All Inside Host Can't Ping ASA Inside Interface IP Address

am. — Fri, 01 May 2020 14:44:02 GMT

Hi All,

I have some probleme with our connction.

Early last week, our monitoring server in the inside zone could not reach the ASA device.

The server also cannot ping the IP interface inside and vice versa.

HW: ASA5585-SSP-10
SW: v9.8(2)38

Topology:

[Server] (10.40.83.180) <--------> (10.40.83.1) [ACI] (10.30.10.6) <--------> (inside: 10.30.10.1) [ASA]

(Default Route to ASA) (Static Route to ACI)

This is the result of trace-packet from the IP Interface Inside to the Monitoring Server

SF-FW# packet-tracer input inside icmp 10.30.10.1 80 0 10.40.83.180

==========================================================

I have added the following command but it has no effect.

icmp unreachable rate-limit 1 burst-size 1
icmp permit any outside
icmp permit any echo outside
icmp permit any inside
icmp permit any echo inside

Hope someone will give an answer that can solve this problem because this week we have not been monitored ASA.

Thanks.

Packet-tracer is designed to show how traffic would pass THROUGH the ASA. It is not a tool that has any utility for traffic to of from the ASA itself.

Have you tried a packet capture to confirm that the traffic is reaching the ASA? Also, i would suggest examine the logs on the ASA, filtering for traffic from the monitoring server.

Check routing to make sure that 10.40.83.180 can reach 10.1.30.1 and that the ASA has a route back to 10.40.83.180
