interface arp reply-only

Dear All,

I am using v3.22 hotspot with External radius host.

my problem is if i kept local lan interface arp reply-only net is not comming to the clients. if i put interface arp enable then net is comming. At that time ip hotspot hosts address and toaddress are changing very frequently…

bcz it is not static entry. how to reslove it.

Thanks
