有 Docker 真的是啥都能折腾。(仔细看，不要直接复制，照着自己的环境改)
我选用的 Docker 镜像是 sulinggg/openwrt 的 ImmortalWrt。
准备
首先拉取镜像,根据自己的平台架构拉取，我的是 X86_64 的。
docker pull sulinggg/openwrt:x86_64部署
查看网卡名称。

根据你的主路由网段和网卡名称，创建 Macvlan 网络。我的网段是 192.168.123.0/24 ，网关是 192.168.123.1 ，网卡名称是 enp1s0。
docker network create -d macvlan --subnet=192.168.XXX.0/24 --gateway=192.168.XXX.1 -o parent=网卡名称 macnet创建完成网卡后就可以启动容器了
docker run --restart always --name openwrt -d --network macnet --privileged sulinggg/openwrt:x86_64 /sbin/init进入容器控制终端
docker exec -it openwrt bash修改openwrt网络
vim /etc/config/network其中 option ipaddr '改成192.168.XXX.2'
option gateway '改成192.168.XXX.1'
option dns '改成192.168.XXX.1'
重启网卡
/etc/init.d/network restart然后就可以访问 openwrt 了
如果无法上网，关闭主路由的offload TCP/UDP for WLAN
