MAC Address Routing Issues

SmashSmash Newbie ✭
in Mid Range Firewalls

We have an NSA4700 that I've been trying to use MAC Address instead of IP address for some of our intra-vlan routing. I have this device at 10.0.14.3 that I set as a multi-homed MAC address, but it comes as unresolved within the Sonicwall firewall. If I change to its static IP, routing works immediately.

I've tested with several different MAC addresses, and I'm stumped as to why this is so broken. Is there something within the Sonicwall I need to be doing to keep this functioning, and has anyone either had luck with this approach or have they dealt with the same issues? Please let me know if I can provide any additional details.
