Shared Internet connection with a router acting as a gateway
In this example, a router manages the network connections and acts as a
gateway between the network and the Internet.
Shared Internet connection with a computer acting as a gateway
In this example, the network devices are connected to a hub . A Macintosh OSX
computer on the network acts as the gateway between the network and the Internet.
The gateway computer uses Internet Sharing to manage the network connections
and provide Internet access to the other devices.
DSL or cable Internet connection without a gateway
This example looks similar to the first example. However, in this example, the
network devices are connected to a hub , rather than a router . The hub is directly
connected to the Internet.
Caution: HP does not recommend this configuration. If possible, use a
gateway to manage your network's Internet access in order to limit exposure
to viruses and guard against unwanted entry.
