Host machine ip:192.168.123.2 Gateway:192.168.123.1
Adapter is enp3s0, so I create a docker network in host:
docker network create -d macvlan --subnet 192.168.123.0/24 --gateway 192.168.123.1 -o parent=enp3s0 -o macvlan_mode=bridge macnet
Run a container set IP
docker run --net macnet --ip 192.168.123.102 --name hd3 -it ubuntu bash
Container and Host machine ping Gateway 192.168.123.1 are all work.
But doesn't work between the container and the host.
Container:
ping Gateway is OK
ping Host isn't OK
Host:
ping Gateway is OK
ping Container isn't OK
Why and How can I communicate between the docker container and host machine?

docker run --network="host" Alternatively you can run a docker container with network settings set to host . Such a container will share the network stack with the docker host and from the container point of view, localhost (or 127.0.
By default, Docker provides two network drivers for you, the bridge and the overlay drivers. You can also write a network driver plugin so that you can create your own drivers but that is an advanced task. Inspecting the network is an easy way to find out the container's IP address.
Container networks run on software platforms, such as Docker, that can be run on the cloud. Container's efficiency comes from the fact they are self-contained. They use the bare minimum of software and resources to run and use a router to direct traffic instead of a switch.
In Docker, the host is a machine responsible for running one or more containers. Docker network host, also known as Docker host networking, is a networking mode in which a Docker container shares its network namespace with the host machine.
If you have a recent enough docker (18.03 and more), see, as mentioned here, if you can use:
host.docker.internal
That was first documented for MacOS as host, but should work on Windows host too.
