Fortinet has a misstep in its IPv6 settings: NAT66 is enabled by default for every policy. Not only does this make no technical sense and go against established best practices, but in my view, there’s an even bigger issue at play here: Given the widespread…
I had a use case where I wanted to use the SSL Inbound Inspection on a Palo, but with a different X.509 certificate than the one on the server itself. That is: the backend server has its self-signed (or internal PKI-signed) certificate along with its…
Did you know that you can easily decrypt TLS (mostly HTTPS) traffic with Wireshark? Well, only if you have the keys. 😉 This really is a game-changer if you’re stuck with troubleshooting encrypted data. Let’s do an example: TL;DR: You can decrypt TLS traffic with…
After years of customers confusing Fortinet with Fortnite, the two companies finally decided to lean into the chaos. The result: FortiNite — a joint innovation designed to deliver “next‑gen latency acceleration” for Fortnite players worldwide, a groundbreaking collaboration with Epic… Source link Author: legendary Johannes…
You never stop learning. One topic that hadn’t crossed my path in the past decade is: Multicast. Whew. Alongside all the technical literature, online presentations, and various blog posts, I decided to approach it the classic way – through packet captures. 😉 So here’s a…
A rare use case on a Palo (at least from my point of view): Multicast Routing. And it can become as complex as you want. Fortunately, the basics are relatively easy to configure, at least if you have a rough understanding of multicast and routing…
The other day, I was troubleshooting some network-related stuff, using the built-in Packet Capture on a Palo Alto Networks firewall. And while it did the job at a first glance, I stumbled upon some packets that were simply not correct, read: were not present on…
I had a hard time figuring out how to configure OSPFv3 authentication on a Palo Alto Networks NGFW due to its different configuration formats compared to a Cisco router. TL;DR: The SPI must be set in hexadecimal, while the actual key (40 chars, hexadecimal) must…
