Terry,

 

I believe there may have been a bug in the 12.4(22)T code when I wrote that
lab.  For some reason when I inspected ICMP both ways it would drop the ICMP
packets with policy match failures on the inbound zone pair.  Since
Upgrading to 12.4(24)T I no longer see that same problem so I may switch the
solution in some of the earlier labs.  But regardless the most important
thing is that your solution works.  Don't worry so much about matching the
solution exactly, it matters most that you are meeting the requirements.  I
hope this helps to answer your question.

 

Regards,

I was curious as to why the solution for this section calls out special
treatment for the icmp packets. Aren't these packets already covered by
other lines in the configuration? It seems to work fine for me without the
icmp specific class and policy configuration.
