Network host on windows

[Enelg52]

Hi !
I just tried Exegol on a Windows 10 machine and I have a question. My container settings are saying that I'm using the host network. But the docker documentation says that it does only work on a Linux host. https://docs.docker.com/network/network-tutorial-host/
Is this a mistake ?

Indeed you are right, this particularity of docker desktop is not taken in consideration by exegol which still tries to create the container in host mode.
Could you do a docker inspect of your container to see the network configuration of the container?

This is what I got :

The subject will be clarified in the next release of Exegol (4.0.2).
It will no longer be possible to create containers in host mode from this version however it will now be possible to open ports (docker NAT) between the host and the container with the -p or --port parameter.
The port opening does not cover all the problems, however there is always the possibility to open VPN connections
