</strong></span>
*Proxy ARP can be used if you need {$g['product_name']} to send ARP replies on an interface for other IP addresses than its own (e.g. for 1:1, advanced outbound or server NAT). It is not necessary on the WAN interface if you have a subnet routed to you or if you use PPPoE/PPTP, and it only works on the WAN interface if it's configured with a static IP address or DHCP.</p>
<br>
*CARP can be a great replacement for proxyarp.
