Host Only adapter stoped working on 6.1.30

Postby thar02 » 24. Nov 2021, 09:57

I updated my VirtualBox yesterday from 6.1.28 to 6.1.30.It still shows 6.1.28 on the about-box (Version 6.1.28 r147628 (Qt5.6.3)) but when I run "Check for updates" I get that I am on the most recent version.
The problem is that when I start my virtual machines that worked before the updates the network dont work between the physical mashine and the virtual hosts.
Between the virtual mashines it seams to work ok.
I can see in the change log that somthing was done with the "Host-only adapter".
Is it just me or can someone verify that there is a problem?

If you're using the Host-Only adapter, then there has been a change:

There is a new requirement for Host-Only networks since 6.1.28 that plugs a security hole. See https://www.virtualbox.org/manual/ch06. ... k_hostonly, at the end of the section, starting at "On Linux, Mac OS X and Solaris Oracle VM VirtualBox...".

Thanks scottgus1 for your help, You saved me a lot of hours :).
It seams that the allowed ip-range have changed and some of the vboxnet<n> was out of the scope.
So if someone else have the problem change the vboxnet<n> configurations to comply with the 192.168.56.0/21 range (Adapter and DHCP). Then it started to work again.

Great! Glad you're up and running.

FWIW adding the ranges one wants to use to the configuration file is also supposed to work.
