OT:NAT Issue

Dear Experts,

I have been stuck in this scenario and not able to understand what is wrong.
I would truly appreciate your help..
Topology is R1--ASA1--R2
Subnet R1--ASA1 (136.1.121.0/24) (INSIDE)
Subnet ASA1-R2 (136.1.122.0/24) (OUTSIDE)

I have been trying to nat the outside network (between ASA1/R2) to the
inside interface of ASA1 (PAT). The configuration is shown:
nat (outside) 1 136.1.122.0 255.255.255.0 outside
global (inside) 1 interface
access-list OUT_IN permit ip any any
access-group OUT_IN interface outside

When pinging from R2 to R1 as far as I understand, R2's address
(!36.1.122.2) will be mapped to (136.1.121.12) ASA's inside interface, and
then R1 will respond to this and then the opposite mapping will take place
from ASA's inside interface to R2.

show xlate (does indeed show translation happening)
PAT Global 136.1.121.12(33122) Local 136.1.122.2 ICMP id 33

When doing a capture on inside interface this is what I see however on the
inside interface I should see the translated address of R2(ASA inside)
however it doesn't show
