10.97.37.22 24.234.0.1 24.234.0.100 192.168.2.100 192.168.2.101
I could not able to ping from PC to R1 router interface F0/0 (10.97.37.222) and I can able to ping F0/1 (24.234.0.1) from my PC.
From firewall I can able to reach this network 10.97.37.0/24 .Please let me know is there any additional command needs to be add in the firewall.

Hi,
On the firewall you seem to have a dynamic PAT from inside to outside. Hence, you will not be able to initiate connections from outside to inside unless you have an ACL to allow that traffic and a Static nat or Nat exemption.
I would suggest you to add the nat exemption for traffic from the PC to R1 and an access-list on the outside interface to allow traffioc from R1 to PC. The nat exemption would be of the form below:
access-list NONAT permit ip host 192.168.2.101 host 10.97.37.22
nat (inside) 0 access-list NONAT
Ensure to allow the traffic from R1 to the PC using an access-list on the outside interface.
Let me know how it goes!!
Thanks and Regards,
Prapanch
