ProxyARP for Wifi - when I should enable it

Installing and Using OpenWrt
1

Hi,

I tried to find deeper information about ProxyARP feature that is disables for Wifi devices by default. The best information I found from Ubiquiti that it should be enabled in high Density networks to optimize broadcast requests. But when I have a high density network?

With Alexa, IOT devices, mobiles, etc. I have round about 25 active devices and one OpenWRT (ZyXEL NBG6817) router connecting everything...should I enable ProxyARP support??? Could it have side effects as it is disables by default also with other devices like Ubiqiuti?

Cheers,
Nils

I've always enabled it. ARP eats airtime and it having the AP respond might also extend battery for your battery powered devices
