I'm labbing with 2 ASAs and having problem pinging from "host" to "ISP-1" and "ISP-2"
Failover on the ASAs. I can reach ISPs from ASA itself, but not from the host. icmp are allowed on the ASAs inbound and outbound.
------------------------------------------------------------------------------
access-list OUTBOUND_TRAFFIC extended permit icmp any any echo
access-list OUTBOUND_TRAFFIC extended permit icmp any any echo-reply
access-list INBOUND_TRAFFIC extended permit icmp any any echo
access-list INBOUND_TRAFFIC extended permit icmp any any echo-reply
access-list INBOUND_TRAFFIC extended permit icmp any any unreachable
access-list INBOUND_TRAFFIC extended permit icmp any any time-exceeded
------------------------------------------------------------------------------
on the Host node, I have its default-gateway as ASA's inside interface.
this is debug ip packet detail on the Host node:

when I do packet tracer on the ASA, everything shows ALLOWED:
packet-tracer input inside icmp 1.0.0.5 8 0 10.0.0.1
1.0.0.5 (host)
10.0.0.1 (ISP-1)
I'm using VIRL for labbing.

Have you enabled ICMP-inspection?
fixup protocol icmp
With that you don't need the ACEs for the return-traffic. But that's probably not the problem.
On the ISP-router, you can do a "debup ip icmp" to see if the pings reach the ISP-router.

Sorry forgot to mention "inspect icmp" is on
i haven't tried debug on the ISP side.
