Panorama and Firewall Communication

[Ramakrishnan]

Dear All, 

I have Panorama hosted in one of the location [where geo graphically separated] abd my Managed firewall are located across the globe. Due to Embargoed few countries I don't have  option to establish S2S VPN or any other over lay. So I have left with option plain internet. 

Question1: What are the communication I could expect from Panorama inbound and Outbound from/to Managed firewalls. 

Question 2: Is there no inbound inbound connection from Managed firewalls to Panorama?

Question 3: From my Panorama hosted sites If do address translation [ NAT] Panorama Private IP address to Public IP address, then  I shall register managed firewalls with Panorama hosted location Public IP address. 

Regards,

Ram

Hi @Ramakrishnan ,

Communication between Panorama and managed device is always initiated by the NGFW.  The primary communication will be  over tcp/3978.  https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/firewall-administration/reference-port-nu...

You need to use the public IP address of Panorama so the NGFW can initially connect.  In addition to the NAT, the public IP address for Panorama should be configured under Panorama > Setup > Interfaces > Management > Public IP Address.

I would configure the NGFW to use the public interface for Panorama and Panorama Log Forwarding under Device > Setup > Services > Service Route Configuration so there is less chance any NGFW changes would break the connection.  And you should enable automated commit recovery.

Thanks,

Tom
