Published ARP Objects
NetDefendOS supports publishing IP addresses on a particular interface, optionally along with a specific MAC address instead of the interfaces MAC address. NetDefendOS will then send out these as ARP replies for any ARP requests received on the interface related to the published IP addresses.
This can done for a number of reasons:
• To give the impression that an interface in NetDefendOS has more than one IP address.
This is useful if there are several separate IP spans on a single LAN. The hosts on each IP span may then use a gateway in their own span when these gateway addresses are published on the corresponding NetDefendOS interface.
• Another use is publishing multiple addresses on an external interface, enabling NetDefendOS to statically address translate traffic to these addresses and send it onwards to internal servers with private IP addresses.
• A less common purpose is to aid nearby network equipment responding to ARP in an incorrect manner.
