ARMBIAN 作为路由器配置 IPv6 网络失败
IPv6 fails on ARMBIAN ROUTER
前段时间弄了一个我家云，准备整一个轻量 NAS，结果老是掉盘，于是想弄成一个单臂软路由。IPv4 、科学上网及 VPN 服务器都成功了，可是 IPv6 网络却失败，请大佬帮一下忙。
I have a RK3328 box with armbian running on it. The box has only one NIC, and acts as a linux one-armed router. IPv4 network works normally, but IPv6 fails.
我参考了很多 PO 文，包括但不限于：
I had read a lots of pages, including:
https://help.ubuntu.com/community/ADSLPPPoE
http://www.routereflector.com/2016/10/enabling-ipv6-via-pppoe-on-a-telecom-italia-tim-link/
https://wiki.archlinux.org/index.php/IPv6_(%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87)

VLAN 划分 (VLAN division)
我家云只有一个网口，所以我加了一个支持 VLAN 的交换机，划分了两个 VLAN 。
There is only on NIC, so I connect the ARMBIAN box with a switch that support VLAN. The two subnet of eth0 on ARMBIAN box:
- eth0.1, LAN interface ；
- eth0.2, WAN interface;

我建议你还是换 OPENWRT

DopaminePlz OP @shikkoku Openwrt 有 IPv6 的，不过升级的话要重新刷机，也挺麻烦。另外，怎么说也是 Debian 类的系统应用多一些，也新一些吧？

WAN 口要配置 DHCPv6PD 都不知道要怎么配。
