Figure 10.2. FwdFast Rules Bypass Traffic Shaping
Using Pipes with Application Control
When using the Application Control feature, it is possible to associate a pipe object directly with
an Application Rule object in order to define a bandwidth for a particular application. For
example, the bandwidth allocated to the BitTorrent peer-to-peer application could be limited in
this way.
This feature is discussed further in Section 3.7, “Application Control” .
10.1.3. Simple Bandwidth Limiting
The simplest use of pipes is for bandwidth limiting. This is also a scenario that does not require
much planning. The example that follows applies a bandwidth limit to inbound traffic only. This
is the direction most likely to cause problems for Internet connections.
Example 10.1. Applying a Simple Bandwidth Limit
Begin with creating a simple pipe that limits all traffic that gets passed through it to 2 megabits
per second, regardless of what traffic it is.
Command-Line Interface
gw-world:/> add Pipe std-in LimitKbpsTotal=2000
Web Interface
1. Go to: Policies > Traffic Management > Pipes > Add > Pipe
2. Specify a suitable name for the pipe, for instance std-in
3. Enter 2000 in the Total textbox under Pipe Limits
4. Click OK
