Due to the fact that the Bandwidth Splitter control tools integrate into the Forefront TMG Management console and the application management principles are alike, you can hardly have any problems with getting started with it.
|Warning. If the Forefront TMG Management console has stayed open during installation of Bandwidth Splitter, it is necessary to close and reopen it after installation to be able to access the new Bandwidth Splitter section.|
After Bandwidth Splitter has been installed, the Forefront TMG Management console looks as follows:

A new section, Bandwidth Splitter, has appeared in the console tree. This section includes the following subsections:
Initially Bandwidth Splitter contains no shaping or quota rules. By default such a configuration means that all users and computers are not restricted by both bandwidth and traffic amount yet. And you won't see anything in monitoring section yet.
|Note. Bandwidth Splitter does not make it unnecessary to set up the basic options of Forefront TMG. Bandwidth Splitter only adds own rules to the set of already available in Forefront TMG. Therefore it is necessary to make sure that Forefront TMG is correctly configured before testing the new features provided by Bandwidth Splitter.|
Next you can set up Shaping Rules and Quota Rules at own discretion. For example, create a new shaping rule. Give it any name you wish.
At Applies To page specify users or IP address sets, to which this rule will apply.
|Warning. Bear in mind your license restrictions, and don't specify user groups or IP address sets that include more clients than your license allows.|
|Warning. To make work Bandwidth Splitter rules that have users or user groups (not IP address sets) in the Applies To field, those users should be authenticated. For this purpose they should be allowed in generic Firewall Policy Rules as authenticated users, that is at Users tab you should specify something other than All Users, for example All Authenticated Users.|
At Destinations page, select External network.
At Schedule page, select Always.
At Shaping page, select Shape total traffic (incoming+outgoing) and enter the maximum speed in kilobits per second into the field Total (kbits/s), for example 64.
Leave other fields with default values. Click Finish to complete wizard.

Bandwidth Splitter stores its configuration in Forefront TMG storage. So when you make changes, you should apply them (or discard) when finished. You can do it using standard Apply and Discard buttons. When Bandwidth Splitter sections are selected those standard buttons are invisible, but you may use analogous buttons at toolbar. They look like this: .
Click Apply Changes button. Bandwidth Splitter filters will pick up the changes, and if some user was downloading a big file at an unlimited speed, and shaping rule you have just created applies to this user, the situation will change now and the speed for this user will be limited to 64 kbits/s. If the user has several open connections, this speed will be distributed evenly for all active connections.

|Note. In Bandwidth Splitter monitoring you will see only connections to which some Shaping and/or Quota rule is applied. If neither Shaping nor Quota rule is found for some connections, they won't be filtered by Bandwidth Splitter, and you won't see them in monitoring.|
Such is the introduction to Bandwidth Splitter. Read the rest of sections to learn more about the features and the use of Bandwidth Splitter.
