vSRX policy-based IPsec VPN over GRE (part 1/2)
During the implementation of using my own public IP space on my home server I ran into a weird issue of not being able to pass traffic between hosts on either side of the VPN. After investigation it seems to be a combination of factors by using GRE tunneling, a policy based…Using my own public IP space on a regular internet connection with a Juniper SRX
Recently I purchased new servers for my home lab (topic for more posts to follow when everything is fully done). I wanted to use these servers to run a number of workloads (mainly virtual machines) and I wanted to use the public IP space I recently got for that. Of course my…My favorite podcasts
After my last blog about reading books I received a lot of good recommendations from people to have a good list of books to read! I figured it would be good to share my list of favorite podcasts as well.Read a book!
At the start of this year I set myself a number of goals. One of them was to read at least 1 book a month. I tried to accomplish a number of things with that. The first was to get the amount of screen time down. This also means reading books on paper, which I actually prefer over…New beginnings!
After long consideration I decided to take on a new role back at Juniper Networks! Over the past few months I have thought a lot about what I want in the future and how I can get there. When I had a chat with an ex-colleague at Juniper, he told me that they were looking to set-up…Next Generation Global Connectivity
Technologies like SDWAN have fundamentally changed the way we think about WAN infrastructures for enterprise IT environments over the past few years. Global WAN offerings are no longer a necessity as pretty much ‘any’ connectivity will do. You are no longer bound to private (MPLS-based) connections/networks. Software and smarter routing mechanisms will fix all your […]Next Generation Global Connectivity

Over the past few months I’ve been working hard on my new start-up company PeakFactory, it’s going really well, but for this post I want to focus on the reason why I chose to leave the companies I used to work for. I thought this was relevant, as many people have asked me why, but also in general there is a lot of discussion how to advance your career in different directions.
Why leave a comfortable and good job at all?
Back in 2013 I was working in a very good position, where I had a lot of freedom in choosing the customers I’d like to work on and was involved in all technical aspects of a project (pre-sales, proof of concepts, implementation and support). Still I had this feeling that I wanted to explore more an different areas for a wider audience. Which is why I decided to start working for a networking vendor. My main reason for choosing a vendor is that I could leverage my experience in the technology and apply it for a wider audience (maybe even worldwide)
Why work for Cisco and Juniper?
In early 2014 I got in touch with Cisco and I left Continue reading

Recently I attended a workshop organised by the Open NFP organisation about Data Plane acceleration. The primary goal of the workshop was to get students and researchers (why was I there you may think) familiar with the P4 programming language.
P4 is a programming language created to simplify writing data planes for networking use cases. Recently the P4-16 spec was released and could be considered a mature version of the language.
Now I’m not a hardcore developer. I know my way around in Python, GoLang and C#, but I never wrote anything more low level like C. P4 is created a little bit like GoLang, where I do not mean it as comparison, but as an architecture. P4 is designed so you only need to focus on the actual networking features that you want to make available on the hardware you are programming it for. Then when you compile it, it will generate runtime code for your hardware. Or as the creators explain it:
At one level, P4 is just a simple language for declaring how packets are to be processed. At another level, P4 turns network system design on its head.
There is no need to worry on low Continue reading
