MacOS Host to OpenWRT Guest routing

Appreciate not strictly an OpenWRT problem but most likely a MacOS issue.

OpenWRT installed and working as VMWare Fusion guest on MacOS14. A Windows guest on the same network can use OpenWRT fine as a default gateway.

MacOS static default gateway set to guest. Tcpdump on guest shows no traffic received. For some reason MacOS is doing proxy arps for Internet destinations on the interface facing the guest.

I’ve read one other person try and do this and thinking is Apple broke this in MacOS 13. Just want to confirm this is doomed.

(I’m trying to attach to a cellular modem which Apple also deprecated native support for)

It is vmware network setup, if you allow mac change or promisc on vswitch ports. OpenWRT setup alone will not correct your overall vmware setup.
