3.5.4.2 Incoming IP Filtering Setup
Click “Security”-->” IP Filtering”-->” Incoming” to show the following interface.
By default, all incoming IP traffic from the WAN is blocked when the firewall is enabled.
However, some IP traffic can be ACCEPTED by setting up filters.
The screen allows you to create a filter rule to identify incoming IP traffic by specifying a
new filter name and at least one condition below. All of the specified conditions in this
filter rule must be satisfied for the rule to take effect. Click 'Save/Apply' to save and
activate the filter.
And you must select at least one or multiple WAN interfaces to apply this rule.
