This object is a security feature that allows the
control of packets sent from specific source addresses.
If this object is set to forward (2), this port will
forward only those packets sent from addresses listed
in the static forwarding table for this port. If this
object is set to block, this port will block every
packet sent by a station whose address is listed
in the static forwarding table for this port. Note,
these actions are taken by this port after it receives
a packet from the network. This does not apply to
packets it forwards to the network.
