Proxy-arp on router thernet interface

[BicMac080]

Hello,

Is there somebody who could explain me under which conditions the proxy-arp can be disabled on the interface ethernet of a router ?

Thanks

There's no reason to have it turned on in the first place, so I'd turn it off unless you need it. If you don't think you need it, you probably don't need it. In fact, most security experts recommend turning it off.
