6 3 AstroFlowGuard - Step by Step Bandwidth Management 1 Introduction 1.1 Introduction The AstroFlowGuard Bandwidth Management module is incredibly easy to use once you have familiarised yourself with the way the system works. This quickstart guide will give you a step by step method of setting up basic bandwidth management. Real world examples For the purpose of the example, we will create 4 classes of 32 Kbit to manage the following : 1. Limit a single IP Address to 32 Kbit Incoming and 32 Kbit Outgoing. 2. Limit an IP Address range to 32 Kbit Incoming and 32 Kbit Outgoing. 3. Limit a specific port to 32 Kbit Incoming and 32 Kbit Outgoing. 4. Limit P2P (Peer to Peer) Kazaa traffic to 32 Kbit globally. Variables In this guide, we will assume a local network of with a subnet mask of Continue to Step 1

7 Part II

8 5 AstroFlowGuard - Step by Step Bandwidth Management 2 Step by Step Bandwidth Management 2.1 Step 1 - Local Subnets N.B. This step is critical for the function of AstroFlowGuard. AstroflowGuard needs to know all your local subnets in order to manage them. To add your local subnets follow the steps below : Select "System Configuration -> Network Settings -> List Local Subnets" from the menu. Click "Add Local Subnet". Enter the correct values for your local subnet and click "Add Host". You will see the subnet you have just added in the Local Subnet List. Continue to Step Step 2 - Host Manager The purpose of the Host Manager The sole purpose of the Host Manager is to simplify large, complex AstroFlowGuard configurations. Although it is not necessary to use the Host manager, it is highly recommended as it provides a central repository for all hosts / networks that you need to manage. A classic example of the benefits of the Host Manager is a case where you have fully configured your AstroFlowGuard system, and now need to change the IP address of one of your hosts - you would simply change that hosts IP address in the Host Manager and those changes will be replicated throughout the system. Adding hosts via Host Manager

9 Step by Step Bandwidth Management Adding a Single IP host For the purpose of our example, we will add 2 hosts via Host Manager, 1 host with a single IP Address and 1 Host that covers a range of IP Addresses. Adding a host with a single IP Address: Select "Host Manager -> List Hosts" from the menu. Click on the "Add" button. Enter details for the host. Note: We will select a subnet mask of as this is a single IP host. Click "Add host". You will see the configured host in the host list. Continue to next step Adding an IP range host Adding a host that covers an IP Address range: From the host list, click on the "Add Host" button. Enter details for the host. Note: We will select a subnet mask of which will cover a range of 6 IP Addresses. ( > in this case) Click "Add host".

10 7 AstroFlowGuard - Step by Step Bandwidth Management You will see the configured host in the host list. Continue to Step 3 - Classes Table of Common Subnet Masks I 2.3 Step 3 - Classes Subnet Mask The purpose of Classes Mask Bits The AstroFlowGuard Bandwidth Management module makes use of "Classes" to apply bandwidth restrictions. The two default classes are "Incoming" and "Outgoing", custom classes are created under these classes to apply specific restrictions.for more information regarding classes, please see Chapter 7 of the AstroFlowGuard Manual. For the purpose of the examples, we will create the following classes: Under Incoming : Kbit Single IP Kbit IP Range Kbit Port Kbit P2P Under Outgoing : Kbit Single IP Kbit IP Range Kbit Port Note: When limiting P2P, only an Incoming class is created - this will manage both Incoming and Outgoing P2P traffic. Continue to Adding Classes

11 Step by Step Bandwidth Management Adding Classes We will now add our four classes specific to this example. Select "Bandwidth Manager -> Manage Bandwidth" from the menu. Continue to Adding the 32 Kbit Single IP Class Adding the 32 Kbit Single IP Class In the tree menu in the left pane, click on the "Incoming" node. Click on the "Add Class" button in the right pane. (Class List) Enter the following data for this class: Class Name: Guaranteed Rate: Burst Rate: Queueing Discipline: Add to Outgoing Class: 32 Kbit Single IP 32 Kbit Leave Blank Leave Default (Stochastic Fairness Queueing) Select "Outgoing"

12 9 AstroFlowGuard - Step by Step Bandwidth Management Click "Add Class" Your Class will appear in the Class list pane on the left. Continue to adding the 32 Kbit IP Range Class Adding the 32 Kbit IP Range Class In the tree menu in the left pane, click on the "Incoming" node. Click on the "Add Class" button in the right pane. (Class List) Enter the following data for this class: Class Name: Guaranteed Rate: Burst Rate: Queueing Discipline: Add to Outgoing Class: 32 Kbit IP Range 32 Kbit Leave Blank Leave Default (Stochastic Fairness Queueing) Select "Outgoing" Click "Add Class" Your Class will appear in the Class list pane on the left. Continue to Adding the 32 Kbit Port Class

Click "Add Class" You will now see all your classes listed in the Left "Class List" pane. Continue to Step 4 - Filters

15 Step by Step Bandwidth Management Step 4 - Filters The purpose of Filters The filters in AstroFlowGuard define which traffic will be managed by the class that the filter falls under. Example: We want to limit to 32 Kbit Incoming, so we create a filter with the destination host of netmask under the 32 Kbit Class. All traffic with a destination address of will be limited to the 32 Kbit as configured in the class. Continue to Adding the Single IP Filter Adding Filters Enter topic text here Adding the Single IP Filter In the tree menu in the left pane, click on the "Incoming / 32 Kbit Single IP" node. All filters assigned to this class will be listed in the right "class list" pane. Click on "Add Filter".
