TCP Ports and FQDNs Required for Cortex Data Lake
List of FQDNs and ports that you must allow to ensure connectivity to the Cortex Data Lake.
If you are using a Palo Alto Networks firewall to secure traffic between Panorama, the firewalls, and the Cortex Data Lake, use the App-ID “paloalto-logging-service” in a Security policy rule to allow Panorama and the firewalls to connect to the Cortex Data Lake and forward logs on TCP 444 and 3978, the default ports for the application.
If you are using another vendor’s firewall, use the following table to identify the fully qualified domain names (FQDNs) and ports to which you must allow traffic to ensure that Panorama and the firewalls can successfully connect to the Cortex Data Lake.
|FQDNs and Ports used||Description|
Use the FQDNs that match the Cortex Data Lake region to which your firewalls and Panorama connect:
The firewalls use the FQDN on port 3978 and 444 to forward logs to the Cortex Data Lake.
Panorama uses the FQDNs on port 444 to connect to the Cortex Data Lake for other log query and validity checks.
Panorama needs to access these FQDNs for the initial setup and one-time password, and for ongoing certificate revocation checks.
For OCSP, you must also allow the firewallsto access ocsp.paloaltonetworks.com on port 80.
