arp problem in pinging host

I have pc hostA with connected to pc R1 with eth0: and eth1: via crosscable when i ping from hosta to R1 request packet goes to R1 but R1 generates packets with srcip= and destination ip of R1's eth1= and hosta unable to receive reply packet from R1. But if i ping from R1 to hosta packet always goes to hosta and receives reply at R1. What can be the reason is that arp cache problem or what else?
When i send ping packet to R1 from hostA, the arp analysis on my both Linux machines shows that when i did arp -a on hosta and found output that
R1( at <incomplete> on eth0
and on R1 nothing is displayed.
When i send ping packet to hostA from R1, the arp analysis on my both Linux machines shows that when i did arp -a on
R1 and found output that
Address HWtype HWaddress Flags Mask Iface
hosta ether 00:08:F1:43:62:91 C eth1
and on hosta
Address HWtype HWaddress Flags Mask Iface
R1 ether 00:08:F1:43:61:C1 C eth0

whats wrong in hosta linux machine?

I don't think that arp is where your problem is. My guess is that you have some routing issues, probably on R1. Could you post the result of route -n on each computer?
