仅在本地 WLAN 网络（子网）中路由 ipv6

我有一台 Gentoo Linux 机器，通过路由器的 DHCP 获得了 V6 地址。有 V4/V6 网络。对于 DHCP，我使用 dhcpcd 并进行以下配置：

duid
persistent
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option interface_mtu
require dhcp_server_identifier
slaac private
noipv6rs

interface eth0
  ipv6rs
  ia_na

interface wlan0
  noipv6rs
  noipv4
  ipv6only

我尝试创建一个仅用于内部无线 v6 网络的路由器。

我尝试执行以下操作：

  1. 从 v6 网络为 wlan0 分配静态地址：

    # ip addr show wlan0
5: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1480 qdisc mq state UP group default qlen 1000
    link/ether 50:3e:aa:54:c2:c5 brd ff:ff:ff:ff:ff:ff
    inet6 2001:470:xxxx:1000::1/64 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::b614:22ce:a510:66e3/64 scope link
       valid_lft forever preferred_lft forever

  2. 添加 dnsmasq 巫师配置：

    interface=wlan0
listen-address=2001:470:xxxx:1000::1
no-resolv
server=2001:470:xxxx::1
local=/subnet1/
domain=subnet1
dhcp-fqdn
enable-ra
dhcp-range=::100,::1ff, constructor:wlan0, ra-names, 64, 12h
log-queries
log-dhcp

客户端有 V6 地址，但无法访问互联网。我可以从 Gentoo 机器 ping wlan0 客户端，但无法从 wlan0 和客户端 ping 全局地址。

# ping6 google.com -I wlan0
connect: Network is unreachable

我应该为 wlan0 添加一些静态路由吗？

当前路线表：
