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.

3.2.1
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.
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.
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 are told otherwise. Let’s say you select 192.168.1.0 as the network number; which covers
254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the
first 3 numbers specify the network number while the last number identifies an individual workstation on that
network.

Once you have decided on the network number, pick an IP address that is easy to remember, e.g.,
192.168.1.1, for your Prestige.
