Hi,
I have VMWare vSphere ESXi 6.5 VM and Linux VM deployed on a physical ESXi 6.5. Both have identical network configuration - Linux VM is absolutely fine to access from anywhere in the network, but unable to access the VM with Guest OS ESXi
I can reach the ESXi VM from it’s physical system and from the Linux VM without any issue. I am also able to reach all systems from the ESXi VM. But packet drops when trying to reach the ESXi VM from any other system in the network.
Can anyone suggest what could be the potential cause here.
'Promiscuous mode' and 'Forget Transmits' are enabled for vSwitch on physical host.
