This chapter shows you how to configure the LAN as well as the WAN of your Prestige for Internet
3.1

Factory Ethernet Defaults

The Ethernet parameters of the Prestige are preset in the factory with the following values:
1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to section 3.4 TCP/IP Ethernet Setup and DHCP to enter the DNS server address(es) if your ISP gives
you explicit DNS server address(es). If you wish to change the factory defaults or to learn more about
TCP/IP, please read on.
3.2 LANs & WANs
A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand is an outside connection to
another network or the Internet.

3.2.1 LANs, WANs and the Prestige

The actual physical connection determines whether the Prestige ports are LAN or WAN ports. There are two
separate IP networks, one inside, the LAN network; the other outside, the WAN network as shown next.
