How to submit support file of WFilter?

Due to complicated settings and network topology, it’s not easy to describe a question of WFilter.

For us to understand your question easier, we recommend you to use the “support” feature of WFilter to submit your support request. The “support” feature will gather required settings and network packets samples for diagnose purpose. So we can locate the problem quickly.

It’s simple to submit a support request. In most case, you only need to describe your question and click “submit”. (Figure 1)

In case when your question is related to a certain behavior(for example, email sending is not recorded), we will need a packet dump of this behavior.

You need to check “Add packet dump file(s)”, and click “Restart Capturing” for WFilter to start packet capturing. (Figure 2)

The default packet dump captures packets of all client computers. To make it simple, you’re recommended to capture packets for the testing client computer only. (Figure 3)

We will reply you by email when we get your support request.

How to monitor and filter internet activities of PPPOE users?

PPPOE is widely used for user authentication and traffic accounting. However, it’s a little difficult to monitor and filter PPPOE clients’ internet usage and behavior.

In this example, we will demonstrate you to monitor and filter PPPOE clients with WFilter Free. Please notice that only non-encrypted and uncompressed PPPOE traffic can be supported. So the first step is to configure your PPPOE server for non-encryption and non-compression.

1. PPPOE server settings

Let’s take windows 2003 and RouteOS for examples.

1). 2003 Server Configuration

If you are using windows 2003 server as the PPPOE server, please follow below steps to configure:

In “Properties” of the “Routing and Remote Access”, disable “software compression” and “LCP” in the “PPP” tab.

Edit “remote access policy” for “no encryption” in “Edit Profile”. Notice: The default two policies shall all be modified.

2). ROS Configuration

If you are using routeOS as PPPOE server, please follow these steps to disable compression and encryption:

In “PPP” tab of “Profiles”, click “Protocols” and disable compression and encryption.

2. Monitor PPPOE clients in WFilter

2.1) Choose the internal adapter

Now WFilter is able to parse PPPOE traffic. In this example, we just install WFilter free in the windows 2003 PPPOE server.

You need to choose the internal adapter as the “monitoring adapter” in “System Settings”->”Monitoring Settings” of WFilter.

2.2). Setup client policy

Add a block policy to block web surfing.

Apply this policy to PPPOE clients’ ip ranges

2.3). Check Blocking

PPPOE clients get blocked.

Blocking events in WFilter.
