7.3 Security
Your Router can be secured with incoming or outgoing IP Filtering. This allows you to control whether data can enter or leave via
the router.
7.3.1 IP Filtering
The IP Filtering screen sets filter rules that limit incoming and outgoing IP traffic. Multiple filter rules can be set with at least one limiting
condition. All conditions must be fulfilled when individual IP packets pass filter.
Outgoing IP Filter
The default setting for Outgoing traffic is ACCEPTED. Under this condition, all outgoing IP packets that match the filter rules will be
BLOCKED.
To add a filtering rule, click the Add button. The following screen will display.
