Thanks for the quick reply.

That looks very cool :)

Just to understand better because the instructions are not clear on that.

Suppose I install the package and add
engine-config -s 
UserDefinedVMProperties='previousProperties;macspoof=^(true|false)$' 
--cver=3.3

what will be the default action for my VMs? Filter or not filter?
So I gave to alter EnableMACAntiSpoofingFilterRules as well?

I mean do I have to explicitly define macspoof=true on all the VMs 
except the VMs I don't need filtering
or the opposite -> filter by default and set macspoof=false in the VM I 
don't need filtering?

I guess the same applies for VNIC.

What about conflicting values between VM and VNIC. Which has precedence 
over the other?

Thanks
