macOS bigsur virtual machine version 12.2.0 doesn't respond to remote ping when configured to NAT.

Hi, 

I've upgraded my fusion to version 12.2.0, and my VM that run macOS bigSur is now configured to hardware version is 19 under compatibility. my physical machine also runs the same OS version. 

However, since the upgrade I can only get response to ping to my physical machine (ip 192.168.214.1) with the bridge interface below, but when I try ips outside the subnet it doesn't get any response (i.e. ping 8.8.8.8) although I've checked that it's working on wiki mode.

Any idea if it's a known issue and how can I debug it ?

I have the same problem. VMs can no longer see the external network (access the Internet) with NAT. I tried also testing on a further VM at hardware version 18 before upgrading to hardware version 19 with the same result.

Actually NAT does work. The gateway has changed from ".1" to ".2". Which would have passed un-noticed if Fusion were still able to provide DHCP on Big-Sur/Monterey,

However, can no longer route between private networks as was possible with a previously working configuration.
