Maximum Idle Time:

The amount of time of inactivity before disconnecting

your PPPoE session. Enter a Maximum Idle Time (in minutes) to define a

maximum period of time for which the Internet connection is maintained

HOME > LAN

LAN is short for Local Area Network. This is considered your internal

network. These are the IP settings of the LAN interface for the DI-

604

. These

settings may be referred to as Private settings. You may change the LAN IP

address if needed. The LAN IP address is private to your internal network

and cannot be seen on the Internet.

LAN IP Address:

The IP address of the LAN interface. The default IP

address is 192.168.0.1.

DHCP Server:

Choose

Enable

or

Disable

The range of the IP Address Pool:

Whenever there is a request, the DHCP

server will automatically allocate an unused IP Address from the

IP Address

Pool

to the requesting computer.

You must specify the starting and ending

address of the IP Address pool.

Domain Name:

This field is optional. Enter in the your local domain name.

DHCP stands for Dynamic Host Control Protocol. The DI-604 has a built-in DHCP server. The DHCP

Server will automatically assign an IP address to the computers on the LAN/private network. Be sure

to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address

Automatically.”

When you turn your computers on, they will automatically load the proper TCP/IP

settings provided by the DI-604. The DHCP Server will automatically allocate an unused IP address

from the IP address pool to the requesting computer. You must specify the starting and ending

address of the IP address pool.

ADVANCED > VIRTUAL SERVER

The firewall filters out unrecognized packets to protect your LAN (local area network);

so all computers networked with the DI-604 are invisible to the outside world.

If you

wish, you can make some of them accessible by enabling the

Virtual Server

Mapping.

A virtual server is defined as a

Service Port

, and all requests to this port will be

redirected to the computer specified by the

Server IP

.

For example, if you have an FTP server (port 21) at 192.168.0.1, a Web server (port

80) at 192.168.0.2, and a VPN server at 192.168.0.6, then you need to specify the

following virtual server-mapping table:

Service Port

Server IP

21

192.168.0.1

80

192.168.0.2

192.168.0.6

Some applications require multiple connections, like Internet games, Video

conferencing, Internet telephony and so on. Due to the firewall function,

these applications cannot work without some intervention.

Special

Applications

makes some of these applications work with the DI-604. If

Special Applications

is still insufficient to allow an application to function

correctly, try the

DMZ Host

in the

Miscellaneous Items

options.

Trigger

: the outbound port number the application issued first.

Incoming Ports

: when the trigger packet is detected, the inbound packets to

the specified port numbers are allowed to pass the firewall.

The DI-604 provides some predefined settings in the gray pad on the bottom

of the web page. Select your application in the

Note! At any time, only one PC can use each Special Application tunnel.
