Incoming IP Filtering
When the firewall is enabled on a WAN or LAN interface, all incoming IP traffic is BLOCKED. However, some IP traffic can be ACCEPTED by setting up 'incoming' filters.
The Incoming IP Filtering Setup page contains a table of all currently defined Incoming IP filters and their details.
To create a new Incoming IP filter, click Add. The Add-Incoming IP Filter page will be displayed.
Filters must contain at least one condition.
A rule will only be effective if all the conditions specified in the filter
rule are satisfied.
To delete a rule from the Incoming IP Filtering Setup table click its Delete button.
