By default, the modem router functions both as a modem and a router. You can change the 
operation mode to a mode in which the modem router functions as a DSL modem only with 
the routing, firewall, wireless support, and traffic meter features disabled.

A typical use of such a mode is when the modem router is used for DSL connectivity only 

behind a router, firewall, or security device manager that provides routing, firewall, wireless 
support, and traffic meter features.
