Cable/DSL Router
Congratulations on the purchase of the EtherFast Cable/DSL Router from
Linksys! The Router is the perfect solution for connecting a network of PCs to
a high-speed broadband Internet connection and to an Ethernet network back-
bone. Configurable as a DHCP server for your network, the Router is the only
visible network device on the Internet. The Router also serves as your Internet
NAT firewall, protecting your network’s PCs from being accessed by external
users. All incoming data packets are monitored and filtered. The Router can
also be configured to block internal users’ access to the Internet with IP filter-
ing, as well as to play Internet games, videoconference, and much more. Plus,
the Router supports Universal Plug and Play (UPnP), which allows Windows
XP to automatically configure the Router for various Internet applications,
such as videoconferencing and gaming—making the Router a snap to use.
