I'm trying to solve a problem that's causing me a serious headache.
Please consider a lab environment for pure testing and self-training purpose based on nested virtualization.
I have a standalone physical ESXi 7.03 server with no vSphere implementation.
On the physical ESXi server I have 2 Port Groups.
On each Port Group I have a virtual ESXi 7.03 host and a VM (OpenWRT) configured as a firewall and DHCP server.
Inside each (virtual) ESXi host I have a Windows Server 2019 VM.
The Windows Server 2019 VM hosted by the (virtual) ESXi host on Port Group 1 obtains its IP address from the DHCP server and can successfully ping 8.8.8.8.
The Windows Server 2019 VM hosted by the (virtual) ESXi host on Port Group 2 cannot obtain any IP address from the DHCP server; assigning an IP address does not solve any problem and the VM cannot ping the default gateway neither any other host on the Port Group.
The (virtual) ESXi hosts and the Windows Server 2019 VM are created and installed in the same way using the same .iso files.
There is obviously some difference between the two Port Groups and/or among the VMs, but I spent a lot of time without finding it.
Can anybody please suggest the further checks I can do to troubleshoot and (hopefully) solve the problem?
Regards
