ASA ACL Blocking

EngineeringAir
Level 1
Level 1

‎09-28-2021 06:56 AM

Hi Cisco Community,

 

I am hoping someone can help me out.  Myself and another Engineer have run multiple tests on the ASA and have come up empty.

 

We have an ACL that allows traffic between two servers on two different networks.  When we attempt to pass traffic between the two the ASA shows deny by access group "Access Group X" in the live log file.

 

The Packet tracer done on the ASA CLI shows allow. Either this is a bug or an issue with the configuration, I cant seem to spot it.

 

When we look at the ACL rules it does not show any blocks between the two but allowed. 

 

Thanks,

 

E

Probably you are running packet tracer incorrectly as you do see it getting blocked in the syslogs.

 

We can help but I will need more details in terms of IPs and interfaces, or the packet tracer output, you can chose to put fake IPs as long as you can correlate them back and forth while we try to figure this out.

 

Regards,

Chakshu

Hi Shakshu,

 

Please forgive me if I miss anything.  Thank you for your help.  Please see below a description of the interfaces and the Packet tracer I am running. If you have any suggestions to try, please let me know.

"packet-tracer input Server_DMZ icmp 10.10.10.1 8 0 84.1.1.1 detailed"

 

Shouldn't you be running "packet-tracer input Inside icmp 10.10.10.1 8 0 84.1.1.1 detailed" instead?

You need to have the source interface mentioned while running the packet tracer.

Syntax:

packet-tracer input $source-interface $traffic-type $src_address $src_proto $src_proto_options $dest_address

Are

Interface Inside 10.10.10.1

Interface Server_DMZ 84.1.1.1

the interface IPs? Because you are actually supposed to put the src and dst IPs as packet tracer will then show "through" the box trace output.

 

One more thing I would check would be routing as packet ingressed from inside is going towards inside, which should not be the case as per your requirement.

Hi Chakshu,

 

Those are not the interfaces, they are just the two endpoints. 

 

Is there a specific route you would like me to look at?  

 

The Static Routes we have should route between the two networks.

 

Thanks,

Is it that traffic is passing successfully but you are seeing drop logs or is the traffic actually being dropped / not allowed?  Could you post the actual log you are seeing (screenshot).  Post the full output of your packet-tracer including the command you are running.

Also, a full running configuration (change any public IPs and remove usernames and passwords.

Hi Marius,

 

I replied with the output of the packet tracer.  I will upload the full running configuration once I sanitize it.  

 

Thank you,
