After configuring a manual MAC address on a MAC based license server I received a error message:

The MAC Address entered is not in the valid range. Valid values are between 00:50:56:00:00:00 and 00:50:56:3F:FF:FF:FF

Error message:

Solution:

Without additional setting in the .VMX config file you won’t be able to assign a static MAC address in the range your require. To disable mac address checking before boot add the following line in the .VMX file.

ethernetX.checkMACAddress = “false”

Re-upload the .VMX config to the datastore and add the virtual machine to the inventory:

– Turn off your VM;
– Open Virtual MAC Tool;
– Connect your ESX host or VC;

– Select the VM and vNIC/Network you want to change the MAC address
