MAC / IP / Port filtering
The MAC/IP/Port filter feature allows you apply a policy to the traffic that passes through the router, both inbound and outbound, so
that network access can be controlled. When the filter is enabled with a default rule of “Accepted”, all connections will be allowed
except those listed in the “Current MAC / IP / Port filtering rules in effect” list. Conversely, when the default rule is set to “Dropped”,
all connections are denied except for those listed in the filtering rules list.
Figure 66 - MAC / IP / Port filtering
Note: When enabling MAC / IP / Port filtering and setting the default rule to “Dropped”, you should ensure that you have
first added a filtering rule which allows at least one known MAC/IP to access the router, otherwise you will not be able to
access the user interface of the router without resetting the router to factory default settings.
Creating a MAC / IP / Port filtering rule
To create a filtering rule:
1. Click the MAC / IP / Port filtering toggle key to switch it to the ON position.
2. Using the Default rule (inbound/forward) drop down list, select the default action for the router to take when traffic reaches
it. By default, this is configured to Accepted. If you change this to Dropped, you should first configure a filter rule that
allows at least one device access to the router, otherwise you will effectively be locked out of the router.
3. Click the Save button to confirm the default rule.
4. In the Current MAC / IP / Port filtering rules in system section, click the +Add button.
