How to change external interface MAC address ?

Hello David,

you got the correct setting. BUT if Virtual MAC works or not depends on the used NIC / driver implementation. It' s only guaranteed to work with Sophos Appliances, I think.

Thank you Alexander.

if I wanted to try ahead, is there any way to see if it works like below:

1- set the Virtual MAC

2- reboot

3- run ifconfig locally

Or

3 - ping the UTM, then run ARP -A to check the MAC discovered

Also, would the Virtual IP replace the HW MAC or would the NIC report both ?

Worst case scenario I can install an HP NC7170 card (Intel 82546EB)....

Hey David,

your steps make sense to me. As third step I would ping and ARP.

The virtual IP should replace the HW MAC.
