Ethernet Type Filters
Fig. 53 Ethernet type filters settings.
The Ethernet type filed of the MAC (Media Access Control) header of a pack-
et incoming from the WLAN or Ethernet interface is inspected for filtering. In
a rule, specify the hex-decimal Ethernet type number and give the rule a
name.
IP Protocol Filters
Fig. 54 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 hexadecimal 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 (desti-
nation) 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.
