    这是一个创建于 2284 天前的主题,其中的信息可能已经有所发展或是发生改变。
    dhcpv6 服务端为 dnsmasq 配置如下:

    dhcp-authoritative
    domain-needed
    localise-queries
    read-ethers
    bogus-priv
    expand-hosts
    server=/lan/
    dhcp-leasefile=/tmp/dhcp.leases
    resolv-file=/tmp/resolv.conf.auto
    addn-hosts=/tmp/hosts
    conf-dir=/tmp/dnsmasq.d
    stop-dns-rebind
    rebind-localhost-ok
    dhcp-broadcast=tag:needs-broadcast
    dhcp-range=lan,192.168.1.100,192.168.1.249,255.255.255.0,12h
    no-dhcp-interface=eth0.2
    dhcp-range=fd11:4401::100, fd11:4401::200, 64, 12h
    enable-ra

    win10 1803 未启用 hyperV 时可正常获取 ipv6 地址,启用之后并新建 external vswitch,宿主机和客户机都会通过这个 vswitch 和物理网路桥接来和外部网络通信。此时 vswitch 无法获得 ipv6 地址,但 ra 正常可以获得 ipv6 前缀长度和缺省路由以及 dns 等等。而且此时客户机也正常,可以和外部 ipv6 通信。

    用以下步骤尝试解决未果:
    1. netsh interface ipv6 reset 重置网络配置
    2. 完全关闭 win10 内建防火墙

    通过抓包发现宿主机可以正确发出 dhcpv6 的请求,但好像没有收到回应一样多次重试请求:

    楼主这个问题后来解决了吗?我碰到了同样的问题,通过 wireshark 可以看到发出了 dhcpv6 请求而且也收到回复,但是一直在重发。

    @PublicDNS 没有解决,目前只能手动。奇怪的是很少有人反应这个问题,更没有 bug 提交。

    @404error 我升级到 1909 反而好了,宿主机可以拿到 ipv6 地址了。你把原来虚拟出来的 external vswitch 删掉重建一个新的试试。
