我是 Ipv6 的新手，正在尝试学习它。因此，我决定在我的 OpenWRT 路由器中使用 Hurricane Electric 的 6to4 隧道，因为我的 ISP 不提供 IPv6。它在我的路由器上完美运行。但是当我ping ipv6.google.com在 Windows 8.1 中尝试它时，它失败了，路由器中Destination host unreachable.的输出如下：tcpdump
13:52:39.648512 IP6 2001:470:XX:XXX:XXXX:XXXX:XXXX:XXXX > ff02::1:ff21:c98e: ICMP6, neighbor solicitation, who has fe80::109c:e1ff:fe21:c98e, length 32

该地址是我的 Windows 8，如NIC 状态中2001:470:XX:XXX:XXXX:XXXX:XXXX:XXXX所示。并且是我的路由器链接本地地址。Temporary IPv6 Addressfe80::109c:e1ff:fe21:c98e
我的路由器可以使用链接本地地址 ping Windows 8。但 Windows 8 无法使用链接本地地址 ping 路由器。
