Enhancing security
Discarding needless packets
(inbound filter)
The inbound filter enables incoming packets to be discarded or blocked based on their source or
destination IP addresses, protocols, and port numbers. Compared with the policy filter, this filter can
dispose of needless packets at an earlier stage, without putting much load on the product. Note that
the inbound filter can be set for each interface.
