Understanding Transport Layer Security (TLS) is essential for Always On VPN administrators. TLS (formerly Security Sockets Layer, or SSL) is used not only for Secure Socket Tunneling Protocol (SSTP), the protocol of choice for the Always On VPN user tunnel in most deployments, but many other technologies such as secure websites and email, Remote Desktop Protocol (RDP), secure LDAP (LDAPS), and many more. High-quality, affordable TLS training is challenging to find, however.

TLS 1.3
The Practical TLS training course does not yet include a module on the newest TLS protocol, TLS 1.3. However, it is due out imminently! Ed is working on the content as we speak, and a preview module is included in the course today. Look for the final TLS 1.3 module soon.
Bonus Content
In addition to excellent TLS training, the course includes free OpenSSL training! Administrators working with certificates in non-Microsoft environments are sure to find this helpful. Understanding OpenSSL will benefit administrators working with network and security appliances such as firewalls and load balancers.

Updated December 9, 2023: I’ve recently updated this PowerShell script to work more reliably in different configurations other than the Getting Started Wizard. If you’ve had trouble running this script in the past, download the latest version. It should work better! I’ve also published the script in the PowerShell gallery. You can install it by running “Install-Script Renew-DaSelfSignedCertificates”. Enjoy!
When Always On VPN clients are configured to use the Secure Socket Tunneling Protocol (SSTP) with Windows Server Routing and Remote Access Service (RRAS), administrators may encounter a scenario in which a client can establish a VPN connection using SSTP successfully, but is then disconnected immediately. The system event log contains an entry with Event ID 6 from the RasSstp source that includes the following error message.
