Time value (in minutes). This will disconnect the Router after the
WAN connection has been idle for the amount of time specified.
MTU
The Maximum Transmission Unit size may be changed if you want to
optimize efficiency for uploading data through the WAN interface.
The default setting (
1400
bytes) should be suitable for most users.
Some user may want to adjust the setting to optimize performance for
wireless traffic or when low latency is desired (such as with Internet
gaming). It is highly recommended that the user research how
adjusting the MTU may affect network traffic for better or worse.
Connect mode select
Select the desired option: Always on, Manual, or Connect on demand.
Most users will want to choose the default connection setting, Always

unneling (L2TP) method. L2TP
is a VPN protocol that will ensure a direct connection to the server using an authentication process
that guarantees the data originated from the claimed sender and was not damaged or altered in
transit. Once connected to the VPN tunnel, it seems to the user that the client computer is directly
connected to the internal network. To set up your L2TP connection, enter the following data that
was provided to you by your ISP.

HOME - LAN
You can configure the LAN IP address to suit your preference. Many users will find it convenient to
use the default settings together with DHCP service to manage the IP settings for their private
network. The IP address of the Router is the base address used for DHCP. In order to use the Router
for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of
the Router. The IP addresses available in the DHCP IP address pool will change automatically if you
change the IP address of the Router. See the next section for information on DHCP setup.
LAN Settings window
To change the LAN
IP Address
or
Subnet Mask
, type in the desired values and click the
Apply
button. Your web browser should automatically be redirected to the new IP address. You will asked
to login again to the Router’s web manager.
In addition, the Router can be configured to relay DNS from your ISP or another available service to
workstations on your LAN. When
DNS Relay
is
Enabled
, the Router will accept DNS requests from
hosts on the LAN and forward them to the ISP (or alternative) DNS servers. Alternatively, you may
also disable the DNS relay and configure hosts on your LAN to use DNS servers directly. Most users,
who are using the Router for DHCP service on the LAN and are using DNS servers on the ISP’s
network, will leave DNS relay enabled.

HOME - DHCP
The DHCP server is enabled by default for the Router’s Ethernet LAN interface. DHCP service will
supply IP settings to workstations configured to automatically obtain IP settings that are connected
to the Router though the Ethernet port. When the Router is used for DHCP it becomes the default
gateway for DHCP client connected to it. Keep in mind that if you change the IP address of the
Router the range of IP addresses in the pool used for DHCP on the LAN will also be changed. The IP
address pool can be up to 253 IP addresses.
DHCP window
To display this window, click the
DHCP
button in left menu. Any active DHCP Clients appear at the
top of the window in the DHCP Clients List. The IP address and MAC address for active DHCP clients
are displayed in the list.
The two options for DHCP service are as follows:
-
You may use the Router as a DHCP server for your LAN.
-
You can disable DHCP service and manually configure IP settings for workstations.
Follow the instructions below according to which of the above DHCP options you want to use. When
you have configured the DHCP Settings as you want them, click the
Apply
button to commit the new
settings.
