pix 525 routing question

my client got a pix 525-ur with two interface card . now i got a icmp ping problem with this pix device when i made some test. the follow is the test environment

PC1 ---- (inside) PIX (outside) --- PC2

10.47.240.22 10.47.240.254 10.47.253.253 10.47.253.254

PC1 directly connect the inside interface and ping the inteface normally, same to the PC2. the pc's default gw had also set to the pix interface address they direct connected

but when pc2 ping the inside interface , i got time out

and i debug packet outside saw that only one direction packet flow from pc2 to inside interface , but no packet from inside interface flow to pc2 , when pc2 ping pc1, debug packet outside got the same.

and i use pc1 to ping the pc2 ,i can saw the both direction packet flow between pc1 to pc2 when i debug packet outside , but the ping is still time out. the same to pc1 ping the outside interface

the follow is the pix configuration
