I've been reading extensively about VNET jails (using bridge & epair). I've learned quite a bit. There is one line about this in the handbook which is flat out wrong. "With the bridge created, it will be necessary to attach it to the em0 interface by executing the following command:" (emphasis mine) The following pictorial is correct but in fact you are creating the virtual bridge and attaching the physical em0 interface to the virtual bridge interface. There is a difference even if it looks subtle.shurik ok I see. So I assume that if I use the interface with vnet (to isolate) I will get all the features. I will try. Thans for your answer
