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 Scheduling Rules, and give user more flexibility on

Access control. For Detail, please refer to Scheduling Rule.

Each rule can be enabled or disabled individually.
