  前提:所有设备接在路由器lan口,路由器wan口接光猫lan口。每次光猫重新拨号,后面所有设备获得的固定ipv6地址后64bit不变,前64bit都会变。临时ipv6地址的前64bit同固定ipv6地址一致,后64bit每48小时都会变一次。
  情况:我在路由器上使用sharealiddns,为后端的nas提供ipv6 ddns时,发现sharealiddns识别的ipv6地址一会是固定ipv6地址,一会是临时ipv6地址。同时,我已经打开路由器上的ipv6防火墙功能,使用固定ipv6地址设置了如下这样的规则,允许指定端口55555传入nas。不好设置临时ipv6地址的规则因为它每48小时变一次。

  问题:防火墙只好设置允许访问固定ipv6地址的传入,不太好设置允许访问临时ipv6地址的传入,而sharealiddns为后端nas提供ipv6 ddns服务时,在将ddns绑定在临时ipv6地址上的时候,传入连接无法通过防火墙。不知如何设置sharealiddns让ddns一直绑定固定ipv6地址上?

nas的ipv6-ddns一直在变

解析记录见上图,1f86是固定地址,2e9a是这一段时间的临时地址。
