15304	Windows 10 host seems to be filtering network traffic for guests	Rafcio		"I have the same situation happening on multiple Windows 10 hosts. They were all upgraded from Windows 7 and VirtualBox has been reinstalled on one of them to test the possibility that the upgrade broke it. Unfortunately, re-installation of VBox didn't help. This is also happening with multiple guests (Windows 7, XP), so it's pretty much widespread. VBox is unusable on Windows 10 hosts.

It looks like there is some kind of network filtering happening. It's not that networking is not working at all on the guests. There seems to be things that work (i.e. nslookup works) and things that don't work (i.e. ping). If a start a browser I can get to some sites, but most of them don't work. It looks like http is being filtered out, but https is actually working. When I move the VM to Windows 7 host everything is working perfectly, so the problem is clearly on the host side."	defect	closed	network	VirtualBox 5.0.16	invalid			Windows	Windows
