Info sheet: NAT/mobile tethering transparency plug-in to uncover mobile tethering fraud

Detecting network address translation (NAT) and the devices behind a NATing device

RS_image_resources-feature-card-NAT

Detecting network address translation (NAT) and the devices behind a NATing device is difficult. Routers, wireless access points or smartphones with enabled tethering option map multiple devices to one publicly exposed IP address. With the new NAT/ mobile tethering transparency plug-in, network solution manufacturers can now enhance their solution with cutting-edge IP traffic analytics to reveal devices behind a NATing device and tethering fraud in a specific network.

The easy-to-integrate software plug-in in combination with our leading OEM DPI software R&S®PACE 2 detects NATing and devices behind the corresponding routing device, as well as the applications used, in order to uncover mobile tethering fraud. This is not only important for the fraud control itself but fraudulent and abusive tethering consumption leads to negative network effects and degraded quality-of-experience for CSP’s customers. Using our NAT/ mobile tethering transparency technology, communication service providers can prevent, detect and stop data abuse through "tethering" and increase customer satisfaction while maximizing their own efficiency and profitability.
