router as well as through the router. Zones are defines as one or more interfaces that
serve as source or destination interfaces used to forward traffic.

on page 8).
2. Click on Network, click on Firewall, and click on the General Settings tab.
3. Review the settings below. When complete, click Apply to save and commit your
changes.
General Settings
 Drop invalid packets – By default, this function is disabled and will allow the router
to respond to any packets received on any interface whether the packet is invalid or
not. Enabling this function will set the router to drop all packets found to be invalid
without any response to the sender which can increase security and prevent denial
of service (DoS) attacks.
 Input – This setting defines the global action of how to handle traffic destined for
the router inbound on an interface in a specific zone.
 Output - This setting defines the global action of how to handle traffic originating
from the router outbound on an interface in a specific zone.

between interfaces in a specific zone.
