3.6.1.2. IP Protocol Filters

Fig. 52. IP protocol filters settings.

The protocol, source address, and destination address fields of a packet incoming from the

WLAN or Ethernet interface is inspected for filtering. In a rule, specify the hex-decimal pro-

tocol number, source IP address range (Source IP Address AND Source Subnet Mask), and

destination IP address range (Destination IP Address AND Destination Subnet Mask).

A source (destination) IP address range is determined by performing an AND operation on

the source (destination) IP address field and the source (destination) subnet mask field. For

example, if the source IP address field is 192.168.0.1 and the source subnet mask field is

255.255.255.0, the result source IP address range is 192.168.0.0 to 192.168.0.255.

3.6.1.3. TCP/UDP Port Filters

Fig. 53. TCP/UDP port filters settings.

The destination port field the TCP or UDP header of a packet incoming from the WLAN or

Ethernet interface is inspected for filtering. In a rule, specify the decimal Destination Port,

Protocol type (TCP/UDP), and the name of the higher-level protocol (Application Name).
