5.8.3 Address Reservation

Selecting

DHCP

>

Address Reservation

will enable you to specify a reserved IP address for a

PC on the LAN, so the PC will always obtain the same IP address each time when it accesses the

AP. Reserved IP addresses should be assigned to servers that require permanent IP settings.

The screen below is used for address reservation (shown in Figure 5-31).

Forwarding

There are four submenus under the Forwarding menu (shown in Figure 5-33):

Virtual Servers

,

Port Triggering

,

DMZ

and

UPnP

. Click any of them, and you will be able to configure the

corresponding function. The detailed explanations for each submenu are provided below.

Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and

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. Port Triggering is used for some applications that cannot work

with a pure NAT router, like Internet games, video conferencing, Internet calling and so on, which

require multiple connections. 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. 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.

Port Triggering

Selecting

Forwarding > Port Triggering

will enable you to set up Port Triggering entries on the

page as shown in Figure 5-36.

Figure 5-36 Port Triggering

Once configured, operation is as follows:

1.

A local host makes an outgoing connection to an external host 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.



Trigger Port

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

"Trigger" this rule.



Trigger Protocol -

The protocol used for Trigger Ports,

TCP

,

UDP

, or

All

(all protocols

supported by the router).



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.



Incoming Protocol -

The protocol used for Incoming Ports Range, TCP , UDP, or ALL (all

protocols supported by the router).



Status -

The status of this entry is either

Enabled

or

Disabled

.

To add a new rule, please take the following steps:

1.

Click the

Add New…

in Port Triggering page. (pop-up Figure 5-37)

2.

Select a common application from the

Commom Applications

drop-list then the port

parameters will be automatically filled in the corresponding field. If the

Common Applicatins

list does not have the application you want, type the port parameters manually.

3.

Select the protocol used for

Trigger Port

and

Incoming Ports

from the corresponding

pull-down list.

4.

Select the

Enable

option in the

Status

pull-down list..

5.

Click the

Save

button to save the new rule.
