Wi-Fi device IE-WL-BL-AP-CL  Web Console Configuration 
3-39 
The IE-WL-BL-AP-CL 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 192.168.1.255.  
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. 
TCP/UDP Port Filters 
The IE-WL-BL-AP-CL’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 IE-WL-BL-AP-CL 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.
