Please follow below steps to set your IP Filter:
• IP / MAC Filter Set Editing: Choose your IP / MAC Filter Set Index, Interface and
Direction options. Remember, Interface and Direction functions are affected with IP /
MAC Filter Set Index. EX: if your 1

Interface and Outgoing as Direction, so the list of 1
st
IP / MAC Filter will be PVC0
and Outgoing as their settings
• IP / MAC Filter Rule Editing: Select the IP / MAC Filter Rule Index (up to 6
numbers for each set index), select IP as a Rule Type and choose Active option.
As an example, Source IP Address is 192.168.1.10, Subnet Mask is
255.255.255.255, Destination IP Address & Subnet Mask is 0.0.0.0, Port
Number is 80. And, Protocol sets TCP. From this setting, it filters 192.168.1.14, so
it cannot access the web. Notice, each IP / MAC Filter Set Index can has up to 6
filters IP. At “Rule Unmatched” option, you must choose NEXT until the last filter IP
choose Forward.
• After every setting is done, click SAVE to continue next IP / MAC Filter Editing.
