FTP. A virtual server is defined as a service port, and all requests from the 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. You can set up virtual servers on this page, shown in Figure
4-27:

Figure 4-27 Virtual Servers

¾ Service Port - The numbers of External Ports. You can type a service port or a range of

service ports (the format is XXX – YYY, XXX is the start port, YYY is the end port).

¾ IP Address - The IP Address of the PC providing the service application.

¾ Protocol - The protocol used for this application, either TCP, UDP, or All (all protocols

supported by the router).

¾ Status - The status of this entry either Enabled or Disabled.

To setup a virtual server entry:

1. Click the Add New button. (pop-up Figure 4-28)

2.

Select the

service you want to use from the Common Service Port list. If the Common
Service Port list does not have the service that you want to use, type the number of the
service port or service port range in the Service Port box.

3. Type the IP Address of the computer in the Server IP Address box.

4. Select the protocol used for this application, either TCP or UDP, or All.

5. Select the Enable checkbox to enable the virtual server.

6. Click the Save button.

If you set the virtual server of service port as 80, you must set the Web management port on
Security –> Remote Management page to be any value except 80 such as 8080. Or else there
will be a conflict to disable the virtual server.

4.7.2 Port Triggering

Some applications require multiple connections, like Internet games, video conferencing, Internet
calling and so on. These applications cannot work with a pure NAT router. Port Triggering is
used for some of these applications that can work with an NAT router. You can set up Port
Triggering on this page shown in Figure 4-29:

Figure 4-29 Port Triggering

Once configured, operation is as follows:

1. A local host makes an outgoing connection using a destination port number defined in the
Trigger Port field.

2. The router records this connection, opens the incoming port or ports associated with this
entry in the Port Triggering table, and associates them with the local host.

3. When necessary the external host will be able to connect to the local host using one of the
ports defined in the Incoming Ports field.

¾ Trigger Port - The port for outgoing traffic. An outgoing connection using this port will

"Trigger" this rule.

42

¾ Trigger Protocol - The protocol used for Trigger Ports, either TCP, UDP, or All (all

protocols supported by the router).

¾ Incoming Ports Range - The port or port range used by the remote system when it

responds to the outgoing request. A response using one of these ports will be forwarded to
the PC that triggered this rule. You can input at most 5 groups of ports (or port section).
Every group of ports must be set apart with ",". For example, 2000-2038, 2050-2051, 2085,
3010-3030.

¾ Incoming Protocol - The protocol used for Incoming Ports Range, either TCP or UDP, or

ALL (all protocols supported by the router).

¾ Status - The status of this entry either Enabled or Disabled.

To add a new rule, enter the following data on the Port Triggering screen.

1. Click the Add New button. (pop-up Figure 4-30)

2.

Enter a port number used

by the application when it generates an outgoing request.

3. Select the protocol used for Trigger Port from the pull-down list, either TCP, UDP, or All.

4. Enter the range of port numbers used by the remote system when it responds to the PC's
request.

5. Select the protocol used for Incoming Ports Range from the pull-down list, either TCP or
UDP, or All.

6. Select the Enable checkbox to enable.

7. Click the Save button to save the new rule.

Figure 4-30 Add or Modify a Triggering Entry

43

There are many popular applications in the Popular Application list. You can select it, and the
application will fill in the Trigger Port, incoming Ports Range boxes and select the Enable
checkbox. It has the same effect as adding a new rule.

To modify or delete an existing entry:

1. Click the Modify in the entry you want to modify. If you want to delete the entry, click the
Delete.

2. Modify the information.

3. Click the Save button.

Click the Enable All button to make all entries enabled

Click the Disabled All button to make all entries disabled.

Click the Delete All button to delete all entries.

Note:

)

1. When the trigger connection is released, the according opening ports will be closed.

2. Each rule allowed to be used only by one host on LAN synchronously. The trigger connection
of other hosts on LAN will be refused.

3. Incoming Port Range cannot overlap each other.

4.7.3 DMZ

The DMZ host feature allows one local host to be exposed to the Internet for a special-purpose
service such as Internet gaming or videoconferencing. DMZ host forwards all the ports at the
same time. Any PC whose port is being forwarded must have its DHCP client function disabled
and should have a new static IP Address assigned to it because its IP Address may change when
using the DHCP function. You can set up DMZ host on this page shown in Figure 4-31:

Figure 4-31 DMZ

To assign a computer or server to be a DMZ server:

1. Click the Enable radio button

2. Enter the local host IP Address in the DMZ Host IP Address field

3. Click the Save button.

44

Note: After you set the DMZ host, the firewall related to the host will not work.

)

4.7.4 UPnP

The Universal Plug and Play (UPnP) feature allows the devices, such as Internet computers, to
access the local host resources or devices as needed. UPnP devices can be automatically
discovered by the UPnP service application on the LAN. You can configure UPnP on this page
that shown in Figure 4-32:

Figure 4-32 UPnP Settings

¾ Current UPnP Status - UPnP can be enabled or disabled by clicking the Enable or Disable

button. As allowing this may present a risk to security, this feature is disabled by default.

¾ Current UPnP Settings List - This table displays the current UPnP information.

• App Description – The description provided by the application in the UPnP request

• External Port - External port, which the router opened for the application.

• Protocol – Shows which type of protocol is opened.

• Internal Port - Internal port, which the router opened for local host.

• IP Address - The UPnP device that is currently accessing the router.

• Status - Either Enabled or Disabled, “Enabled” means that port is still active. Otherwise,

the port is inactive.

Click Refresh to update the Current UPnP Settings List.
