VNICs and VirtualBox doesn't go well together. The reason for this is
that VirtualBox doesn't know anything about the MAC address of the
VNIC, and thus doesn't forward traffic to that MAC address into the
virtual machine.
When you run tcpdump it will set the network interface in promiscuous
mode, which will drop the filtering of traffic intended to other
hosts, and the traffic to the zone will get through.

The best way I have found to solve this, is to create an extra network
interface in the VirtualBox configuration, and then assign that
interface to the zone instead of a VNIC. Then it will work as
expected.
