   All firewalls in FreeBSD can, actually. It's part of the stateful
inspection feature. The only thing they lack is a match parameter
based on the timer.

If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
