Anthony Burke gives a little bit of a sneak peek at some functionality from the upcoming v3 release of PowerNSX: searching NSX Distributed Firewall (DFW) rules. The article supplies lots of useful information, but I really would’ve liked some concrete examples of how to glue these pieces together. Cody De Arkland shows you how.

Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. Here’s a walkthrough to install Arch Linux on VirtualBox. Alan Renouf shows you how to retrieve NVMe storage device details using PowerCLI. What’s that?

Here’s a handy post by Dale Coghlan on how to find object IDs for just about anything in a VMware NSX environment. The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up.
