Do I read it well ? It seems that not matched tag are still decoded in nom= atch hook : https://github.com/freebsd/freebsd-src/blob/373ffc62c158e52cde86a5b934ab4a5= 1307f9f2e/sys/netgraph/ng_vlan.c#L576-L599 Beno=C3=AEt > Hi Lutz, > > I tried your solution, so far it works (once i figured it was "link0" and= not "0" :) . But the notmatch bridge will only receive the native vlan it = seems. Is there a way to get all the other tags, ie not filtered, as well? > > Beno=C3=AEt > > ------- Original Message ------- > On Tuesday, April 26th, 2022 at 12:08, Benoit Chesneau benoitc@enki-multi= media.eu wrote: > > > > > I am trying > > > > `mkpeer vlan0: bridge 100`but so fat it is returningan error.

I woul= d like to bridge the vlan 100 and 200 but also have a bridge for the "nativ= e" vlan 1.
