IP Protocol Filters
The AWK-1137C's IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with
specified IP protocol and source/destination IP addresses.
The AWK-1137C provides 32 entities for setting IP protocol and source/destination IP addresses in your
filtering policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source
IP or the Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a
range of IP addresses to accept or drop. For example, "IP address 192.168.1.1 and netmask 255.255.255.255"
refers to the sole IP address 192.168.1.1. "IP address 192.168.1.1 and netmask 255.255.255.0" refers to the
range of IP addresses from 192.168.1.1 to 192.168.255. Remember to check the Active check box for each
entity to activate the setting.
