MGMT routing issue

L2 Linker

Hello,

 

How can I get MGMT to ping to the LAN port?

Traffic can only take blue path.

There is no interconnection or routing between management module and dataplane (LAN on your diagram) inside Palo.

Packets from sourcing from management interface physically leave management interface to get to the destination.

Hi @young19918 ,

 

Using the command ping host <IP address> and you will automatically ping from your mgmt interface:

Hi @kiwi ,

Thanks for your reply.

 

I've tried this before, but had some problems ...... (as shown in the picture below)

These two red boxes show the source should be the same (mgmt), but one works and the other doesn't ......

And it can also ping the LAN port of the PA, why can't ping a server with port docking? (192.168.30.1)

Hello,

Is what you are attempting to ping in a different vlan or security zone? Could be the PAN blocking you?

In addition to what @OtakarKlier suggested, do you have ping enabled on the Data interface? Every interface has a Management Profile which lists the services that are allowed to run on that interface (except the Management interface which is handled a little bit differently). The interface Management Profile can be found under: Network-Interfaces->[interface_config]->Advanced->Other Info-Management Profile.

 

The Management Profiles define which services (ping, HTTP/HTTPS, SSH, etc.) can run on an interface and are configured from: Network->Network Profiles->Interface Mgmt

Is 10.2.100.54 your firewall management interface or have you enabled Interface Management profile on dataplane interface with IP 10.2.100.54?

 

ping host 1.1.1.1 (ping request goes out from mgmt interface)

ping source x.x.x.x host 1.1.1.1 (ping goes out from dataplane interface with IP x.x.x.x)

Hi @Raido_Rattameister ,

Thanks for your reply.

 

Now I know the difference between these two.
But I still have a question, if can ping to 192.168.30.254, why can't ping to 192.168.30.1 (architecture diagram below)

Well command "ping host 192.168.30.1" sends ping out from management interface.

Something needs to route from 10.2.100.x network to 192.168.30.x network.

 

Packet don't jump from management plane to dataplane inside firewall. Those packets will actually exit from management interface and need to be routed to different subnet to reach 192.168.30.1

Hi @Raido_Rattameister ,

Thanks for your reply.

 

It looks like there should be

Do you have any dataplane interface with 10.2.100.x IP.

What is default gateway IP configured on mgmt interface?

Hi @Raido_Rattameister ,

In "Monitor > Traffic" you should see traffic from 10.2.100.54 to 192.168.30.1

If you don't then check that you have overridden interzone-default rule at the bottom of the ruleset and chosen "Log at session end".

If you see sessions but no return packets then OS firewall is blocking incoming ping.

Hi @Raido_Rattameister ,

Thanks for your reply.

Yes,I have chosen "Log at session end".

But I can't see any session...

Is management port connected somehow to ethernet1/1 (either directly or through switch)?

What is output of "traceroute host 192.168.30.1"?

Hi @Raido_Rattameister ,

 

It seems that MGMT is first sent to the outside of the core and has no way to switch itself in the PA.
