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  TCP/IP and DHCP for LAN 
The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that 
support DHCP client capability. 
3.1.1  Factory LAN Defaults 
The LAN 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 your ISP gives you explicit DNS server 
address(es), skip to the DNS Server Address section to see how to enter the DNS server address(es).  
3.1.2 DHCP Configuration 
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain 
TCP/IP configuration at start-up from a server. You can configure the Prestige as a DHCP server or disable 
it. When configured as a server, the Prestige provides the TCP/IP configuration for the clients. If set to 
None, DHCP service will be disabled and you must have another DHCP server on your LAN, or else the 
workstation must be manually configured. The Prestige can also act as a surrogate DHCP server (DHCP 
Relay) where it relays IP address assignment from the actual real DHCP server to the 
clients
