Using the Configuration Menu (continued)
Advanced > Firewall
Firewall Rules is an advanced feature used to deny or allow traffic from passing
through the DI-524. It works in the same way as IP Filters with additional settings.
You can create more detailed access rules for the DI-524. When virtual services are
created and enabled, it will also display in Firewall Rules. Firewall Rules contain all
network firewall rules pertaining to IP (Internet Protocol).
In the Firewall Rules List at the bottom of the screen, the priorities of the rules are
from top (highest priority) to bottom (lowest priority.)

The DI-524 MAC Address filtering rules have precedence over the Firewall Rules.
