ASA - implicit deny issue

[CSCO12047997]

I am having issues with a new ASA deployment.

I have an inside interface connected and routing into my network (I can ping pretty much everything I need to).  The issue is the return traffic.  All return traffic seems to be being blocked despite the fact I have an ACL rule explicitly allowing it.

When I ran the packet tracer tool it told me my implicit deny rule was blocking the traffic but why would that be the case if I have a rule specifically allowing this traffic?

Since ACLs rules are read in order shouldn't this traffic never even reach the implicit deny?

Thanks.

Did this.  Made no difference.

I see no rules that would allow 10.20.0.13 -> 10.20.0.200 ICMP traffic whatsoever in your configuration that you provided.  The packet-tracer is working correctly.
