in General Setup → MAC Address for Packet Duplication.

OUT: Specify the rule for filtering outgoing packets.

♦ Protocol – Specify the protocol(s) this filter rule will apply to.

♦ IP Address – Specify a source and destination IP address for this filter

rule to apply to. Placing the symbol "!" before a particular IP Address will

prevent this rule from being applied to that IP address. It is equal to the

logical NOT operator.

♦ Subnet Mask – Specify the Subnet Mask for the IP Address column for

this filter rule to apply to.

♦ Operator – The operator column specifies the port number settings. If the

Start Port is empty, the Start Port and the End Port column will be

= : If the End Port is empty, the filter rule will set the port

number to be the value of the Start Port. Otherwise, the

port number ranges between the Start Port and the End

Port (including the Start Port and the End Port).
