Changing the default HTTP(s) Reverse Proxy Ports on ESXi 8.0 Update 1

07.31.2023 by William Lam // 8 Comments

Pre-ESXi 8.0 Update 1, if you needed to modify the default ESXi HTTP(s) Reverse Proxy Ports, you would simply edit the HTTP reverse proxy configuration file, which I have previously blogged about HERE (pre-ESXi 8.0) and HERE (ESXi 8.0).

For ESXi 8.0 Update 1, the process is slightly diffrent as all ESXi configurations including configuration files have been completely migrated to the new ESXi Configuration Store, which was initially introduced back in vSphere 7.0 Update 1, which you can learn more about it HERE and HERE.

While most users stick with the system defaults with port 80 (HTTP) and port 443 (HTTPS), I know there are some organizations that require these ports to be changed to meet certain internal compliance requirements. Below are the updated instructions for modifying the ESXi HTTP(s) Reverse Proxy Ports when using ESXi 8.0 Update 1 or later.

Disclaimer: VMware does not officially support modifying the default HTTP/HTTPS ports on an ESXi host.

vSphere 8.0 Update 1c was just released and one of the resolved issues mentioned in the ESXi release notes is the following:

Nested virtual machines on AMD CPUs with operational systems such as Windows with virtualization-based security (VBS) might experience performance degradation, timeouts, or unresponsiveness due to an issue with the virtualization of AMD's Rapid Virtualization Indexing (RVI), also known as Nested Page Tables (NPT).

UPDATE (10/11/23) - This is also resolved in the ESXi 7.0 Update 3o release

There are two scenarios in which this fix resolves:

  1. Running Windows Server VM with a Hyper-V enabled Generation 2 VM (Nested Virtualization) on AMD CPU
  2. Running Windows Server VM with VBS Enabled (Non-Nested VM) on AMD CPU

Quick Tip - Retrieving the vSAN Rekey Interval using PowerCLI

07.26.2023 by William Lam // Leave a Comment

Since the release of vSAN 6.5.1, the PowerCLI team has introduced a number of high level vSAN cmdlets (current list HERE) that can be used to automate a variety of tasks. While the existing vSAN cmdlets are quite extensive and continues to get updated with new functionality, it will never be able to cover the rich set of functionality that is provided by vSAN.

For functionality that is not available in the high level vSAN cmdlets, user can still perform the task using PowerCLI, but they will need to directly access the underlying API, in this case the vSAN Management API.

Note: This concept also applies to other high level PowerCLI cmdlets, if you are unable to locate the functionality, then most likely you will need to interrogate the API using PowerCLI.


In the case of retrieving the vSAN Data-in-transit encryption rekey interval, which is not available in the high level Get-VsanClusterConfiguration cmdlet, we can easily retrieve it with the following PowerCLI snippet:
