Mac address

Hello

I have a device on the network with mac address xx:xx:xx:xx:xx:x1

I have a web based app that identifies the device by its mac address BUT I want the app to be able to see the device as mac address xx:xx:xx:xx:xx:x2 yet connect to the device on the LAN at mac address xx:xx:xx:xx:xx:x1

How can I do this, its similar to NAT routing with ports I would had thought ?

Thanks for any help

I never tried it, but “/interface bridge nat” looks like it could help you.
