IP Filtering
The router supports IP Filtering which allows you to easily set up rules to control incoming and outgoing Internet traffic. The router
provides two types of IP filtering: Outgoing IP Filtering and Incoming IP Filtering.
Outgoing IP Filtering
By default, the router allows all outgoing Internet traffic from the LAN but by setting up Outgoing IP Filtering rules, you can block
some users and/or applications from accessing the Internet.
To delete the rule, click Remove checkbox next to the selected rule and click Remove.
To create a new outgoing IP filter, click Add. The Add IP Filter-Outgoing page will be displayed.
Enter the following parameters:
