支持IPv6这事情不一定非得要路由上配，局域网内只要有Linux机器能用IPv6就行。 这种事情做之前，对于完全不会的人和会的人都很简单，但对我这种稍微懂一点的，还没做可能就先想多了。 测试环境 公司 路由：TP-Link某老旧企业路由，不支持IPv6 Linux：Debian Jessie, 服务主机，兼顾dns，dhcp等等服务，LAN接口eth0 网络：北京联通家庭光纤 PPPoE IPv6 服务：Tunnel Broker 其他软件：dnsmasq, dhcpd Incoming search terms:wireguard设置ipv6 dhcp-baijiahaoaccept7cnanybodyrx3LAN怎么成为IPv6stoodwx7企业路由ipv6局域网IPV6开启 RADVD维盟路由器 ipv6Link to this post!
家里配了IPv6的tunnel，所有设备也把IPv6配上了，结果导致dns解析时默认v6的解析结果会被高优先级拿出来用。 Debian更新时，国内镜像就灾难了。 应对这种方案，需要临时禁用IPv6，方案是：
|
1 |
echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6 |
也可以针对特定设备关闭。 这个方案在wifi重连之后还得再来一次。 否则就得彻底禁用IPv6。 改 /etc/sysctl.conf
|
1 |
net.ipv6.conf.all.disable_ipv6 = 1 |
|
1 |
sysctl -p |
