When to configure Proxy ARP

As specified in Configuring Proxy ARP (CLI Procedure), Proxy ARP should be configured for the following scenarios:

When addresses defined in the static NAT and source NAT pool are in the same subnet as that of the ingress interface (Source NAT and Static NAT scenario)
When addresses in the original destination address entry in the destination NAT rules are in the same subnet as that of the ingress interface (Destination NAT scenario)
