RouterOS7.9.2 IPV6设置求助

㊣川仔.Net

搞了2、3天，看了各种文章还是没有搞定

光猫是桥接模式
ROS中的Interface有3个：LAN、WAN、pppoe-out
IPV6的 DHCP client已经能获取到prefix了
电脑获取不到IPV6的地址，也访问不了IPV6的网站
没有开防火墙

OP不好吗

用了ros的防火墙，来控制小孩上网，也还挺稳定的，似乎没有出过问题。

他们说升级到7.10就好了。

我家里的躺着吃灰了。太难了。

看前缀，楼主是移动的宽带？

如果彻底没有设置防火墙的话也许就是问题。

这几条必不可少，跟v4不一样，IPv6的正确运行特别依赖于ICMPv6，必须要保证能转发。

/ipv6 firewall filter
add action=accept chain=input comment=\
    "defconf: accept DHCPv6-Client prefix delegation." dst-port=546 \
    protocol=udp src-address=fe80::/10
add action=accept chain=input comment="defconf: accept ICMPv6" protocol=\
    icmpv6
add action=accept chain=forward comment="defconf: accept ICMPv6" protocol=\
    icmpv6

多找一些教程，有些文章误导人

falltree

ros获得了ipv6后，还要选择菜单ipv6，子菜单address，from pool里面选择之前获取ipv6时设置的ipv6 pool名字，然后interface选择lan
这样才能把ipv6地址通过lan接口分配给局域网的设备，各设备的ipv6地址就从这个pool里分配。

你的描述似乎少了这步，只做了ros获取ipv6，并没有做分配ipv6的设置

已基本搞定了，谢谢各位

最后做了些啥，贴图出来看看，也方便后来人参考。

我的就只设置了DHCP client就可以用了，没有其他特殊设置呀

IPv6 防火墙里别忘了设置这一条：

/ipv6 firewall mangle add action=change-mss chain=forward comment="Change MSS to PMTU, make HTTPS happy" new-mss=clamp-to-pmtu out-interface-list=WAN passthrough=yes protocol=tcp tcp-flags=syn

坚持↓去

麻烦给个搞定的教程，谢谢了
