Two have a real "broadcast firewall" you should avoid proxy arp. Figure out, you want to get the hosts in a segment and ping to the broadcast address. In a normal routed segment without proxy-arp you only the the station answering, which are in the segment. Turning on proxy arp you also get answers from machines from other connected lans... I'd avoid that !
