NLB cluster on Windows 2016

Hello!

I'm trying to setup NLB cluster from Windows 2016 Virtual machines, but after creating cluster i lost connectivity to (from) virtual machine, and of course NLB cluster is not working.  NLB cluster console and event log shows no errors and cluster shows as Converged.
Of course "Enable MAC address spoofing" is checked and NLB cluster is in unicast mode.
Then I created Windows 2012 R2 machine on the same HyperV host (Windows 2016) with the same settings and NLB cluster works as expected.
So anything other is needed to configure on Windows 2016? Any ideas?

Thanks.

M.
