LAN is short for Local Area Network. This is considered your internal network. These are the IP set-

tings of the LAN interface for the DI-624S. 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.

DHCP

stands for

Dynamic Host Control Protocol

. The DI-624S 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-624S. 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.

Select

Enabled

or

Disabled.

The

Using the Configuration Menu

Advanced > Virtual Server

The DI-624S can be configured as a virtual server so that remote users accessing Web or FTP

services via the public IP address can be automatically redirected to local servers in the LAN (Local

Area Network).

The DI-624S firewall feature filters out unrecognized packets to protect your LAN network so all

computers networked with the DI-624S are invisible to the outside world. If you wish, you can make

some of the LAN computers accessible from the Internet by enabling

Virtual Server.

Depending on

the requested service, the DI-624S redirects the external service request to the appropriate server

within the LAN network.

The DI-624S is also capable of port-redirection, meaning incoming traffic to a particular port may be

redirected to a different port on the server computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers

List. There are pre-defined virtual services already in the table. You may use them by enabling them

and assigning the server IP to use that particular virtual service.

Enter the name referencing the virtual service.

The server computer in the LAN (Local Area Network) that will be providing the

virtual services.

The protocol used for the virtual service.

The port number of the service used by the Private IP computer.

The port number on the WAN (Wide Area Network) side that will be used to access

the virtual service.

The schedule of time when the virtual service will be enabled. The schedule may

be set to

Always

, which will allow the particular service to always be enabled.

If it is set to

Time

, select the time frame for the service to be enabled. If the

system time is outside of the scheduled time, the service will be disabled.

If you have a Web server that you wanted Internet users to access at all times,

you would need to enable it. Web (HTTP) server is on LAN (Local Area Network)

computer 192.168.0.25. HTTP uses port 80, TCP.

Example #2:

If you have an FTP server that you wanted Internet users to access by WAN port 2100 and only

during the weekends, you would need to enable it as such. FTP server is on LAN computer

192.168.0.30. FTP uses port 21, TCP.

Name: FTP Server

Private IP: 192.168.0.30

Protocol Type: TCP

Private Port: 21

Public Port: 2100

Schedule: From: 01:00AM to 01:00AM, Sat to Sun

Click on this icon to edit the virtual service

Click on this icon to delete the virtual service

All Internet users who want to access this FTP Server must connect to it from port 2100. This

is an example of port redirection and can be useful in cases where there are many of the same

servers on the LAN network.
