Tim,
The task states to limit the amount of ICMP traffic and not ping
traffic.

Subject: icmp filtering
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
