Packet Filters
The AWK-1100 provides layer 2 (Ethernet Type Filters), layer 3 (IP Protocol Filters), and layer 4
(TCP/UDP Port Filters) filtering capabilities. The configuration processes for the filters are
similar.

Ethernet Type Filters
The filed
Ethernet type
of the MAC (Media Access Control) header of a packet incoming from the
WLAN or Ethernet interface is inspected for filtering. As a rule, specify the hex-decimal Ethernet
type number and give the rule a name.
IP Protocol Filters
The protocol, source address, and destination address fields of a packet incoming from the WLAN
or Ethernet interface is inspected for filtering. As 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 192.168.127.253 and the source subnet mask field is 255.255.255.0,
the resultant source IP address range is 192.168.127.0 to 192.168.127.255.
