"I'm thinking of setting up a LAN in my new house and interested in getting DSL.

"If I connect to DSL via a router such as the Linksys, can every host in my house make a connection by itself?"

Linksys Router Configuration

In networking, nearly all hardware and software requires some form of configuration. The Linksys router is no exception. After plugging in power and network cabling, a number of Linksys settings must be applied by the network administrator. Settings include the external (public or WAN) addressing for the cable or DSL service including Domain Name System (DNS) server addresses and PPPoE entries for DSL providers that require it.

The Linksys uses a built-in Web server to simplify its configuration. Once the hardware has been connected and powered on, the Linksys administrative interface is reached initially by accessing the well-known internal IP address 192.168.1.1:
http://192.168.1.1/

The Linksys router historically has undergone frequent updates to its firmware. Beginning with version 1.30, Linksys added a remote administration feature to the product. Instead of reaching the built-in Web server from the internal LAN address, an administrator can access the Linksys router configuration page at its external address on port 8080, such as

http://209.143.212.20:8080
