Blacklist will prevent all listed devices from accessing the module and using the
radio link.
Whitelist will allow devices with the MAC addresses listed to communicate with
the module and utilize the radio link. All other devices are blocked.

IP Address Filter Configuration:
The IP filter allows can be used to permit or deny network access to specific devices through the use of Blacklists
(blocking of traffic that matches a rule) and Whitelists (allow traffic that matches a rule).
The IP filter entry will match either source or destination address in the packet. That is, if either the source or destination
IP address falls within the address range specified in the rule, the packet is matched and will be discarded (Blacklist) or
allowed (Whitelist).
If the protocol is specified, the protocol of the packet must also match. If the protocol is TCP or UDP the source or
destination TCP/UDP can also be inspected. If the IP address and protocol matches and the source or destination port
number falls within the range specified, the packet is matched.
Note: Configuration pages use TCP protocol on ports 80 and 443. Create Whitelist rules specifying
the configuration PC's IP address, with TCP protocol, ports 80 and 443.
ARP Filter Configuration
ARP (Address Resolution Protocol) is a broadcast message and is primarily used for identifying MAC addresses when
only the IP or some other Network Layer address is known.
On large networks, you generally tend to get a high proportion of broadcast messages. ARP filters are useful for reducing
broadcast traffic that is generated on the wired side of the network on to the wireless network. This is done by only
allowing ARP requests for the devices that are on the wireless network, or blocking ARP requests for high use addresses.
This means that all other ARP requests for devices on the wired network will not be passed over the radio. As the 450U-E
Blacklist will prevent all listed devices from accessing the module and using the radio
link.
Whitelist will allow devices with the IP addresses listed to communicate with the
module and utilize the radio link. All other devices are blocked.

IP Address Min,
IP Address Max
These set the range of IP addresses. All addresses within the specified range are
affected by the rule.
Port Min,
Port Max
When the protocol is set to TCP or to UDP, this is the range of port addresses to
which the rule applies. When protocol is set to All or to ICMP, these settings have no
effect.
Protocol
This chooses the protocol to which the rule applies. The rule can apply to Any
protocol (All), or to only one of TCP, UDP, or ICMP (Ping).
