WAN (Wide Area Network)
WAN refers to your Wide Area Network connection, i.e. your router’s connection to your ISP
and the Internet. There are two items within the
WAN
section:
ISP
,
DNS
and
ADSL
.
ISP
The factory default is PPPoE. If your ISP uses this access protocol, click
Edit
to input
other parameters as below. If your ISP does not use PPPoE, you can change the default
WAN connection entry by clicking
Change
.
A simpler alternative is to select
Quick Start
from the main menu on the left. Please see
the Quick Start section of the manual for more information.

RFC 1483 Routed Connections
Description:
Your description of this connection.
VPI and VCI:
Enter the information provided by your ISP.
ATM Class:
The Quality of Service for ATM layer.
NAT:
The NAT (Network Address Translation) feature allows multiple users to access the
Internet through a single IP account, sharing the single IP address. If users on your LAN
have public IP addresses and can access the Internet directly, the NAT function can be
disabled.
Encapsulation method:
Select the encapsulation format, the default is LlcBridged. Select
the one provided by your ISP.
DHCP client:
Enable or disable the DHCP client, specify if the Router can get an IP address
from the Internet Service Provider (ISP) automatically or not. Please click
Obtain an IP
address automatically via DHCP client
to enable the DHCP client function or click Specify
an IP address to disable the DHCP client function, and specify the IP address manually. The
setting of this item is specified by your ISP.
RIP:
RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
MTU:
Maximum Transmission Unit. The size of the largest datagram (excluding media-
specific headers) that IP will attempt to send through the interface.

PPPoE Connections
Description:
A user-definable name for this connection.
VPI/VCI:
Enter the information provided by your ISP.
ATM Class:
The Quality of Service for ATM layer.
NAT:
The NAT (Network Address Translation) feature allows multiple users to access the
Internet through a single ISP account, sharing a single IP address. If users on your LAN
have public IP addresses and can access the Internet directly, the NAT function can be
disabled.
Username:
Enter the username provided by your ISP. You can input up to
128
alphanumeric characters (case sensitive). This will usually be in the format of
“username@ispname” instead of simply “username”.
Password:
Enter the password provided by your ISP. You can input up to
128
alphanumeric
characters (case sensitive).
Service Name:
This item is for identification purposes. If it is required, your ISP will provide
you the information. Maximum input is
20
alphanumeric characters.
IP Address:
specify if the Router can get an IP address from the Internet Server Provider
(ISP) automatically or not. Please click Obtain an IP address automatically via DHCP client
to enable the DHCP client function or click Specify an IP address to disable the DHCP client

function, and specify the IP address manually. The setting of this item is specified by your
ISP.
Authentication Protocol:
Default is
Chap(Auto
). Your ISP will advise you whether to use
Chap
or
Pap.
Connection:
~
Always on:
If you want the router to establish a PPPoE session when starting up and to
automatically re-establish the PPPoE session when disconnected by the ISP.
~
Connect to Demand:
If you want to establish a PPPoE session only when there is a
packet requesting access to the Internet (i.e. when a program on your computer attempts to
access the Internet).
Idle Timeout:
Auto-disconnect the broadband firewall gateway when there is no activity on
the line for a predetermined period of time.
~
Detail:
You can define the destination port and packet type (TCP/UDP) without checking
by timer. It allows you to set which outgoing traffic will not trigger and reset the idle timer.
RIP:
RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
MTU:
Maximum Transmission Unit. The size of the largest datagram (excluding media-
specific headers) that IP will attempt to send through the interface.
Advanced Options (PPPoE)
LLC Header:
Selects encapsulation mode, true for using LLC or false for using VC-Mux.
Create Route:
This setting specifies whether a route is added to the system after IPCP
(Internet Protocol Control Protocol) negotiation is completed. If set to
enabled
, a route will be
created which directs packets to the remote end of the PPP link.
Specific Route:
Specifies whether the route created when a PPP link comes up is a specific
or default route. If set to
enabled
, the route created will only apply to packets for the subnet
at the remote end of the PPP link. The address of this subnet is obtained during IPCP
negotiation.
Subnet Mask:
sets the subnet mask used for the local IP interface connected to the PPP
transport. If the value
0.0.0.0
is supplied, the netmask will be calculated from the class of the
IP address obtained during IPCP negotiation.
Route Mask:
Sets the subnet mask used by the route that is created when a PPP link
comes up. If it is set to
0.0.0.0
, the subnet mask is determined by the IP address of the
remote end of the link. The class of the IP address is obtained during IPCP (Internet
Protocol Control Protocol) negotiation.
MRU :
Maximum Receive Unit. This is negotiated during the LCP protocol stage.
Discover Primary / Secondary DNS:
This setting enables/disables whether the
primary/secondary DNS server address is requested from a remote PPP peer using IPCP.
The default setting for this command is
enabled
.

Give DNSto Relay:
Controls whether the PPP Internet Protocol Control Protocol (IPCP) can
request the DNS server IP address for a remote PPP peer. Once IPCP has discovered the
DNS server IP address, it automatically gives the address to the local DNS relay so that a
connection can be established.
Give DNSto Client:
Controls whether the PPP Internet Protocol Control Protocol (IPCP) can
request a DNS server IP address for a remote PPP peer. Once IPCP has discovered the
DNS server IP address, it automatically gives the address to the local DNS client so that a
connection can be established.
Give DNSto DHCP Server:
Similar to the above, but gives the DNS server address to the
DHCP server.
Discover Primary NBNS / Discover Secondary NBNS:
This setting enables/disables
whether the primary/secondary NBNS server address is requested from a remote PPP peer
using IPCP. The default setting for this command is disabled.
Discover Subnet Mask:
Specifies if the subnet mask given by IPCP negotiation process is
to be used.
Give Subnet Mask To DHCP Server:
Enable to change your DHCP Server settings by
using the given information in IPCP negotiation process.
