Nested ESXi Network Issue

[valntyn82]

I have two nested ESXi 6 machines running in a vCenter 5.5 Environment.  They are on and Isolated Standard vSwitch with a Windows 7 machine.  The Windows 7 machine can ping both of the ESXi 6 machines, but the ESXi 6 machines cannot ping each other.  Is there something simple I am missing??  Have been all over the internet trying to figure this out....

Any help would be greatly appreciated.  Need a test lab to start studying for VCP6 Certifications....

I stopped searching for the problem between Virtual ESXi Hosts and asked, "what if this problem existed between two Physical Host machines..."

Turns out the MAC Address was duplicated on the Management vmknic and not changed during the Clone process.

Thanks for your interest in this issue.

I suspected that you have cloned the ESXi VM and because of this I asked if you install the ESXi from scratch, cause clone ESXi without proper preparation can really cause problems.
