Quality of Service & Policy Configuration
QoS Overview
The Twin WAN Gateway provides the Quality of Service (QoS) feature which supports high quality of network service. Classifying outgoing packets based on user-defined policies provides real-time applications to get better response or performance.

Quality of Service - Settings
Enable QoS - This enables the QoS function.
Queuing Method -
The Twin WAN Gateway supports the widely used Priority Queuing method. This method immediately services user-defined packets with a higher queue priority.
Process TOS Field -
An 8-bit field in the IP packet header is designed to contain values indicating how each packet should be handled in the network. Selecting enable will process the IP Type of Service field.
Overwrite Policy Priority -
Choosing Yes will set the priority of the TOS field in IP packet to overwrite the priority defined in policy configuration.
Policy Configuration
When you use QoS, you must define some policies to select which packets to give a higher priority to pass through.

Policy Configuration - Settings
To edit an existing entry, select it from the list and click the Select button. The data fields will then be updated with data for the selected entry.
Enter a suitable name a new policy. Generally, you should use the Policy Name for the network traffic you wish to give a high priority.
Define the source address of packets here. The Twin WAN Gateway supports two source address types- IP address or MAC address. Selecting IP address permits you to define IP address range. The gateway allows up to four define MAC addresses.
Define the destination address of packets here. The Twin WAN Gateway supports two destination address types- IP address or MAC address. Selecting IP address permits you to define IP address range. The gateway allows up to four define MAC addresses.
The field defines traffic packet type- IP, TCP, and UDP.
Define the source port of the packets in this field.
Define the destination port of the packets in this field.
This defines the priority level of the current Policy Configuration. Packets associated with this policy will be serviced based upon the priority level set. For critical applications High or Medium levels are recommended. For non-critical applications select a Low level.
