- The default policy of "ACCEPT" allows all packets to/from
- interfaces in the zone to be forwarded, while the (*low priority*)
- reject rule blocks any traffic destined for the host, except those
- services explicitly listed (that list can be modified as required
- by the local admin). This zone is intended to be used only by
- libvirt virtual networks - libvirt will add the bridge devices for
- all new virtual networks to this zone by default.
