In which file is the proxy ARP configuration stored?

• A. $FWDIR/state/proxy_arp.conf on the management server
• B. $FWDIR/conf/local.arp on the management server
• C. $FWDIR/state/_tmp/proxy.arp on the security gateway
• D. $FWDIR/conf/local.arp on the gateway

Answer: (D)

The configuration for proxy ARP is primarily stored in the local.arp file located in the configuration directory of the security gateway. This file plays a critical role in defining how the gateway responds to ARP requests for IP addresses that are not directly assigned to local interfaces. By managing this configuration in local.arp, administrators can effectively control how the security gateway interacts with ARP requests, allowing for proper network communications in scenarios where proxy ARP is necessary. The local.arp file ensures that the rules for proxy ARP can be customized per gateway, which is essential for maintaining network integrity and security. This file contains mappings that the gateway uses to forward requests to correct interfaces, a vital function in environments where IP addresses are shared or stretched across multiple networks. Understanding the significance of the local.arp file highlights the importance of proper ARP configuration in network security practices, as it directly influences the effectiveness of the security gateway in managing traffic and maintaining communication with devices across network boundaries.
