Sharing a broadband Internet connection using a cable/dsl router

Using a cable/dsl router to share your Internet connection simplifies security.  As shown below, the LAN is separated from the WAN (internet) by the router witch acts as a firewall.  The example below shows a router that has an ethernet switch built in.  If you purchase a router with enough ports for all your computers, an extra hub or switch is not needed (but can be added later for more ports)
