It allows all icmp including ping's !!
Do "permit icmp any any ?" and you'll see the options,

Hi guys,
I hope this isn't too dumb a question, but...
Can someone confirm what this acl entry does?
ip access-list ext ping
permit (or deny) icmp any any <-----
In particular, does this allow all icmp message types or just echo-request
and echo-reply?
I've search the Doc Cd and the whole of cisco.com but couldn't find anything
definative.
I would think it would allow ( or deny) all icmp message types but, I'm
doing practice IE lab 2, task 10.8 - 10.10 and the solution seems to
indicate that it only permits message types echo-request and echo-reply.
Any feedback would be appreciated. Also, if someone knows of any links
which discusses in detail, please let me know.
TIA, Tim
