Configure the following lines in global configuration mode
access-list 115 deny icmp any any echo
access-list 115 deny icmp any any echo-reply
access-list 115 permit ip any any
Then apply the following commands on your external interface at interface configuration level:
ip access-group 115 in
ip access-group 115 out
Here is a captor from a router in which I did the configuration:
acc-r12-SOHO91-2>en
acc-r12-SOHO91-#conf t
Enter configuration commands, one per line. End with CNTL/Z.
acc-r12-SOHO91-2(config)#access-list 115 deny icmp any any echo
acc-r12-SOHO91-2(config)#access-list 115 deny icmp any any echo-reply
acc-r12-SOHO91-2(config)#access-list 115 permit ip any any
acc-r12-SOHO91-2(config)#int ethernet1
acc-r12-SOHO91-2(config-if)#ip access-group 115 in
acc-r12-SOHO91-2(config-if)#ip access-group 115 out
acc-r12-SOHO91-2(config-if)#exit
acc-r12-SOHO91-2(config)#exit
