To be honest, we are fucking up the planet at an exponentially faster rate, so it is natural that mitigation solutions seems exponentially crazier.

There are people that believe that doing these crazy things will actually reverse the damage.

Then there are people like me who not only believe we are fucked but also believe that anything we do now is completely pointless as we are fucked either way so why bother.

You can use a bridge network or the host network.

In bridge network it is like a NAT host. With its own firewall settings.

In host network mode, it will just open the port it needs.
