Virtual Servers

Choose menu “

Forwarding

→

Virtual Servers

”, you can view and add virtual servers in the

next screen (shown in Figure 4-38). 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 be changed when using the DHCP function.

Figure 4-38

Virtual Servers



Service Port -

The numbers of External Ports. You can type a service port or a range of

service ports (in XXX – YYY format, XXX is the start port number, YYY is the end port

number).



Internal Port

- The Internal Service Port number of the PC running the service application.

You can leave it blank if the

Internal Port

is the same as the

Service Port

, or enter a

specific port number when

Service Port

is a single one.



IP Address -

The IP Address of the PC providing the service application.



Protocol -

The protocol used for this application, either

TCP

,

UDP

, or

All

(all protocols

supported by the Router).



Status -

The status of this entry either

To setup a virtual server entry:

1.

Click the

button. (pop-up Figure 4-39)

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

IP Address

box.

4.

Select the protocol used for this application, either

TCP

or

UDP

, or

Otherwise there will be a conflict to disable the virtual server.

4.8.2

Port Triggering

Choose menu “

Forwarding

→

Port Triggering

”, you can view and add port triggering in the next

screen (shown in Figure 4-40). Some applications require multiple connections, like Internet

ames, 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.

Port Triggering

Once the Router is configured, the 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.



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, either

TCP

,

UDP

, or

All

(all

protocols supported by the Router).



Incoming Port -

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, either

TCP

or

UDP,

or

ALL

(all protocols supported by the Router).



Status -

The status of this entry either

Enabled

or

Disabled

.

To add a new rule, follow the steps below.

field will be automatically filled. If the

Common

Applications

do not have the application you need, enter the

Trigger Port

and the

Incoming Ports

manually.

3.

Select the protocol used for Trigger Port from the

Trigger Protocol

drop-down list, either

TCP

,

UDP

DMZ

Choose menu

(shown in Figure 4-42).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 be changed when using the DHCP function.
