VMware NSX-T Data Center 3.1 Security exam guide

After attending VMware EMPOWER earlier this year, I won a voucher for a free exam (thanks EMPOWER team!). I chose the NSX-T 3.1 Data Center Security exam because of personal interest and exciting security features NSX offers. While preparing for the exam I gathered a list of study materials I wanted to share with you all. The voucher expired on the 31st of August, but got it in mid-July during my PTO. So, work to Read more…

IPv6 Series: Part 5 – IPv6 with NSX-T

In this IPv6 series I’d like to tell you about my “journey” to implement the protocol at home and in the lab. This part explains how IPv6 can be used with NSX-T in the datacenter. Expect the creation and / or configuration of T0 and T1 routers, Uplink configuration, Static upstream routing and Segments while touching ND profiles and IP autoconfiguration in related posts. Let’s go to the bits. The Series The first two parts Read more…

NSX-T: IPv6 Autoconfiguration explained

Today’s NSX-T topic is about automatically configuring hosts with IPv6 addresses. During the writing of my IPv6 series, I wondered what options are available in NSX-T and which use-cases they serve. The full list on IPv6 posts can be found here: IPv6 posts. In a IPv4 network, DHCP is used widely to automatically configure IP addresses and additional IP stack options like DNS servers / suffix, NTP, PXE or for IP based phones. In the Read more…

NSX-T Tidbits: IPv6 feature support

In this part of the NSX-T tidbits series, it’s about the current IPv6 support. During the writing of my IPv6 series, I needed to know which features are currently support in the current (3.1) version and found out there isn’t a good overview of it. After digging into blog posts the NSX documentation and release notes, I created the list below. If some features are missing, just let me know, so I can add them. Read more…

IPSec config and phases overview

IPv6 Series: Part 4 – IPSec VPN

In this IPv6 series I’d like to tell you about my “journey” to implement the protocol. I already had some knowledge of it, but not extensively. As a first step IPv6 is implemented at home. The plan is to work my way back from home to my lab in the data-center. The previous parts describe the basics and how to implement IPv6 in my home network using a tunneling technique called 6RD. Using the 6RD Read more…

Change AD password on macOS via Remote Desktop

You probably know the feeling, when you’re trying to do something uber standard, but you’re struggling with it. It’s extra annoying because you know, it should be simple (which it eventually is 🙃). I had just that feeling this week when I needed to change my AD password using a my MacBook. After getting a notification that one of my corporate passwords is about to expire, I logged-in to one of the stepping stone hosts Read more…

IPv6 Series: Part 2 – IPv6 at home using 6RD

In this IPv6 series I’d like to tell you about my “journey” to implement the protocol. I already had some knowledge of it, but not extensively. As a first step I implemented it at home. The plan is to work my way back from home to my lab in the data-center. In the previous part of this series, I discussed the IPv6 basics that in my opinion matters the most when starting to implement the Read more…

IPv6 Series: Part 1 – IPv6 Primer

Not due to shortages in IPv4 address, because that’s relative (looking at the 4 million IPv4 addresses Amazon bought this year from AR|DC‘s AMPRNet), but more due to personal interest and being able to equip all your devices with public IP’s (and not having to use NAT masquerading) is interesting. During my PTO, I had some spare time, so it’s time to implement IPv6 at home and in the lab. I always had a great Read more…
