Explanation
Proxy ARP is a feature that allows a gateway to respond to ARP requests on behalf of another IP address that is not on the same network segment. Proxy ARP is required for manual NAT rules when the NATed IP addresses are not routed to the gateway. By default, proxy ARP for manual NAT rules has to be configured manually by editing the local.arp file or using the CLISH commands on the gateway. However, since R80.10, there is an option to enable automatic proxy ARP configuration for manual NAT rules by modifying the files $CPDIR/tmp/.CPprofile.sh and $CPDIR/tmp/.CPprofile.csh on the gateway. fw ctl proxy is a command that displays the proxy ARP table on the gateway, but it does not configure proxy ARP. Translate Destination on Client Side is a NAT option that determines whether the destination IP address is translated before or after the routing decision. It does not affect proxy ARP.
