目前树莓派和 Windows 电脑都是有线直连光猫,但是树莓派却无法使用 IPv6 访问互联网,很奇怪。 开始以为光猫有问题,但尝试过用 WIFI 连接路由器,同样是手机正常用 IPv6 ,但是树莓派不行。 在此请教各位大佬,看看有没有解决办法。
Windows 电脑能正常获取到 IPv6 ,也能正常访问:

有获取到公网 IPv6 ,局域网内能通,就是访问不了外网。

派的 v6 防火墙主要看 mangle 表和 nat 表

jwj OP 重新安装了个 OpenWrt 系统,也是 IPv6 无法上网,但是 IPv4 能。
之前的 Debian 没有安装 iptables 、ufw 和 firewalld ,大概可以理解为防火墙并没有启用? 然后 OpenWrt 的防火墙出站也是默认放通的,那大概率能排除防火墙问题? |
