Port number comparisons

A ﬁlter can also use a comparison option to evaluate a packet’s source or destination port number. The

comparison options are:

Not Equal To: For the ﬁlter to match, the packet’s port number cannot equal the port number speciﬁed in the

ﬁlter.

Less Than: For the ﬁlter to match, the packet’s port number must be less than the port number speciﬁed in the

ﬁlter.

Less Than or Equal: For the ﬁlter to match, the packet’s port number must be less than or equal to the port

number speciﬁed in the ﬁlter.

Equal: For the ﬁlter to match, the packet’s port number must equal the port number speciﬁed in the ﬁlter.

in the ﬁlter.

Greater Than or Equal: For the ﬁlter to match, the packet’s port number must be greater than or equal to the

Other ﬁlter attributes

■ The ﬁlter’s order (i.e., priority) in the ﬁlter set

■ Whether the ﬁlter is currently active

■ Whether the ﬁlter is set to forward packets or to block (discard) packets
