F5 APM - limiting access to the bandwidth for network Access

The "Client Interface Speed" feature was primarily designed for specific functionalities in older Windows versions:
That includes:

• Helping the OS adjust the TCP receive window size.
• Displaying the interface speed in a taskbar tooltip pop-up when hovering over network adapters.

With the advent of Windows 10, there were significant changes in how the OS managed TCP-related features. Consequently, the "Client Interface Speed" setting became less influential.

If your goal is to adjust the bandwidth of the VPN connection, please see the Creating a client rate class section of Shaping Traffic on the Network Access Client article.
