢任何有用的指点或提示。
mip6d 是 v2.0.2-umip-0.4
这是我的家庭代理配置：
#mip6d.conf : A basic Home Agent example
NodeConfig HA;
DebugLevel 10;
DoRouteOptimizationCN disabled;
Interface "eth1";
UseMnHaIPsec disabled;
IPsecPolicySet {
HomeAgentAddress 2001:db8:aaaa::4;
HomeAddress 2001:db8:aaaa::2/64;
IPsecPolicy HomeRegBinding UseESP;
IPsecPolicy TunnelMh UseESP;
}
这是我的移动节点：
# mip6d.conf : A basic Mobile Node example
NodeConfig MN;
DebugLevel 10;
DoRouteOptimizationCN enabled;
Interface "eth1";
UseMnHaIPsec disabled;
DoRouteOptimizationMN enabled;
UseCnBuAck enabled;
MnHomeLink "eth1" {
HomeAgentAddress 2001:db8:aaaa::4;
HomeAddress 2001:db8:aaaa::2/64;
}
这是移动节点上mip6d的日志输出：

答案1
回答我自己的问题：
我能够“修复”这个问题。事实证明，只要连接成功，一切都会正常。我在 HA 和 MN 之间的路径上有一个路由器，该路由器配置不正确，虽然在 MN 上创建了隧道，但绑定更新从未到达 HA。
现在，我无法在 slackware 上重现实际错误。然而，在 Ubuntu 上，网络堆栈几乎完全崩溃，直到隧道建立并且 MIPV6 运行。
在 MN 移动期间，会出现同样的问题 - 您无法 ping 或建立任何网络连接 - 但一旦移动完成，一切都会恢复正常。
真的很奇怪。我倾向于相信这是 Ubuntu 11.10 的问题
