The configuration page is as shown below.
[Enable ARP Protection]: Select [Enable] to enable the ARP spoofing protection function.
[Static ARP List]: If the gateway of the LAN PC is not an interface IP address of the IAM gateway
device, the [Static ARP List] should be configured. Provided that, the gateway mode of the IAM
gateway device is Bridge mode; the gateway address of the LAN PC is the interface IP address of
its front-end router (or firewall), in this case, we have to add the IP/MAC address of the front-end
router to the [Static ARP List]. If the LAN PC has installed the Ingress Client, then it can get the
correct IP/MAC address of the gateway and bind with it; therefore, we can make sure that the
IP/MAC address of the gateway is correct.
[Broadcast Gateway MAC Address]: Indicates the frequency broadcasting the MAC address of the
gateway (the LAN interface of the IAM gateway device), in unit of second.
<Broadcast>: Click this button to manually and immediately broadcast the MAC address of the
device‟s LAN interface. When the ARP spoofing is eliminated, clicking this button can restore the
ARP table of the LAN PC swiftly.
Having completed configuring this page, you have to click the <OK> button to save the settings.
