Hi Ravi , Could you share tcpdump on P3 as well ( sudo tcpdump -n -e -i "P3 tab-interface" )
IMO , the possible reasons would be [1] port-security on SF port may block the packet , since it destined to different ip address. [2] The SF program may alter the IP Header (Destination field ) Flow rules are looks okay , and it shows packets are dropped in between p2 and p3 .
