Happy new year!
I'm facing some issues on my test environment, which is as follow:
Now the ESXi part:
The issue is that the nested VMs can only talk to each other or the console, but not to the host laptop or other VMs, except the ESXi itself.
I've tried the follownig with no chance:
The only thing that works a bit is DHCP, although it seems the acknowledgement never reach the nested VMs. However, they still get a proper IP address, but after that are not able to receive any ARP traffic. If manually adding some arp entries and can see ICPM request on vnet0 (the bridge) from nested VMs to other machines and the corresponding replies. If pinging the other way I only see the requests, meaning the traffic is not forwarded to the nested VMs.
The ESXi vswitch is configured to accept promiscuous mode, MAC adress changes and forged transmits.
Thanks in advance if anybody has a clue
I didn't think about this one because I could see vnet0 properly going into promiscuous mode and nothing in my syslog about vmnet0... I changed the rights on /dev/vmnet0 as described in your kb link and now it works fine.
You made my day, thanks a lot!
