Docker network on MacOS broke applications using dynamic port connection.

[johntheteam]

Description

On MacOS, docker use gateway.docker.internal (192.168.65.1) and host.docker.internal(192.168.65.254) to talk to the host and other containers. But this made any applications using dynamic port broken.

Process: Host talk to container's port of 9001 to register a connection to talk back on its port of 9003 The container took the incoming traffic's IP(gateway) as the outsider IP (host), when it talks back, it can't connect.

Possible Solution: If docker can redirect any traffic from gateway to host, it probably can solve the problem.

Reproduce

Create an application to do the same thing in the process described in the description.

Expected behavior

Expect the container can talk via dynamic ports with the host.
