The multi-WAN models support this on their Ethernet WAN interface for selected models; however, if you turn on Hardware Acceleration, the accelerated traffic will by-pass the following features: Traffic Graph, WAN Budget.

On the other hand, when Data Flow Monitor, QoS or Bandwidth Limit is enabled, the function of Hardware Acceleration will not take effect, if it is enabled, to prevent from session conflicts.

Modes of Hardware Acceleration

DrayOS provides two options for Hardware Acceleration, Auto and Manual. In Auto mode, Hardware Acceleration will automatically apply to the heaviest TCP sessions. In Manual mode, the network administrator can choose to accelerate the sessions of a certain protocol, source IP, or QoS class.

How do I know if Hardware Acceleration is working?

To check whether Hardware Acceleration is working or not, you can type ppa -v in router's CLI. The numbers of PPA LAN and WAN are the accelerated traffic.

Furthermore, type ppa -d 3 to see if Hardware Acceleration is working on a session from LAN, and ppa -d 4 to see if it is working on a session from WAN.
