HOW TO use the cFos Traffic Shaper with NAT32.

After installing or upgrading the cFos Traffic Shaper Driver, a Windows reboot is required to restart the NAT32 NDIS3PKT Driver.

Introduction

CFOS V.3 is an advanced Traffic Shaper that dynamically allocates network bandwidth amongst networking applications. This speeds up overall network performance and ensures that high-bandwidth apps such as FTP do not cause starvation in other communicating applications.

CFOS also functions as a Firewall for your DSL Connection. It differs from the Windows Firewall in that it examines both incoming and outgoing traffic, and it filters all DSL traffic, not just Winsock traffic as does the Windows Firewall.

Commands

NAT32 Build 1039 and higher contains a cfos command that lets you interact with the cFos Driver. The supported command set is:
