![]() the configuration of a gateway to reach a remote server.integration in a LAN (local area network).To illustrate this chapter, we will use the following architecture. Troubleshoot the network of a workstation. Objectifs : Dans ce chapitre, vous apprendrez à :Ĭonfigure a workstation to use a static configuration Ĭonfigure a workstation to use a gateway Ĭonfigure a workstation to use DNS servers In this chapter you will learn how to work with and manage the network.

Guests get an IP address, eventually ( good). Linux get zilch ( implementation specific?). OSX, Windows get APIPA addresses, eventually ( good). OSX, Windows get APIPA addresses ( good). This is the scenario that fails in your case, but not in mine, so I can't "confirm" your findings. Guests believe they still have an IP ( not good), but can't communicate ( confusing). All scenarios start with both of the host and the guest plugged/connected, with no problems in communicating with each other or the Internet. " Connect/Disconnect the wire" refer to the VirtualBox wire. Just so that we keep the terminology straight, " Pull/Plug the wire" refer to the physical connection. Whenever there are differences, they will be noted. I tried several scenarios, with three guests: OSX 10.9.5, Windows 7 x86 SP1 and Linux Mint 17.3 圆4. I have a MacBookPro, with both wired and wireless connections in the 10.0.0.# range. ![]() ![]() I took an interest in this, because I had a somewhat similar problem 3 years ago with VirtualBox 4.3: NAT cable_connected ignored when router goes down. I believe that the problem is that the guest does not get a "cable connected/disconnected" notification forwarded from the host. OK, there is definitely something funky going on, I'll agree with you. Is there anything I can try or should I submit a bug report? I'm surprised that I can't seem to find anything on this because all of my engineers who are running VirtualBox are experiencing this exact same problem. This leads me to believe the problem is on the host side and not the guest additions. * Powering down the VM and restarting it does not work. ![]() * Changing to a different bridged adapter (such as wireless) or a NAT adapter and then back to the original bridged adapter is enough to restore connectivity. VirtualBox Version: 5.0.X (don't remember when first observed) - 5.1.6Ībout a year ago, me and my colleagues started noticing a problem where a bridged network connection would work fine when a VM was started but unplugging the network cable and plugging it back in would result in VirtualBox never resuming the network connection on the guest. ![]()
