[疑问] 求助大佬们帮忙看下这一段KS的ipv6设置哪里出错了？

后台显示的地址是：2001:41d0:2:922c::1

interface配置加上了：

auto vmbr1
iface vmbr1 inet static
        address 10.1.1.1/24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

iface vmbr1 inet6 static
        address 2001:41d0:2:922c::1/64
        post-up iptables -t nat -A POSTROUTING -s ‘10.1.1.1/24’ -o vmbr0 -j MASQUERADE
        pre-down iptables -t nat -D POSTROUTING -s ‘10.1.1.1/24’ -o vmbr0 -j MASQUERADE

        post-up /sbin/ip -f inet6 route add 2001:41d0:2:92ff:ff:ff:ff:ff dev vmbr0
        pre-down /sbin/ip -f inet6 route del 2001:41d0:2:92ff:ff:ff:ff:ff dev vmbr0
        post-up /sbin/ip -f inet6 route add default via 2001:41d0:2:92ff:ff:ff:ff:ff
        pre-down /sbin/ip -f inet6 route del default via 2001:41d0:2:92ff:ff:ff:ff:ff
        post-up /sbin/ip -f inet6 neigh add proxy 2001:41d0:2:922c::1 dev vmbr1
        pre-down /sbin/ip -f inet6 neigh del proxy 2001:41d0:2:922c::1 dev vmbr1

开的小鸡可以分配到ipv4，v4外网是通的。
但是母鸡v6不通外网，小鸡也v6没有外网。

ip addr

vmbr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
    link/ether 62:90:4f:70:77:4f brd ff:ff:ff:ff:ff:ff
    inet 10.1.1.1/24 brd 10.1.1.255 scope global vmbr1
       valid_lft forever preferred_lft forever
    inet6 2001:41d0:2:922c::1/64 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::6090:4fff:fe70:774f/64 scope link
       valid_lft forever preferred_lft forever

求大佬支支招orz 照抄以前ks3c的配置也不对。网关已经按照规则第四节第二位后全ff了应该是没错的。

母鸡小鸡之间互相ping v6正常，但是ping外网v6全部丢包  外网用v6也联不通服务器。

感谢大佬 我决定发个工单问问是不是网关不对！
