For source or destination IP address, you can define a single IP address (4.3.2.1) or
a range of IP addresses (4.3.2.1-4.3.2.254). An empty implies all IP addresses.
For source or destination port, you can define a single port (80) or a range of ports
(1000-1999). Add prefix "T" or "U" to specify TCP or UDP protocol. For example,
T80, U53, U2000-2999, No prefix indicates both TCP and UDP are defined. An
empty implies all port addresses. Packet Filter can work with
