Cannot ping FW from CentOS connected VM

Dear experts;

 

I have the following setup in Azure:

 

CentOS-1 --------(fwVNET/Trust)-----FW----------(fwVNET/Untrust)-----CentOS-Untrust

 

 

But I cannot ping FW interface even with all Mgmgt profiles and addresses configured (which are in same subnet obviously). All NSG's in Azure allow ICMP, and even SSH is not allowed.

 

Can anyone help?

Re: Cannot ping FW from CentOS connected VM

is ARP resolving on the firewall ? Have you verified there's no security policy blocking the pings (app ping instead of icmp or implied intrazone policy at the end). Can you doublecheck the mgmt profiles have ping checked and are assigned to the interfaces

Yes profiles have ping checked, and ARP is not resolving....which means a Layer 2 disconnet, but why?

Re: Cannot ping FW from CentOS connected VM

Should i allow ARP (via Ethertype)in my custom Interface profiles attached to interfaces?

What exactly does "done by palo alto support" mean?

 

Can you please provide a case number?

It means:

 

  1. Whenever yuou deploy a VM in Azure, never configure a Static IP inside of Guest OS, it is alwys via DHCP even if Static IP in Azure is selected.
  2. Azure has a completely different routing architecture than other Hypervisors.

cheers.
