L2TP
Specify WAN IP Address
Configure a static IP address. The IP address
could be one issued by an L2TP server.
Subnet Mask
Input the subnet mask of the static IP address.
Default Gateway
Input the IP address of the L2TP server.
Username
Input the username of the L2TP client.
Password
Input the password of the L2TP client.
Connect on Demand
Enables auto-dialing for a dial connection. When
the client port tries to connect to the Internet,
the device will automatically connect with the
L2TPserver. When the network has been idle
for a period of time, the system will break the
connection automatically. (The default time for
automatic connection break is five minutes).
Keep Alive
Enables
the
dial
connection
to
redial
automatically
when
disconnected.
Set
the
redialing time (default is 30 seconds).
MTU
Choose Auto or Manual. Default setting is Auto.
The default manual setting value is 1500 bytes. A
different value could be set in a different network
environment (e.g., ADSL PPPoE MTU: 1492).
Transparent Bridge:
The feature will come in handy in when a company wants to add a firewall or
dual-WAN device without changing the IP addresses of the computers in its
intranet. This function will enable users to integrate existing networks without
changing the original structure. Select the Transparent Bridge mode for the
WAN connection mode. In this way, users will be able to connect normally to
the Internet while keeping the original IP addresses in the intranet.
If there are two WANs configured, users still can select Transparent Bridge
mode for WAN connection mode, and load balancing will still function as usual.
SpecifyWANIPAddress:
Input one of the static IP addresses issued by ISP.
SubnetMask:
Input the subnet mask of the static IP addresses
issued by your ISP:
255.255.255.248 if your ISP
issues six usable addresses, and 255.255.255.240 if
your ISP issues 14 useable addresses.
DefaultGateway:
Input the default gateway of the static IP address
issued by your ISP. For ADSL users, it is usually an
ATU-R IP address.
DNSServer:
Input the DNS IP address set by your ISP. At least
one IP group should be input. The maximum
acceptable is two IP groups.
InternalLANIPRange:
Input the available IP range issued by your ISP.
If your ISP issued two discontinuous IP address
ranges, users can input them into Internal LAN IP
Range 1 and Internal LAN IP Range 2, respectively.
MTU
(MaximumTransmission
Unit):
Choose “Auto” or “Manual”. Default is “Auto.” The
default value is 1500. Different value could be
set in different network environment (e.g., ADSL
PPPoE MTU: 1492).

DMZ Setting
For some network environments, an independent configurable DMZ port
may be required to set up externally connected servers such as WEB and Mail
servers. Therefore, the device supports a set of independent configurable DMZ
ports for users to set up connections for servers with real IP addresses. The DMZ
ports act as bridges between the Internet and LANs.
Check Enable DMZ box and click the edit icon to configure DMZ port.
The DMZ configuration can be classified by subnet and range.
Subnet:
If the DMZ and WAN are located in different subnets:
If the ISP issued useable public IP addresses: 220.243.230.1-14 with Mask
255.255.255.240, users have to separate the 14 IP addresses into two groups:
220.243.230.1-6 with Mask 255.255.255.248, and 220.243.230.9-14 with Mask
255.255.255.248 and then set the device and the gateway in the same group
with the other group in the DMZ.
Range:
If the DMZ and WAN are within same subnet:
IP Range:
Input the IP range located at the DMZ port.

Setting Password
Use the Configuration > Setup > Password page to change the administrator
username and password. It is strongly recommended to change the default
username and password (admin/admin).
CAUTION
If the password is forgotten, reset the router to factory default settings.
All the configurations of the router will disappear.
NOTE:
Remember to click Save before leaving the page. You can also click Cancel
to leave without any change.
NOTE:
If you want to enable remote access on the Firewall > General setting,
changing your password is necessary.
Old Password:
Enter the old password. The default
password is admin.
New Username
:
Enter a new username. To keep the
existing username, leave this field blank.
Confirm New Username:
Re-enter the new username.
New Password:
Enter a new password for the router.
Alphanumeric characters and symbols
are allowed, but no spaces.
Confirm New Password:
Re-enter the new password.
Minimum
Password Complexity
:
Check the box to enable box if you want
to enforce password complexity and
enable the Password Strength Meter.
This option is enabled by default and is
recommended.
NOTE:
When Minimum Password Complexity is enabled, the password must meet
the requirements listed below.
•
At least 8 characters.
•
The password cannot be the same as Username.
•
The password cannot be the same as the current password
•
Must contain characters from at least 3 of the following 4 categories:
uppercase letters, lowercase letters, numbers, and special characters
available on a standard keyboard.
Password Strength Meter:
When
enabling
Minimum
Password
Complexity, the Password Strength Meter
appears
and
indicates
the
password
strength.
Red means you have to reset the password.
Yellow means the password is acceptable.
Green means the password
is strong.
Password
Aging Enforcement:
Choose Disable to make the password
permanent. Choose Change the password
after if you want the password to expire
after the specified period. Check Change
the password after and input the specified
number of Days.
Time
Go to
Configuration > Setup > Time
page to configure the system time. The
exact time of event occurrences will be recorded in the System Log, as will the
time of closing or opening of access for Internet resources. You can select the
NTP Server synchronization function or set up a time manually.

Set the local time using Network Time Protocol (NTP) automatically:
Time Zone
Select your location from the pull-down time zone list to
show correct local time.
Daylight Saving
If there is
Daylight Saving Time
in your area, click
Enabled and enter start date and end day of the period.
NTP Server
Input NTP server IP address.
Set the local time manually:
Date:
Input date as yyyy.mm.dd, i.e., 2013.9.30.
Time:
Input current time as hh:mm:ss, i.e., 08:50:00.
DMZ Host
When the NAT mode is activated, users may need to use applications
that do not support virtual IP addresses, such as network games or video
conferencing. We recommend that users map the device actual WAN IP
addresses directly to the intranet virtual IP addresses. Setting up a DMZ host
will allow one host in the LAN to be exposed to the Internet to use services
such as Internet gaming and video conferencing. Access to the DMZ host
from the Internet can be restricted by using firewall access rules. Use the
Configuration > Setup > DMZ Host page.
Enter the LAN IP address of the server that you want to use as a DMZ host.

Port Forwarding and Port Triggering
You can set up a port forwarding virtual host to allow public access to servers
connected to the LAN ports. Port Forwarding opens a specified port or a port
range for a service, such as FTP, WWW, and mail, etc. Port Triggering opens a
port range for services that use alternate ports to communicate between the
server and LAN host. Use the Configuration > Setup > Forwarding page to
configure.

Port Range Forwarding
Port forwarding can be used to set up public services on your network. When
users from the Internet make certain requests to your network, the router
can forward those requests to computers that are equipped to handle the
requests. If, for example, you set the port number 80 (HTTP) to be forwarded
to IP address 192.168.1.2, then all HTTP requests from outside users will be
forwarded to 192.168.1.2.
To set up other services input the server TCP or UDP port number and the
virtual host IP addresses.
Service
Select the service. You can also add a new service from
Service Management.
IP Address
Input the LAN IP address of the virtual host.
Interface
Select the WAN port. (Dual WAN router only)
Add to list
