0.环境

光猫--->主路由器--->5GWiFi--->树莓派--->交换机--->电脑

1.安装依赖

提前连接好WiFi！！！

apt-get install brctl dnsmasq radvd ndp6

2.配置DHCP与radvd以及nat转发设置

vi /etc/dnsmasq.conf

dhcp-sequential-ip
 
dhcp-range=10.96.181.10,10.96.181.240,255.255.255.0,12h
dhcp-range=fd00::22, fd00::44, 64, 12h
resolv-file=/etc/resolv.dnsmasq.conf
enable-ra

vi /etc/radvd.conf

interface br0
{
     AdvSendAdvert on;
     IgnoreIfMissing on;
     prefix 2001:db8:1:0::/64
     
    {
       AdvOnLink on;
       AdvAutonomous on;
       AdvRouterAddr on;
    };
};

vi /etc/sysctl.conf

 net.ipv4.ip_forward=1
 net.ipv6.conf.all.forwarding=1
 net.ipv6.conf.all.proxy_ndp=1

vi /etc/npd6.conf

prefix=2001:db8:1:0::
interface = wlan0

ralogging = off
listtype = none
listlogging = off
collectTargets = 100
linkOption = false
ignoreLocal = true
routerNA = true
maxHops = 255
pollErrorLimit = 20

3.建立网桥，配置ipv6穿透

#!/bin/sh
brctl addbr br0
brctl addif br0 eth0
brctl stp br0 yes
ifconfig br0 10.96.181.1 netmask 255.255.255.0 up
ifconfig eth0 0.0.0.0 up
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
ifconfig br0 inet6 add 2001:db8:1:0:33fa:24b1/64					#网桥ipv6地址
ip6tables -t nat -A POSTROUTING -s 2001:db8:1:0::/64 -j MASQUERADE #内网IPV6前缀，与/etc/radvd.conf一致
ip -6 route add 2000::/3 via fe80::6609:80ff:fe71:a3f4 dev wlan0	#广域网IPV6网关
ifconfig eth0 0.0.0.0 up

注意设置广域网ipv6网关
注意eth0不要设置ip否则无法上网

4.检查服务并重启

service dnsmasq start
service radvd start
service npd6 start

将第三步设置开机自动执行即可
