PAN-DB URL Version Remains 0000.00.00.000

jlieberman — Thu, 24 Sep 2020 18:05:35 GMT

The firewall is running 9.1.4 (5250). The mgmt interface does not have general internet access so service routes have been configured for the following to use the external interface (internet connected):

DNS

EDL

NTP

Palo Alto Networks Services

URL Updates

Policy is created to allow outbound traffic to the internet sourced from the external IP (NAT in place as well).

NTP is working

NTP state:
NTP synched to 1.us.pool.ntp.org
NTP server: 0.us.pool.ntp.org
status: available
reachable: yes
authentication-type: none
NTP server: 1.us.pool.ntp.org
status: synched
reachable: yes
authentication-type: none

Support check is good

Hi @jlieberman ,

You need to download the initial seed file for the PAN-DB.I believe you are missing the second step from this document

https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClIdCAK

When URL filtering is enabled firewall will evaluate the URL that is passing through it, as you can imagine the are so many urls that FW cannot store information for all of them. That is why it will contact Palo Alto cloud and ask for evaluation, when reply is received the firewall will cache it and if it needs to check the category for the same url it will use the cached value instead of asking the cloud again (saving time and resources). The initial seed file is basically pre-build cache file with most visited address for given region. So in order to enable the engine it needs to have this initial cache file. As mentioned the seed file contains of trending address for given region, and Palo Alto is updating this information periodically, that is why fw will periodically download newer version of this file.

It is recommended to select the relevant region for which your firewall is located, this will ensure that more of the urls that you need to evaluate are already in the cache

@aleksandar.astardzhiev Thank you for the prompt reply but that seed file is a thing of the past and no longer used in PANOS 9.0 and later.

@aleksandar.astardzhiev as can be seen at https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000PNx4CAG

Additional Information
The below commands do not work on OS 9.0.x but will work on prior OS versions and will fix the Pan-DB 0000.00.00.000 issue:

> request url-filtering download paloaltonetworks region <region_name>
> request url-filtering download status vendor paloaltonetworks

Thanks @jlieberman ,

I was not aware of this change, I will have it in mind.

The only other reason I have experience is if the firewall is in active-passive HA and the secondary member is not able to connect to the cloud via the service route as it doesn't have running routing engine.

Have you tried to confirm to run some captures to confirm bi-directional connectivity to the cloud?

First check with capture that you see DNS requests and replies. Based on the DNS reply run capture with returned cloud ip and check what traffic is generated. Most probably it will be SSL but at least you can confirm that you have basic TCP connectivity.

I've no idea why, but it seems that my URL-filtering DB started working today.
