 The file that contains the host address to be published, the MAC address that needs to be associated with the IP address, and the unique IP of the interface that responds to ARP request is $FWDIR/conf/local.arp. Local.arp is a configuration file that defines static ARP entries for hosts behind NAT devices. This file allows the Security Gateway to respond to ARP requests for NATed hosts with the correct MAC address, and to publish the NATed IP address instead of the real IP address. The other files are either not related or not valid.
