Prestige 792H G.SHDSL Router 
WAN   3-9 
 Regardless of your particular situation, do not create an arbitrary IP address; 
always follow the guidelines above. For more information on address assignment, 
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, 
Guidelines for Management of IP Address Space. 
3.9  Nailed-Up Connection (PPP) 
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. 
The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is 
disabled. The second is that the Prestige will try to bring up the connection when turned on and whenever 
the connection is down. A nailed-up connection can be very expensive for obvious reasons.  
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a 
constant connection and the cost is of no concern 
3.10 NAT 
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a 
packet, for example, the source address of an outgoing packet, used within one network to a different IP 
address known within another network. 
3.11  Wizard Setup Configuration: ISP Parameters 
The second wizard screen varies depending on what mode and encapsulation type you use. All screens 
shown are with routing mode. Configure the fields and click Next to continue.   
3.11.1 PPPoA 
Select PPPoA from the Encapsulation drop-down list box in the first wizard screen to display the screen as 
shown.
