Hopefully then you'd get an owned device in the zone, but still not an owned stack where you can go promiscuous, change routes, etc. It may still be the limit... Maybe you can't even set an ip address on the delegated vnic from inside the zone.

Oh my...

You're using a shared-stack zone.  I didn't know people still did that...

ISC DHCP needs full DLPI-ish access to the NIC in question.  I run ISC DHCP in a zone, but it's an exclusive-stack zone.  I'd take Jim's advice first if you're really intent on using a shared-stack zone.  I can't guarantee it'll work, but you certainly cannot run ISC DHCP without having a full NIC available.

Sorry,
Dan
