拓扑结构,中国移动家庭智能网关GS3101 + OpenWrt GCC 5.3.0 12009
GS3101 为一级主路由,是光猫直接拨号,通过GS3101到一个lan口接到openwrt的wan口。其中分配给gs3101网关的ipv6前缀是60位,二级路由获取到该前缀后,给二级路由下属设备分配的前缀是64位
成功的配置需要确保你的二级路由器获得的ipv6的前缀是64而不是128。
gs3101网关设置如下:
默认登录用户名CMCCAdmin,密码aDm8H%MdA
如果自动分配不成功,则自己分配,注意前缀必须和家庭网关状态里面的前缀相同,前缀长度大于60即可:
我openwrt用ssh连上后用vim设置如下:
开头注释那行为路径

另外还设置了ip6tables
ip6tables -F
ip6tables -X
ip6tables -P INPUT ACCEPT
ip6tables -P OUTPUT ACCEPT
ip6tables -P FORWARD ACCEPT
设置完需要重启网络,防火墙,odhcpd
/etc/init.d/network reload
/etc/init.d/firewall reload
/etc/init.d/odhcpd restart
设置完毕,可能你在二级设备下要上网的设备需要ping一次家庭网关以建立链路刷新邻居表,登录管理页面状态,获得家庭网关的ipv6地址,然后macos或者Linux使用ping6命令ping即可。
windows使用ping -6命令。
