Problem
You cannot ping anything on the outside of the Cisco Asa firewall
Solution
From the CLI, create a class map and assign to a policy
ASA(config)# class-map icmp-class
ASA(config-cmap)# match default-inspection-traffic
ASA(config-cmap)# exit
ASA(config)# policy-map icmp_policy
ASA(config-pmap)# class icmp-class
ASA(config-pmap-c)# inspect icmp
ASA(config-pmap-c)# exit
Assign the policy to the outside interface
ASA(config)# service-policy icmp_policy interface outside
Tested Platform
