Hi there,
From the configuration, i could see that next of the ASA is 10.153.66.2 and 10.153.67.2. Please check if icmp is allowed on your edge router 10.227.79.129. Also check if it is reachable from your next hop 10.153.66.2 ISP.
there is no icmp permit or deny configured on ASA that means it is allowed bydefault. So no issue.
Regards,
Akshay Rastogi
