7.4.2 SOHO Network to Internet Access

To connect a small office or home office (SOHO) network to the Internet, you can use one of two
methods:

1. Routed connection: For a routed connection, the server running Routing and Remote
Access acts as an IP router that forwards packets between SOHO hosts and Internet hosts.
This scenario describes a small office or home office (SOHO) network that connects to the
Internet by using a routed connection.
A SOHO network has the following characteristics:
(a) One network segment.
(b) A single protocol: TCP/IP.

(c) Demand-dial or dedicated-link connections to the Internet service provider (ISP).
The following illustration shows an example of a SOHO network.
Figure 7.5: SOHO Network

The server running Routing and Remote Access is configured with a network adapter for the
media that is used in the home network (for example, Ethernet) and an ISDN adapter or an
analog modem. You can use a leased line or other permanent connection technologies, such as
xDSL and cable modems, but this scenario describes the more typical configuration that uses a
dial-up link to a local ISP.

For a translated connection, server running Routing and Remote Access and NAT acts as a
network address translator, an IP router that translates addresses for packets that are forwarded
between SOHO hosts and Internet hosts.
