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!
