# 开启混合
# wlp0s20f3: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST>  mtu 1500
# 出现 PROMISC 即成功
ifconfig wlp0s20f3 promisc

# 关闭混合
ifconfig wlp0s20f3 -promisc

系统转发

sudo vim /etc/sysctl.conf
# 添加
net.ipv4.ip_forward = 1
# 确认
sudo sysctl -p /etc/sysctl.conf

创建Docker网络

# 创建网络
docker network create -d macvlan --subnet=192.168.8.0/24 --gateway=192.168.8.1 -o parent=wlp0s20f3 macnet

# 查看docker网络列表
docker network list

# 查看配置
docker network inspect macnet

# 树莓派额外配置
# 否则会报macvlan不支持
sudo apt install linux-modules-extra-raspi
sudo reboot
