Firewall not connecting to Panorama

L1 Bithead

Hello I have new deployed Panorama and new PA-440 Firewall.

I setup Panorama with all basic settings like IP address/netmask, default GW, DNS, it has license assigned.

Next I generated AuthKey for the firewalls with validity for 10 days and without SN specified. 

 

PA-440 is in remote location and has a basic WAN setup and IPSec VPN to my datacenter where panorama is. 

It has a vlan interface setup in my internal zone and set as source for every service.

I am able to ping Panorama from the PA-440 so network over VPN is working.

When I setup Panorama IP with Auth Key on the firewall and add Firewall on panorama by the Serial Number I still see PA-440 in panorama as Disconnected.

I checked the DataCenter firewall where IPSec is terminated and I can''t see in logs any blocked traffic in between these two.

Port 3978 for Panorama  is enabled in security rules and I can see some ssl traffic is passing in Datacenter over this port.

Is there something else I forgott to setup or something else I need to check in order to be able to manage this Firewall by Panorama?

Thank you for reply and getting logs @AdamHP

 

The Error 5 is "SSL verification failure". Unless you configured mutual SSL authentication, only Panorama has to present a certificate: https://docs.paloaltonetworks.com/panorama/10-2/panorama-admin/set-up-panorama/set-up-authentication...

 

Would it be possible one more time to check the certificate on Panorama? The certificate is self signed, however could you confirm: valid to, issuer, subject,...?

 

Kind Regards

Hi Pavel,

It is issued to my panorama IP address.

Check under Monitor -> Session Browser under each firewall it flows through, even the source firewall.

Had the same problem and it turns out Panorama traffic won't match a catch all, it must specifically be application Panorama.

Thank you all for help, it turns out that on source firewall PA-440 I allow traffic for Panorama Application on its default port 3978, but in firewall monitor I found that the flow is recognized as ssl on port 3978 and this was blocked. 
I was thinking that once there is Panorama app it will be match and didn't check this, but I was wrong. 🙂
I had simmilar issue today on another firewall in Data Center where we had rule for WinRM (microsoft-remote-management), which was working fine before but now after some updates it is recognized as web-browsing on the WinRM port 5985.
So the solution is to not trust the Palo Alto application matching and always check the flows.

I have also PA-440 on 10.2 and Panorama on 10.2. And same issue, FW disconnecting. I think this is a bug with 10.2
