VoIP/(802.11g) ADSL2+ Router
Chapter 4: Configuration
Advanced
Configuration options within the
Advanced
section are for users who wish to take advantage of the
more advanced features of the router. Users who do not understand the features should not attempt to
reconfigure their router, unless advised to do so by support staff.
There are four items within the
Advanced
section:
Static Route, Dynamic DNS
,
Check Email, Device
Management, IGMP
and
VLAN Bridge.
Static Route
Click on
Routing Table
and then choose
Create Route
add a routing table.
Destination:
This is the destination subnet IP address.
Netmask:
Subnet mask of the destination IP addresses based on above destination subnet IP.
Gateway:
This is the gateway IP address to which packets are to be forwarded.
Interface:
Select the interface through which packets are to be forwarded.
Cost:
This is the same meaning as Hop. This should usually be left at 1.

Chapter 4: Configuration
Dynamic DNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname,
allowing users whose ISP does not assign them a static IP address to use a domain name. This is
especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect
to you may use your domain name, rather than having to use your dynamic IP address, which
changes from time to time. This dynamic IP address is the WAN IP address of the router, which is
assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS provider using their
website, for example http://www.dyndns.org/
There are more than 5 DDNS services supported.
~
Disable:
Check to disable the Dynamic DNS function.
~
Enable:
Check to enable the Dynamic DNS function. The following fields will be activated
and required:
Dynamic DNS Server:
Select the DDNS service you have established an account with.
Domain Name, Username and Password:
Enter your registered domain name and your
username and password for this service.
Period:
Set the time period between updates, for the Router to exchange information with the
DDNS server. In addition to updating periodically as per your settings, the router will perform an
update when your dynamic IP address changes.
Via WAN Interface:
Decide which WAN interface you want to use for sending DDNS request.

Check Email
This function allows you to have the router check your POP3 mailbox for new Email messages.
The
Mail
LED on your router will light when it detects new messages waiting for download. You
may also view the status of this function using the
Status – Email Checking
section of the web
interface, which also provides details on the number of new messages waiting. See the
Status
section of this manual for more information.
~
Disable:
Check to disable the router’s Email checking function.
~
Enable:
Check to enable the routers Emailing checking function. The following fields will be
activated and required:
Account Name:
Enter the name (login) of the POP3 account you wish to check.. Normally, it is the
text in your email address before the "@" symbol. If you have trouble with it, please contact your
ISP.
Password:
Enter the account’s password.
POP3 Mail Server:
Enter your (POP) mail server name. You Internet Service Provider (ISP) or
network administrator will be able to supply you with this.
Interval:
Enter the value in minutes between periodic mail checks.
Automatically dial-out for checking emails:
When the function is enabled, your ADSL router will
connect to your ISP automatically to check emails if your Internet connection dropped. Please be
careful when using this feature if your ADSL service is charged by time online.

Chapter 4: Configuration
Device Management
The Device Management advanced configuration settings allow you to control your router’s
security options and device monitoring features.
Embedded Web Server
HTTP Port:
This is the port number the router’s embedded web server (for web-based
configuration) will use. The default value is the standard HTTP port, 80. Users may specify an
alternative if, for example, they are running a web server on a PC within their LAN.
Management IP Address:
You may specify an IP address allowed to logon and access the
router’s web server. Setting the IP address to 0.0.0.0 will disable IP address restrictions,
allowing users to login from any IP address.
Expire to auto-logout:
Specify a time frame for the system to auto-logout the user’s
configuration session.
For Example:
User A changes HTTP port number to
100
, specifies their own IP address of
192.168.1.55
, and sets the logout time to be
100
seconds.
The router will only allow User A
access
from
the
IP
address
192.168.1.55
to
logon
to
the
Web
GUI
by
typing:
http://
192.168.1.254:100
in their web browser. After 100 seconds, the device will automatically
logout User A.

Chapter 4: Configuration
Universal Plug and Play (UPnP)
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with
control and data transfer between devices. UPnP offers many advantages for users running
NAT routers through UPnP NAT Traversal, and on supported systems makes tasks such as port
forwarding much easier by letting the application control the required settings, removing the
need for the user to control advanced configuration of their device.
Both the user’s Operating System and the relevant application must support UPnP in addition to
the router. Windows XP and Windows Me natively support UPnP (when the component is
installed), and Windows 98 users may install the Internet Connection Sharing client from
Windows XP in order to support UPnP. Windows 2000 does not support UPnP.
~
Disable:
Check to disable the router’s UPnP functionality.
~
Enable:
Check to enable the router’s UPnP functionality.
UPnP Port:
Its default setting is 2800. It is highly recommended for users to use this port
value. If this value conflicts with other ports already being used you may wish to change the
port.
SNMP Access Control
(Software on a PC within the LAN is required in order to utilize this function) –
Simple Network Management Protocol.
SNMP V1 and V2:
Read Community:
Specify a name to be identified as the Read Community, and an IP address.
This community string will be checked against the string entered in the configuration file. Once
the string name is matched, user obtains this IP address will be able to view the data.
Write Community:
Specify a name to be identified as the Write Community, and an IP address.
This community string will be checked against the string entered in the configuration file. Once
the string name is matched, users from this IP address will be able to view and modify the data.
Trap Community:
Specify a name to be identified as the Trap Community, and an IP address.
This community string will be checked against the string entered in the configuration file. Once
the string name is matched, users from
this IP address will be sent SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access right from identified IP
address. Once the authentication has succeeded, users from this IP address will be able to view
and modify the data.
SNMP Version: SNMPv2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the SNMPv2
security. The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm
for "security", but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote
monitoring.
Traps supported: Cold Start, Authentication Failure.
