Win10 Bridged wired LAN disconnection

[DenisF]

Hello,
With VB 6.0.4 and Win10, when I disconnect-reconnect (or direct connected device reboot) wire on a bridged LAN, guest cannot reconnect.
Even if I disconnect-reconnect (with tool button), guest cannot discuss with wired device.
To get it restart, I have to change Promiscuous Mode in network setting or uncheck-recheck "VirtualBox NDIS6 Bridged Network Driver" in adapter property.
This driver should restart on wired event in adapter.

Here lines reported in VBox.log file:

Code: Select all

01:56:21.649569 NAT: Link down
01:56:24.649642 NAT: Link up
01:56:24.654579 NAT: DNS#0: 192.168.43.1
01:56:24.672781 NAT: DHCP offered IP address 10.0.2.15

But it's not on NAT adapter but bridged one.

We need to see a complete VBox.log, from a complete VM run, where the problem occurs:

• Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Hello,

Here the log and what I do:

00:05:00 Wire Disconnect => Lost Connection
00:10:00 Wire Reconnect => No Connection
00:15:00 Bottom ToolBar Menu Disconnect => No Connection
00:16:00 Bottom ToolBar Menu Reconnect => No Connection
00:17:00 Setting Change Promiscuous Mode => Connection refound

00:20:00 Wire Disconnect => Lost Connection
00:25:00 Wire Reconnect => No Connection
00:27:00 Drivers reload => Connection refound
00:30:00 Stop VM

Hope these are enough for you.

You have 4 NICs in the guest. Can you simplify the scenario so that if focuses on the problem? Do you disconnect all NICs? I see the Bridged-over-Ethernet being disconnected (if I'm not mistaken), so please disable/remove the other adapters and focus on this one.

Do you also get the problem in the rest of the adapters, or only on this one?
