都是手动配置，不会dhcp自动

老哥 我这个 一键出来的宿主网卡怎么优化, 教程里面说的是

简单的说，vmbr0负责v4的独立IP，vmbr1负责复杂v4/v6的NAT，vmbr2负责v6的独立IP

我网卡当前的配置，好像无法分配小鸡独立的IPV6，

目前是 小鸡有内网V4V6但是 外网都是跟母鸡共享的V4V6

查看小鸡绑定的是虚拟网卡 vmbr1

这里我贴个我的配置，开了小鸡网卡用 vmbr1 之后，只需设置地址 2408:8763:0:ddd::3 下一台小鸡就 2408:8763:0:ddd::4 所有小鸡网关统一 2408:8763:0:ddd::2 这样没问题，内外能通，都能独立使用ipv6，没有做dhcp，如果做dhcp，也按照这个设置就行

你这样需要添加两个网卡，看起来怪怪的，我这样设置只需要添加一个 vmbr1 就有ipv4内网，ipv6内外网，方便而且又不会怪怪的

由于我没有使用你的dhcp功能，手动设置小鸡网卡为如下配置
