The device will answer incoming ARP requests for all non-

local IP addresses the device has an IP route to. It will then

behave as a router for such addresses even for devices that

have no proper routing configuration for this non-local

network. If the device has a dial-in PPP interface, ticking

this checkmark will allow the remote client to access the

entire network

• Check ARP Helps to avoid ARP spoofing attacks but may cause interop

problems
