5.7 DHCP
Figure 5-26
The DHCP menu
There are three submenus under the DHCP menu (shown in
Figure 5-26
):
DHCP Settings
,
DHCP Clients List
and
Address Reservation.
Click any of them, and you will be able to
configure the corresponding function.
5.7.1
DHCP Settings
Choose menu “
DHCP
→
DHCP Settings
”, and then you can configure the DHCP Server on the
page (shown in Figure 5-27).The Router is set up by default as a DHCP (Dynamic Host
Configuration Protocol) server, which provides the TCP/IP configuration for all the PC(s) that
are connected to the Router on the LAN.
Figure 5-27
DHCP Settings
DHCP Server - Enable
or
Disable
the DHCP server. If you disable the Server, you must
have another DHCP server within your network or else you must configure the computer
manually.
Start IP Address -
Specify an IP address for the DHCP Server to start with when
assigning IP addresses. 192.168.0.100 is the default start address.
End IP Address -
Specify an IP address for the DHCP Server to end with when assigning
IP addresses. 192.168.0.199 is the default end address.

Address Lease Time -
The
Address Lease Time
is the amount of time a network user
will be allowed connection to the Router with their current dynamic IP Address. Enter the
amount of time in minutes and the user will be "leased" this dynamic IP Address. After the
time is up, the user will be automatically assigned a new dynamic IP address. The range
of the time is 1 ~ 2880 minutes. The default value is 120 minutes.
Default Gateway -
(Optional) Suggest to input the IP address of the LAN port of the
Router, default value is 192.168.0.254.
Default Domain -
(Optional) Input the domain name of your network.
Primary DNS -
(Optional) Input the DNS IP address provided by your ISP. Or consult your
ISP.
Secondary DNS -
(Optional) Input the IP address of another DNS server if your ISP
provides two DNS servers.
Note:
To use the DHCP server function of the Router, you must configure all computers on the LAN as
"Obtain an IP address automatically" mode.
5.7.2
DHCP Clients List
Choose menu “
DHCP
→
DHCP Clients List
”, and then you can view the information about the
clients attached to the Router in the next screen (shown in Figure 5-28
)
.
Figure 5-28
DHCP Clients List
ID -
The index of the DHCP Client.
Client Name
-
The name of the DHCP client.
MAC Address
-
The MAC address of the DHCP client.
Assigned IP
-
The IP address that the Router has allocated to the DHCP client.
Lease Time
-
The time of the DHCP client leased. After the dynamic IP address has
expired, a new dynamic IP address will be automatically assigned to the user.
You cannot change any of the values on this page. To update this page and to show the
current attached devices, click the

Address Reservation
Choose menu “
DHCP
→
Address Reservation
”, and then you can view and add a reserved
address for clients via the next screen (shown in Figure 5-29). When you specify a reserved IP
address for a PC on the LAN, that PC will always receive the same IP address each time when
it accesses the DHCP server. Reserved IP addresses should be assigned to the servers that
require permanent IP settings.
Figure 5-29

5.8 Forwarding
Figure 5-31 The Forwarding menu
There are four submenus under the Forwarding menu (shown in Figure 5-31):
Virtual Servers
,
Port Triggering
,
DMZ
and
UPnP
. Click any of them, and you will be able to configure the
corresponding function.
5.8.1
Virtual Servers
Choose menu “
Forwarding
→
Virtual Servers
”, and then you can view and add virtual servers
in the next screen (shown in
Figure 5-32
). Virtual servers can be used for setting up public
services on your LAN. A virtual server is defined as a service port, and all requests from
Internet to this service port will be redirected to the computer specified by the server IP. Any
PC that was used for a virtual server must have a static or reserved IP address because its IP
address may change when using the DHCP function.
Figure 5-32
Virtual Servers
Service Port
- The numbers of External Service Ports. You can enter a service port or a
range of service ports (the format is XXX – YYY; XXX is the Start port and YYY is the End
port).

3.
Enter the IP address of the computer running the service application in the
IP Address
field.
