Chapter 3
Internet Access
This chapter shows you how to configure the LAN as well as the WAN of your Prestige for
Internet access.
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 3.3 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 TCP/IP Parameters
3.2.1 IP Address and Subnet Mask
Similar to the houses on a street that share a common street name, the machines on a LAN share
one common network number, also.
Where you obtain your network number depends on your particular situation. If the ISP or your
network administrator assigns you a block of registered IP addresses, follow their instructions in
selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single
user account and the ISP will assign you a dynamic IP address when the connection is
established. If this is the case, it is recommended that you select a network number from
192.168.0.0 to 192.168.255.0 (ignoring the trailing zero) and you must enable the Single User
Account feature of the Prestige. The Internet Assigned Number Authority (IANA) reserved this
block of addresses specifically for private use; please do not use any other number unless you
