in pf.conf(5) the GRAMMAR shows:
      ifspec         = ( [ "!" ] ( interface-name | interface-group ) ) |
                       "{" interface-list "}"

So you could do "set skip on { lo0 vif0 vif1 }" for explicit, or you
use interface-group, alas "set skip on vif". If that "one" interface
is e.g. vif7 within vif(4) this MIGHT go: "set skip on { vif !vif7 }".

Hi Philipp,

Ok, so the "!" is a NOT operation ?

If that is the case, could I use:

    ext_if = "em0"

    set skip on !$ext_if

... with the idea that this skips all interfaces (virtual or otherwise) 
_EXCEPT_ em0, which is the real Ethernet NIC that I want to perform 
filtering on ?

Thanks,
