IP Protocol Filter
The AWK-3131A-M12-RCC’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-3131A-M12-RCC 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.

TCP/UDP Port Filter
The AWK-3131A-M12-RCC’s TCP/UDP port filter is a policy-based filter that can allow or filter out
TCP/UDP-based packets with a specified source or destination port.
The AWK-3131A-M12-RCC provides 8 entities for setting the range of source/destination ports of a specific
protocol. In addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or
both. The end port can be left empty if only a single port is specified. Of course, the end port cannot be larger
than the start port.
The Application name is a text string that describes the corresponding entity with up to 31 characters.
Remember to check the Active check box for each entity to activate the setting.

ATTENTION
Be careful when you enable the filter function:
Drop + “
no
entity on list is activated” = all packets are allowed.
Accept + “
no
entity on list is activated” = all packets are denied.
