Always On VPN RRAS Internal Interface Non-Operational

Windows 10 Always On VPN Routing Configuration

Always On VPN administrators troubleshooting connectivity issues may find the Internal network interface in the Routing and Remote Access management console (rrasmgmt.msc) administrative status indicates ‘Unknown’. They will also notice the Operational Status shows Non-operational.

Internal Interface

For clarification, the ‘Internal’ network interface in the Routing and Remote Access management console, as shown above, is not a physical network adapter on the server. Instead, it is a virtual network interface used only for incoming VPN connections.

Non-Operational

The Internal virtual network interface will not be created until the VPN server accepts its first VPN connection. Because of this, the Internal interface will have an operational status of non-operational until the first client attempts to connect. When this occurs, RRAS creates the interface, then assigns it the first IP address from the static IPv4 address pool. Alternatively, if DHCP is configured, it will assign the first IP address returned by the DHCP server.

Interface Names

While discussing network interfaces, I typically recommend renaming them in Windows to identify their function, especially when using two NIC configurations. However, be careful not to name the server’s internal network adapter ‘Internal’, as this can be confusing in the future. In my example above, I use the name ‘LAN’ to identify the internal adapter to distinguish it from the server’s ‘Internal’ virtual interface.

SSL and TLS Training for Always On VPN Administrators

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.

UPDATE! This course has been further discounted for a limited time. Details below!

Practical TLS

Thankfully, Ed Harmoush from Practical Networking has a fantastic training course called Practical TLS that meets these requirements. It is the most comprehensive TLS training course I’ve seen and is surprisingly affordable too!

Course Content

The Practical TLS training course includes the following modules.

  • Module 1 – SSL/TLS Overview (free preview!)
  • Module 2 – Cryptography
  • Module 3 – x509 Certificates and Keys
  • Module 4 – Security through Certificates
  • Module 5 – Cipher Suites
  • Module 6 – SSL/TLS Handshake
  • Module 7 – TLS Defenses

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.
