Calico enhancements
- Calico v3.27.4 is out and here is why you should install or update your Calico instance:
Introducing Automatic SSL/TLS: securing and simplifying origin connectivity
During Birthday Week 2022, we pledged to provide our customers with the most secure connection possible from Cloudflare to their origin servers automatically. I’m thrilled to announce we will begin rolling this experience out to customers who have the SSL/TLS Recommender enabled on August 8, 2024. Following this, remaining Free and Pro customers can use this feature beginning September 16, 2024 with Business and Enterprise customers to follow.
Although it took longer than anticipated to roll out, our priority was to achieve an automatic configuration both transparently and without risking any site downtime. Taking this additional time allowed us to balance enhanced security with seamless site functionality, especially since origin server security configuration and capabilities are beyond Cloudflare's direct control. The new Automatic SSL/TLS setting will maximize and simplify the encryption modes Cloudflare uses to communicate with origin servers by using the SSL/TLS Recommender.
We first talked about this process in 2014: at that time, securing connections was hard to configure, prohibitively expensive, and required specialized knowledge to set up correctly. To help alleviate these pains, Cloudflare introduced Universal SSL, which allowed web properties to obtain a free SSL/TLS certificate to enhance the security of connections between browsers Continue reading
Celebrating one year of Project Cybersafe Schools
August 8, 2024, is the first anniversary of Project Cybersafe Schools, Cloudflare’s initiative to provide free security tools to small school districts in the United States.
Cloudflare announced Project Cybersafe Schools at the White House on August 8, 2023 as part of the Back to School Safely: K-12 Cybersecurity Summit hosted by First Lady Dr. Jill Biden. The White House highlighted Cloudflare’s commitment to provide free resources to small school districts in the United States. Project Cybersafe Schools supports eligible K-12 public school districts with a package of Zero Trust cybersecurity solutions – for free, and with no time limit. These tools help eligible school districts minimize their exposure to common cyber threats.
Cloudflare’s mission is to help build a better Internet. One way we do that is by supporting organizations that are particularly vulnerable to cyber threats and lack the resources to protect themselves through projects like Project Galileo, the Athenian Project, the Critical Infrastructure Defense Project, Project Safekeeping, and most recently, Project Secure Health.
Schools are vulnerable to cyber attacks
In Q2 2024, education ranked 4th on the list of most attacked industries. Between 2016 and 2022, there were 1,619 K-12 cyber incidents. Continue reading

Building Layer-3-Only EVPN Lab
A few weeks ago, Roman Dodin mentioned layer-3-only EVPNs: a layer-3 VPN design with no stretched VLANs in which EVPN is used to transport VRF IP prefixes.
The reality is a bit muddier (in the VXLAN world) as we still need transit VLANs and router MAC addresses; the best way to explore what’s going on behind the scenes is to build a simple lab.

The modern use of "cloud" arguably traces its origins to the cloud icon, omnipresent in network diagrams for decades. A cloud was used to represent the vast and intricate infrastructure components required to deliver network or Internet services without going into depth about the underlying complexities. At Cloudflare, we embody this principle by providing critical infrastructure solutions in a user-friendly and easy-to-use way. Our logo, featuring the cloud symbol, reflects our commitment to simplifying the complexities of Internet infrastructure for all our users.
This blog post provides an update about our infrastructure, focusing on our global backbone in 2024, and highlights its benefits for our customers, our competitive edge in the market, and the impact on our mission of helping build a better Internet. Since the time of our last backbone-related blog post in 2021, we have increased our backbone capacity (Tbps) by more than 500%, unlocking new use cases, as well as reliability and performance benefits for all our customers.
A snapshot of Cloudflare’s infrastructure
As of July 2024, Cloudflare has data centers in 330 cities across more than 120 countries, each running Cloudflare equipment and services. The goal of delivering Cloudflare products and services everywhere remains consistent, although Continue reading

Migrating a Data Center Fabric to VXLAN
Darko Petrovic made an excellent remark on one of my LinkedIn posts:
The majority of the networks running now in the Enterprise are on traditional VLANs, and the migration paths are limited. Really limited. How will a business transition from traditional to whatever is next?
The only sane choice I found so far in the data center environment (and I know it has been embraced by many organizations facing that conundrum) is to build a parallel fabric (preferably when the organization is doing a server refresh) and connect the new fabric with the old one with a layer-3 link (in the ideal world) or an MLAG link bundle.

Palo Alto Object and Policy Cleanup with pan-os-php
Hi all, welcome back to yet another Palo Alto Automation post. If you work with firewalls, you know that one of the most time-consuming tasks is decommissioning a single resource or an entire subnet from the firewall (aka removing all the references related to the resource). Let's imagine you have thousands of address objects and several hundred security policies. Now, suppose we decommissioned a server and our task is to remove any references we may have in the firewall. It could be an address object, a member in an address group, or a reference in a security policy. Removing this manually would take a lot of time, so in this blog post, let's look at a very simple way of cleaning this up using pan-os-php.
The Problem with the Manual Approach
Here is the problem with the manual approach. Let’s say we are trying to decommission the IP address 10.10.10.25. Let's say we have an address object created for this server, and it has been referenced in a few address groups and several security policies. If you try to remove the address object first, the firewall will complain because the object is being referenced elsewhere. So, you Continue reading

Review: Gowin 1U 2x25G (Alder Lake – N305)
Introduction
Last month, I took a good look at the Gowin R86S based on Jasper Lake (N6005) CPU [ref], which is a really neat little 10G (and, if you fiddle with it a little bit, 25G!) router that runs off of USB-C power and can be rack mounted if you print a bracket. Check out my findings in this [article].
David from Gowin reached out and asked me if I was willing to also take a look their Alder Lake (N305) CPU, which comes in a 19” rack mountable chassis, running off of 110V/220V AC mains power, but also with 2x25G ConnectX-4 network card. Why not! For critical readers: David sent me this machine, but made no attempt to influence this article.
Hardware Specs
There are a few differences between this 19” model and the compact mini-pc R86S. The most obvious difference is the form factor. The R86S is super compact, not inherently rack mountable, although I 3D printed a bracket for it. Looking inside, the motherboard is mostly obscured bya large cooling block with fins that are flush with the top plate. There are 5 copper ports in the front: 2x Intel i226-V (these Continue reading
Global Protect Authentication Cookies and Prevent Multiple MFA Prompts
In this blog post, let's look at a common scenario where users face two MFA prompts when trying to connect to Global Protect VPN. Typically, this happens because MFA has been set up for both the portal and the gateway.
When a user connects to GP, the user first logs into the portal and completes the MFA, then, they automatically attempt to connect to the gateway, which triggers another prompt. We'll look at how to prevent two MFA prompts using authentication cookies, so the user only needs to complete the MFA once.
Global Protect Cookie Authentication
Cookie authentication simplifies the authentication process for users because they will no longer be required to log in to both the portal and the gateway in succession or complete multiple MFAs to authenticate to each. This improves the user experience by minimizing the number of times the users enter credentials.
To keep things simple, when a user logs into Global Protect, we can configure it to generate a 'cookie.' This cookie allows the user to re-authenticate automatically without having to re-enter their credentials or go through MFA again. It's similar to how web browsers remember your login details for websites; once Continue reading
