![]() ![]() Since problems persisted after reboot I decided to reinstall Wireshark with all the same options. While you can use any internal interface for this purpose, Palo Alto recommends using a Loopback interface, since that type of interface with never be considered "down" and there is very little risk of the interface being removed or made obsolete by changes in the overall network design.Recently, after prompt initiated update, the Wireshark could no longer detect my ethernet interfaces, leaving only USBs on the list. What we should do, is use an internal interface as the source interface to download Dynamic Updates. ![]() One could think that using the internet-facing interface to download the Dynamic Updates would be feasible, but from what I have found, Palo Alto's documentation recommends not doing that, for security reasons. In this lab, we are going to change the source interfaces used to connect to the Palo Alto cloud services and confirm that we are receiving Dynamic Updates via the newly configured source interface. This is called configuring different Service Routes. Introducing Service Route Configurationįortunately for us, we can make the firewall use a different interface than the Management Port as the source interface for Dynamic Updates, or other features like the ones mentioned earlier. There could also be various cases where you want the firewall to communicate to certain services using different source interfaces, depending on your network design, security zone structure, server network structure, etc. In a real-world production network, having internet access from a dedicated management network isn't always guaranteed, and in those cases, you will have to configure some extra steps to get Dynamic Updates working, unless you want to manually have to upload updates to the firewall. You can also see that the firewall is having trouble establishing a connection to the Palo Alto cloud services. Basically, it doesn't have a proper URL Filtering function, yet. But because my firewall has never received these updates via its Management Port, the version is 0000.00.00.000, as shown on the image below. In the General Information section on the main Dashboard of the firewall, you can for example see which version of URL Filtering is currently installed. However, in my last article, I set up a virtual Palo Alto firewall in VMware, which had its Management Port connected only to a management PC, which means the firewall would be unable to properly use and maintain some of its components, for example, downloading updates to many of its features included in Dynamic Updates. This feature is called Dynamic Updates in the Palo Alto world.īy default, to connect to the Palo Alto cloud services which offer these updates, the firewall will attempt to reach the internet using the Management Port, and the same is true for a whole other bunch of operational features of the firewall, like those mentioned above. ![]() This includes communicating with user catalogs, sending emails with reports, sending logs to external servers, integrating with RADIUS/TACACS server, and downloading various updates to its components.įor example, for a Palo Alto firewall to receive updates to the subscription services like URL Filtering, Application database, Threat Prevention, and more, it needs to connect to a cloud service on the internet. While traffic arriving at a firewall is usually sent there to be inspected, a firewall has a bunch of different jobs of its own it has to take care of to properly function as a next-generation firewall. ![]()
