About This Manual
This manual contains information on the syntax and use of the Command Line Interface for the family of DSL
routers. Configuration of network connections, bridging, routing, and security features are essentially the same for
all DSL routers, unless otherwise noted.
This manual is intended for small and home office users, remote office users, and other networking professionals
who are installing and maintaining bridged and routed networks.
It assumes that you have read the Quick Start Guide that came with the router and have installed the router as
described in that guide.
