My Ubuntu is the guest OS running on a windows host. NAT is used and port forwarding has been added. All access to host on port 3000 should be forwarded to guest on the same port.
But that port can be only accessed on guest machine but not accessible from host machine.
With bridged network setting, there is no trouble. But my concern is that when I work offline(no internet connection) with my host machine, I can't access the guest via that port number any more. I've tried to disable the connection on host, then can't connect the port 3000.
What might be wrong with my installation and default NAT configuration(v4.3.20)?
