5.6  Configuring IP Alias
IP Alias allows you to partition a physical network into different logical networks over the 
same Ethernet interface. The Prestige supports three logical LAN interfaces via its single 
physical Ethernet interface with the Prestige itself as the gateway for each LAN network.
To change your Prestige’s IP Alias settings, click LAN, then the IP Alias tab. The screen 
appears as shown.

IP AddressEnter the IP address of your Prestige in dotted decimal notation. 
IP Subnet MaskYour Prestige will automatically calculate the subnet mask based on the IP 
address that you assign. Unless you are implementing subnetting, use the subnet 
mask computed by the Prestige.
RIP DirectionRIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to 
exchange routing information with other routers. The RIP Direction field controls 
the sending and receiving of RIP packets. Select the RIP direction from Both/In 
Only/Out Only/None. When set to Both or Out Only, the Prestige will broadcast 
its routing table periodically. When set to Both or In Only, it will incorporate the 
RIP information that it receives; when set to None, it will not send any RIP 
packets and will ignore any RIP packets received.
RIP VersionThe RIP 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. Multicasting can reduce the load on non-router machines since they 
generally do not listen to the RIP multicast address and so will not receive the RIP 
packets. However, if one router uses multicasting, then all routers on your 
network must use multicasting, also. By default, RIP direction is set to Both and 
the Version set to RIP-1.

WAN Screens
This chapter describes how to configure WAN settings.
6.1  WAN Overview
See the Wi z a rd  S e t u p chapter for more information on the fields in the WAN screens.
6.2  TCP/IP Priority (Metric)
The metric represents the cost of transmission. A router determines the best route for 
transmission by choosing a path with the lowest cost. RIP routing uses hop count as the 
measurement of cost, with a minimum of 1 for directly connected networks. The number 
must be between 1 and 15; a number greater than 15 means the link is down. The 
smaller the number, the lower the cost.
The metric sets the priority for the Prestige’s routes to the Internet. If the routes have the same 
metric, the Prestige uses the following pre-defined priorities:
1WA N: designated by the ISP or a static route (see the IP Static Route Setup chapter)
2Traffic Redirect (see the Configuring Traffic Redirect section )
For example, if WA N has a metric of 1 and Traffic Redirect has a metric of 2, the WA N 
connection acts as the primary default route. If the WA N route fails to connect to the Internet, 
the Prestige tries Traffic Redirect next.
6.3  Configuring Route
Click WA N to open the Route screen.

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft 
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband 
modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-
up connection using PPPoE.

Telia server logs the Prestige out if the Prestige does not log in periodically. Type

logins.

75Chapter 6 WAN Screens
For the service provider, PPPoE offers an access and authentication method that works with 
existing access control systems (for example Radius). PPPoE provides a login and 
authentication method that the existing Microsoft Dial-Up Networking software can activate, 
and therefore requires no new learning or procedures for Windows users.
One of the benefits of PPPoE is the ability to let you access one of multiple network services, 
a function known as dynamic service selection. This enables the service provider to easily 
create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires 
no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the Prestige (rather than individual computers), the 
computers on the LAN do not need PPPoE software installed, since the Prestige does that part 
of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
The screen shown next is for PPPoE encapsulation.

6.4.3  PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of 
data from a remote client to a private server, creating a Virtual Private Network (VPN) using 
TCP/IP-based networks.
PPTP supports on-demand, multi-protocol and virtual private networking over public 
networks, such as the Internet.
The screen shown next is for PPTP encapsulation.
