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 which acts as a firewall. The example below shows a
router that does not have an ethernet hub/switch built
in. If you purchase a router without enough ports for all your computers,
an extra hub or switch
can be connected easily. Just run a standard
ethernet cable from your hub/switch UPLINK
port to your routers LAN port. |
