3.6.1.2. IP Protocol Filters 
 
Fig. 55. 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 protocol 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 resultant 
source IP address range is 192.168.0.0 to 192.168.0.255. 
3.6.1.3. TCP/UDP Port Filters 
 
Fig. 56. 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).
