Advanced
At Firewall > Advanced, more advanced settings on firewall rules can be configured, providing extra
security enhancement against DHCP and ARP traffic traversing the available interfaces of the system.
Trust Interface: Each VAP interface can be checked individually to mark as trusted interfaces; security
enforcements on DHCP/ARP like DHCP snooping and ARP inspection will be carried out on non-trusted
interfaces.
DHCP Snooping: When enabled, DHCP packets will be validated against possible threats like DHCP
starvation attack; in addition, the trusted DHCP server (IP/MAC) can be specified to prevent rouge DHCP
server.
ARP Inspection: When enabled, ARP packets will be validated against ARP spoofing.
-
Proxy ARP option when enabled, AP will reply ARP requests on behalf of downlink stations. The
ARP table maintained by the AP will be used as a look up table upon receipt of ARP request from
AP uplink. Adversely, without Proxy ARP, ARP request is broadcasted down into the AP’s wireless
network causing network inefficiencies.
-
Force DHCP option when enabled, the AP only learns MAC/IP pair information through DHCP
packets. Since devices configured with static IP address does not send DHCP traffic, any clients
with static IP address will be blocked from internet access unless its MAC/IP pair is listed and
enabled on the Static Trust List.
-
Trust List Broadcast can be enabled to let other APs (with L2 firewall feature) learn the trusted
MAC/IP pairs to issue ARP requests.
-
Static Trust List can be used to add MAC or MAC/IP pairs of devices that are trusted to issue ARP
request. Other network nodes can still send their ARP requests; however, if their IP appears on
the static list (with different MAC), their ARP requests will be dropped to prevent eavesdropping.
RF Isolation (between RFs): Clients are isolated between RF Card A and RF Card B.
VAP Isolation (within RF): Clients on different VAPs on the same RF Card are isolated.

RF Isolation (between RFs) may be limited on selected AP models.

VAP Isolation (within RF) may be limited on selected AP model.
