Solved: Could not ping inside Host from Internet

man3mar3n · ‎12-21-2015

Hi,

I need to ping host 211.25.206.253 from Internet. The IP is a nat from a inside IP 10.200.200.5. I attached the config. I read through some of the same problem in the forum, but it just not working. Please help to isolate the problem.

In your configuration you have permitted ip any to the host on DMZ:

access-list ACL-OUT2IN extended permit ip any object OBJ-NET-DMZ-ASTERISK-TEST

With this configuration and icmp inspection in place you should be able to ping, but if it is not working then you can try couple of things:

>> Check if you can ping the host 10.200.200.5 from ASA.

>> Run packet-tracer and see how ASA is processing the traffic.

packet-tracer input outside icmp <anyip> 8 0 <public ip of host>

>> if there is no issue seen in packet-trace then try

#debug icmp trace

#term mon

and run the icmp, you should debugs on screen for icmp packets.

+ disable debugs: undebug all

Thanks,

R.S.
