Push to Devices from Panorama is not working when we make changes in the objects tab of any device groups belong to the firewalls managed by panorama. in other words, after making changes in the objects tab , we are able to commit to panorama but couldn't push it to the devices as commit is not triggered to the firewalls from panorama. Could you share your thoughts ? ,

Scenario : In an organization, a client machine doesn't know IP address of example.com. So it sends DNS query to its local DNS server. Even the local DNS server doesn't know about example.com. Hence, the local DNS server sends DNS query to DNS forwarder. DNS forwarder too doesn't have information about example.com. However , DNS forwarder is able to do external DNS lookup. Hence, It contacts root DNS server at first. secondly , It contacts TLD server and later Name server of example.com to get the IP address. I hope this is how DNS query works for external websites. Please correct me if I am wrong Question 1: I would like to know if IP address of example.com and IP address of its name server will be same or different. Question 2 : I would also like to know When DNS forwarder contacts name server of example.com asking for IP address of example.com, it will send normal DNS query as how client machine has sent DNS query for example.com to its local DNS server or it will be different

Seems we experience commit failure incase we want to redistribute null route if we create in this way. It works if we create a null route using the following document and redistribute it Palo Alto Networks Support for Null Routes https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000Clh9CAC#:~:text=Create%20an%20unnumbered%20dummy%20tunnel,option%20selected%20as%20%22none%22.

They updated me like there may be common license for our account and it could be the reason why it shows like that. Do you have any comments on it ?

We already have n number of Palo Alto firewalls and those are licensed. recently we purchased two new firewalls. Just wanted to activate license for those two new firewalls remotely. Registered these devices under Palo Alto support portal and activated license. License expiration date matches with our existing firewalls expiration date( in another few months going to expire) Since these two are new firewalls expiration date should be long and needs to be different. May I know why license expiration date is exactly matching ?

I would like to know what is the latest app and threat version after 8671-7826. When I do dynamic updates , It doesn't show any new version after 8671-7826. It seems Palo alto didn't release any new version last week. Could you help me make sure it ?

I would like to know advantage and disadvantage of implementing Vsys. in an environment , we are able to configure our firewalls with vsys or without vsys. Would also like to know whether configuring vsys will make firewall more secure or not ?

What privileges required by service account used by palo alto firewall in LDAP server profile to fetch group information from LDAP server for group mapping? Do we need admin privilege ? or is it enough that we need service account only to be a member of the following groups Event Log Reader Distributed COM Users Server Operators

I would like to know when to use Include or Exclude Subnetworks for User Mapping. in other words I would like to know whether it is used when we use agentless user id or external user id agent or in both cases?
