1. WFilter requires a web browser to access its web interface. A browser version like IE 5.5(firefox 2.0) or higher is recommended. Using older browser may cause WFilter web interface display incorrectly.

2. WFilter needs to create TCP ports 9090 and 9091. As many firewall programs do not allow programs to access the network by default. If you fail to launch WFilter, please  shutdown your firewall program and re-install WFilter.

3. If this is your first time using WFilter, we recommend you to read "Getting Started With WFilter" first. Please visit this url: http://www.imfirewall.us/WFilter_Step_by_Step_Guide.htm
