Prestige 791R G.SHDSL Router 
LAN   6-3 
3.  Out Only - the Prestige will send out RIP packets but will not accept any RIP packets received. 
4.  None - the Prestige will not send any RIP packets and will ignore any RIP packets received. 
The Version field controls the format and the broadcasting method of the RIP packets that the Prestige 
sends (it recognizes both formats when receiving).  RIP-1 is universally supported; but RIP-2 carries more 
information.  RIP-1 is probably adequate for most networks, unless you have an unusual network topology. 
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses 
subnet broadcasting while RIP-2M uses multicasting. 
6.1.5 DHCP Configuration 
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the 
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server 
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS 
servers to Windows 95, Windows NT and other systems that support the DHCP client. The Prestige can 
also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to 
the clients. 
IP Pool Setup 
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for 
the client machines.  This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself 
which has a default IP of 192.168.1.1) for other server machines, for example, server for mail, FTP, telnet, 
web, etc., that you may have. 
DNS Server Address 
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, 
for example, the IP address of www.zyxel.com is 204.217.0.2.  The DNS server is extremely important 
because without it, you must know the IP address of a machine before you can access it.  The DNS server 
addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP 
address and subnet mask. 
There are two ways that an ISP disseminates the DNS server addresses.  The first is for an ISP to tell a 
customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up.  If
