Unable to Ping to Layer 3 interface

L0 Member

Hi , I have a Palo Alto 4020 . I have configured one of the interfaces as Layer 3 and also allowed Ping and telent on this interface . The IP given to this Layer 3 interface is and its default gateway is the VLAN interface Even when I connect a Laptop directly to the interface by giving the Laptop an IP of I am unable to ping the Layer interface. I also dont see any Traffic hitting the firewall when viewing the monitor TAB .

Do you have a deny all rule towards to bottom of your rule set?

Basically this would be a rule that denys all traffic to any zones. The primary purpose of this rule is typically to log even the traffic that is being denied. Having this "deny all" rule also blocks intra zone traffic that is normally allowed by default.

By "intra zone" traffic, I mean traffic from zone A to zone A, traffic from zone B to zone B, etc....

The traffic that you are describing from the PC to the interface would be "intra zone traffic".

Also verify that your interface managment profile includes the IP of the pc in the "permitted ip addresses".....if you have "permitted ip addresses".

thank you,


Stephen ,

I have done all the thinngs you have asked for and the problem remains unresolved . Can you please help think of other alternatives / solutions



can you call into support when you have remote access? We will be able to isolate this issue rather quickly if we are able to troubleshoot live.

I also encoutered exactly the same problem and I am using Palo Alto 500, OS version 3.1.6.

Policy already allowed both direction on the same zone. Ping to L3 interface at palo alto request time out.

Any way out?


Hi Edy,

Have you created an Interface Management Profile that allows Ping and configured it on the L3 interface?



Hi Kelly,

Thank you very much for the advice and it solved my problem.

I did not aware that management interface need to be created in order to be use.

I actually have the exact same problem (using 3.1.6), however what I found is that ping does work to a regular Layer 3 interface, it does not work on any of my  logical interfaces (sub-interface). I do have an interface management profile for 'ping only' applied to all regular and logical Layer 3 interfaces.

if you are still having an issue with pinging the logical interfaces please create a support case and we'll set up a remote session to further debug.
