20 Chapter 1 Mac OS X Server in Action
 The directory and network services in each network reside on one Mac OS X Server,
and a second server hosts mail, web, and other employee productivity services. In
small businesses, all services might reside on a single server.
 Setting up basic network services, such as the Network Address translation (NAT),
firewall (IP filter), DHCP, and DNS services in this scenario, are easy thanks to Gateway
Setup Assistant. This tool configures a server as a gateway, linking a local area
network (LAN) to the external Internet and letting you share a server’s Internet
connection among computers on the LAN.
 The firewall between Mac OS X Server and the Internet protects the company
intranet from access by unauthorized users.
 An authoritative DNS server hosted by another company provides domain name
(example.com) resolution. DNS services on Mac OS X Server provide names for the
intranet devices (such as printers and client computers) that have static IP addresses
and cache DNS lookups for faster name resolution.
 DHCP services provide dynamic IP addresses to some of the Macintosh and Windows
clients.
 Like all the other services shown, VPN supports both Macintosh and Windows clients.
If the organization uses a lot of Windows computers, you can set up Mac OS X Server
as a Primary Domain Controller (PDC) so you can host Windows home directories.
 NAT service lets employees share a single Internet connection. NAT converts all client
IP addresses to one IP address for Internet communications.
 Web service’s proxy caching speeds up response times and reduces network traffic
by storing recently accessed files in a cache on the web server so they can be
retrieved quickly when requested again.
 You can customize what users see in the Finder when they select the Network icon in
the sidebar of a Finder window by defining managed network views. Managed
network views simplify finding files and folders that reside on network servers when
they’re used to list network resources in a fashion meaningful to users.
