ARP issue, I see same IP on all interfaces

Can someone suggest it to me, when i ping my internal host which should be only on eth1 as per Keith barker cbt lab, i see it coming in arp on all interfaces of my firewall eth0,1,2.

What is your source and destination IP? What interface does your source and destination hosts come from/go to?
