开日志发现关键，run out先不管
那每当我从外网测试内网IPV6的时候就会出现下面的Warning
高手指导一下怎么解决，应该解决这个，网络就通了syslog: Ignoring non-LinkLocal MLD from :: received on br0/33

给各位认真研究问题的一个小福利，上面的问题虽然暂时没解决，但是我发现一个明显提升IPV6稳定性的设置方法，任何光猫xml文件里调整这几个值，如下：

基本上IPV6就稳定不掉了，设备更新、获取IPV6地址速度也超快，具体这几个值什么作用呢？自行搜索一下，就不解释了。
电信默认的值太大，导致IPV6经常性的不稳定。

  <Value Name="DHCPV6S_REBIND_TIME" Value="120"/>
  <Value Name="DHCPV6S_RENEW_TIME" Value="60"/>

<Value Name="V6_ADVDEFAULTLIFETIME" Value="60"/>

  <Value Name="V6_MINRTRADVINTERVAL" Value="30"/>
<Value Name="V6_MAXRTRADVINTERVAL" Value="40"/>

折腾半天，又找到一张桥接路由表了，看样子防火墙还真不止一个，但是这个表接口太多，不敢乱动，头大试了都加上ACCEPT不行，-t brouter 里全加DROP或ACCEPT也不行，还要继续研究

说到桥接表，那必须要有接口信息才好研究，接口信息如下：

理论是研究完了，
理论解决办法：就是要把公网接口ppp0和内网接口br0，桥接起来
那如果做IPV6路由也行，但IPV6是动态的，牵涉太多，所以还是桥接方案简单，因为2个接口是固定不变的
再要研究一下桥接表。

佩服楼主，我的PT928G也管不了ipv6防火墙，进Telnet查看ip6tables-save，发现有一条-A FORWARD -i ppp1 -j DROP，于是执行
ip6tables -D FWD_FIREWALL -i ppp1 -j DROP
终于正常了
