Airlink101 AR325W manual Example of using the Packet Filter

For source or destination IP address, you can define a single IP address (192.168.1.100) or a range of IP addresses (192.168.1.100-192.168.1.254). An empty field implies all IP addresses.

For source or destination port, you can define a single port (80) or a range of ports (1000-1999). Add the prefix "T" or "U" to specify TCP or UDP protocol.

For example: T80, U53, or U2000-2999. No prefix indicates both TCP and UDP are defined. An empty field implies all ports.

Packet Filter can work with Schedule Rule, allowing precise control of when the filters will be active. For more details about Schedule Rule, please see 5.5.6 Schedule Rule.

Each rule can be enabled or disabled individually by checking or clearing the corresponding Enable box for each rule.
