IP Protocol Filter

The AWK-5222’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-5222 provides 8 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.
