有需要的朋友可以按照我的方法开启IPv6支持，但是一定要看好系统版本并且做好备份，本教程仅供有一定基础的朋友参考，本人不对任何系统崩溃及数据丢失、损坏负责。
设备：F2-210
版本：4.2.08-2101111540-P1.04 （4.2.08+P1.04补丁），本人系统经过大量修改，如果原生系统不兼容可以留言
网络：路由器PPPOE拨号，开启DHCPv6，NAS自动获取IP、IPv6
主要用到以下三个文件：
/etc/network/interfaces 记得增加执行权限(chmod +x)
/lib/netifd/proto/dhcpv6.sh 记得增加执行权限(chmod +x)
修改完后 service network restart/usr/share/udhcpc/default6.script
查看ip使用 ip addr 出现公网IPv6地址即可
