2.19.1.4 User Filtering (AU Only)
User Filtering Option The User Filtering Option disables or enables the User Filtering
feature. The following options are available:
 Disable: No filtering.
 IP Protocol Only: Only IP Protocol packets pass.
 User Defined Addresses Only: Only IP frames from/to IP
addresses included in the User Filter Addresses list pass.
 PPPoE Protocol Only: only PPPoE messages pass (Ethernet type
0x8863 and 0x8864).
Filter IP Address Ranges The Filter IP Address Ranges table enables defining/updating up to 8
IP address ranges to/from which IP frames are to pass if the User
Defined Addresses Only option is selected in the User Filtering
Option parameter.
IP filtering can be defined using a range that includes either a start
and end address (example: 192.168.1.1 to 192.168.1.255), or a
subnet using base address and a mask (example: 192.168.1.1 mask
255.255.255.0). The table contains the following columns:
 IP Start: The start IP address for the specified range or the base
IP address for the subnet
 IP End/Net Mask: The end IP address for the specified range or
the net mask for the subnet
 Range/Subnet: Specifies the type of definition
Use the following buttons to edit the table:
 Add: Adds a new filter IP address range
 Revert: Removes a newly added filter IP address range
 Delete: Deletes a preexisting filter IP address range
 Delete All: Deletes all filter IP address ranges
DHCP Unicast Override
Filter
When user filtering is activated, unicast DHCP messages are filtered
out; therefore the unit cannot communicate with the DHCP server.
The DHCP Unicast Override Filter option enables users to overcome
this problem. When enabled, unicast DHCP messages pass,
overriding the user filtering mechanism.
