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.

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 3-30:

Figure 3-30 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.

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).

.

To add a new rule, enter the following data on the

Port Triggering

screen.

1.

Click the

Add New button

. (pop-up Figure 3-31)

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

)

Note:

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

Each rule allowed to be used only by one host on LAN synchronously. The trigger connection of

other hosts on LAN will be refused.

Incoming Port Range cannot overlap each other.

3.7.3

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 5-29:

Figure 3-32 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

)

Note:

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

3.7.4

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 3-33:
