分享一个 OpenWrt IPv6 的配置
配置
修改 /etc/config/dhcp
config dhcp 'lan'
option interface 'lan'
option start '100'
option limit '150'
option leasetime '12h'
option ra_management '1'
option ra 'hybrid'
option dhcpv6 'hybrid'
option ndp 'hybrid'
config dhcp 'wan6'
option interface 'wan6'
option dhcpv6 'hybrid'
option ra 'hybrid'
option ndp 'hybrid'
option master '1' # 这里 wan6 配置 master
上面配置中的 lan 部分，可以通过 luci web 页面配置，配置如下：
修改配置完成后重启网络服务 /etc/init.d/network restart 即可在lan侧获得 IPv6 地址
如上配置IPv6 混合模式/也可以配成中继模式（relay）。
注：此时光猫没有做任何修改，还是NAT 路由模式，并没有要求改成桥接！
