Setting Up Traffic Shaper
To set up Traffic Shaper
1. Enable Traffic Shaper for the Internet connection, using the procedure Using
Internet Setup on page 141.
You can enable Traffic Shaper for incoming or outgoing connections.
• When enabling Traffic Shaper for outgoing traffic:
Specify a rate (in kilobits/second) slightly lower than your Internet connection's
maximum measured upstream speed.
• When enabling Traffic Shaper for incoming traffic:
Specify a rate (in kilobits/second) slightly lower than your Internet connection's
maximum measured downstream speed.
It is recommended to try different rates in order to determine which ones provide the
best results.
Note: Traffic Shaper cannot control the number or type of packets it receives from the
Internet; it can only affect the rate of incoming traffic by dropping received packets.
This makes the shaping of inbound traffic less accurate than the shaping of
outbound traffic. It is therefore recommended to enable traffic shaping for incoming
traffic only if necessary.
2. If you are using a Safe@Office product with Power Pack, you can add QoS
classes that reflect your communication needs, or modify the four predefined
QoS classes.
See Adding and Editing Classes on page 298.
Note: If you are using Safe@Office 1000N, you have Simplified Traffic Shaper, and
you cannot add or modify the classes. To add or modify classes, upgrade to
Safe@Office with Power Pack, which supports Advanced Traffic Shaper.
3. Use Allow or Allow and Forward rules to assign different types of connections
to QoS classes.
For example, if Traffic Shaper is enabled for outgoing traffic, and you create an Allow
rule associating all outgoing VPN traffic with the Urgent QoS class, then Traffic
