Hi Christopher, Thanks for your solution. It does help a lot, but there's one problem. For example, DHCP server is not started for some reason and my computer's ethernet cable is plugged. Once dhcp server started, I can't get the IP unless I unplug and then plug the ethernet cable. Do you know how to solve this issue? Thank you.
