竟然是这个原因……
看来还是用脚本吧，默认网关几年前就改成 2402:f000 的那个了，只是之前旧的最近才停好像。
2402:f000/32 是清华的 IPv6 段，2001:250::/32 是 cernet2 的。
http://bgp.he.net/net/2402:f000::/32
http://bgp.he.net/net/2001:da8::/32
它们中间还隔了个 "CERNET2 at Tsinghua University"

终于解决了。问题是isatapd现在无法用了。。。我搜到了blaok的脚本
<https://gist.github.com/Blaok/3110f1b596aa732a94b8>
，他脚本配置使用2402:f000:1:1501:200:5efe:a66f:1501作为默认网关，用他的脚本就没问题。为什么突然用isatapd不行我不知道。。
你们用isatapd吗？

我也认为是路由器问题，但是我用无线理论上被人跟我用的一样的路由器吧。我还是觉得是我机器自己的问题。关掉ufw也没用。

不了解贵校网络情况，但mtr看起来像是网关有问题，比如没有默认路由

你试试 mtr --tcp -P 80 2402:xxx:xxx 这个命令，分别从两边测试一下对方。

Tuna大神们，
我最近用IPV6无法上网之前Ok，我知道搞网络最讨厌这样的用户，别担心这邮件包括tcpdump和细节，我也自己调试了不少，求帮助。情况如下：
最喜欢贴调试信息的了……讨厌的是跪求神马的。
所有 v6 网站都上不去，还是只是这个日本服务器？
双栈拿到的 v6 IP 地址？
