ipv6

NAT

参考西北工业大学校园网openwrt(LEDE)固件下IPv6 NAT
系统版本

OpenWrt 19.07.8, r11364-ef56c85848

安装

opkg install ip6tables kmod-ipt-nat6

wan6默认能获得ipv6地址即可

lan服务器模式,这里使用tuna的DNS2001:da8::666

查看ipv6网卡配置

root@OpenWrt:~#  ip -6 route |grep "default from"
default from 2400:dd01:1026:127::/64 via fe80::4277:a9ff:fef5:6e01 dev eth0.2  metric 512

配置转发

#指定网关
ip -6 r add default via ` ip -6 route |grep "default from" | awk 'NR==1{print $5,$6,$7}'`
#配置转发
ip6tables -t nat -A POSTROUTING -o `ip -6 route |grep "default from" | awk 'NR==1{print $7}'` -j MASQUERADE

路由器下面的设备就可以访问ipv6了

开机自启

cat > /root/nat6.sh << EOF
#指定网关
ip -6 r add default via ` ip -6 route |grep "default from" | awk 'NR==1{print $5,$6,$7}'`
#配置转发
ip6tables -t nat -A POSTROUTING -o `ip -6 route |grep "default from" | awk 'NR==1{print $7}'` -j MASQUERADE
EOF
chmod +x /root/nat6.sh
