#You can also check the proxy arp for a specific interface
show security nat proxy-arp interface <interface name>
>The output will show the interface name, the IP address that the proxy arp is configured for, and the number of ARP requests that have been handled by the proxy arp
>If the proxy arp is working as expected, you should see a non-zero value for the number of ARP requests
>It's important to note that proxy ARP is typically used in conjunction with NAT, so if the NAT is not working as expected, it's likely that the proxy ARP is not working as expected either
>It's also important to check if the proxy arp is enabled on the correct interfaces and that the interfaces are in the correct zone
>It's also good practice to check the arp table to confirm that the arp entries are being resolved correctly
>You can use the command show arp to check the arp table
