2.2 Network setting & Software Installation

To use this product correctly, you have to properly configure the network settings of your
computers and install the attached setup program into your MS Windows platform
(Windows 95/98/NT/2000).

Step 1: Make Correct Network Settings of Your Computer
The default IP address of this product is 192.168.123.254, an d the de fault subn et mask is

255.255.255.0. These addresses can be changed on your need, but the default values
are used in this manual. If the TCP/IP environment of your computer has not yet been
configured, you can refer to Appendix A to configure it.

For example

1. configure IP as 192.168.123.1, subnet mask as 255.255.255.0 and gateway as

192.168.123.254, or more easier,

2. configure your computers to load TCP/IP setting automatically, that is, via DHCP
server of this product.

After installing the TCP/IP communication protocol, you can use the ping command
to check if your computer has successfully connected to this product. The following
example shows the ping procedure for Windows 95 platforms. First, execute the ping
command

ping 192.168.123.254

If the following messages appear:

Pinging 192.168.123.254 with 32 bytes of data:
Reply from 192.168.123.254: bytes=32 time=2ms TTL=64

Then a communication link between your computer and this product has been
successfully established. Otherwise, if you get the following messages,

Pinging 192.168.123.254 with 32 bytes of data:
Request timed out.

There must be something wrong in your installation procedure. You have to check the
following items in sequence:

1. Is the Ethernet cable correctly connected between this product and your
computer?

Tip: The LAN LED of this product and the link LED of network card on your
computer must be lighted.

2. Is the TCP/IP environment of your computers properly configured?

Tip: If the IP address of this product is 192.168.123.254, the IP address of your
computer must be 192.168.123.X and default gateway must be 192.168.123.254.

3.4.4. Forwarding Rules

17

3.5. Forwarding Rules

18

3.5.1. Virtual Server

This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so all
hosts behind this product 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. Virtual Serv er can work with
Scheduling Rules, and give user more flexibility on Access control. For Detail, please
refer to Scheduling Rule.

For example, if you have an FTP server (port 21) at 192.168.123.1, a Web server (port

80) at 192.168.123.2, and a VPN server at 192.168.123.6, then you need to specify the
following virtual server mapping table:

Service Port Server IP Enable

21 192.168.123.1 V
80 192.168.123.2 V

1723 192.168.123.6 V

19

3.5.2. Special AP

Some applications require multiple connections, like Internet games, Video conferencing,
Internet telephony, etc. Because of the firewall function, these applications cannot work
with a pure NAT router. The Special Applications feature allows some of these
applications to work with this product. If the mechanism of Special Applications fails to
make an application work, try setting your computer as the DMZ host instead.

1. Trigger: the outbound port number issued by the application..

2. Incoming Ports : when the trigger packet is detected, the inbound packets sent to
the specified port numbers are allowed to pass through the firewall.

This product provides some predefined settings Select your application and click Copy to
to add the predefined setting to your list.
Note! At any given time, only one PC can use each Special Application tunnel.

20

3.5.3. Miscellaneous Items

IP Address of DMZ Host

DMZ (DeMilitarized Zone) Host is a host without the protection of firewall. It allows a
computer to be exposed to unrestrict ed 2- way communication for Internet games, Video
conferencing, Internet telephony and other special applications.

NOTE: This feature should be used only when needed.

Non-standard FTP port

You have to configure this item if you want to access an FTP server whose port number
is not 21. This setting will be lost after rebooting.

21

3.6. Security Settings

22

3.6.1. Packet Filter

Packet Filter enables you to control what packets are allowed to pass the router.
Outbound filter applies on all outbound packets. However, Inbound filter applies on
packets that destined to Virtual Servers or DMZ host only. You can select one of the two
filtering policies:

1. Allow all to pass except those match the specified rules

2. Deny all to pass except those match the specified rules

You can specify 8 rules for each direction: inbound or outbound. For each rule, you can
define the following:

• Source IP address

• Source port address

• Destination IP address

• Destination port address

• Protocol: TCP or UDP or both.

• Use Rule#

For source or destination IP address, you can define a single IP address (4.3.2.1) or a
range of IP addresses (4.3.2.1-4.3.2.254). An empty implies all IP addresses.
For source or destination port, you can define a single port (80) or a range of ports

23

(1000-1999). Add prefix "T" or "U" to specify TCP or UDP protocol. For example, T80,
U53, U2000-2999. No prefix indicates both TCP and UDP are defined. An empty implies
all port addresses. Packet Filter can work with Scheduling Rules, and give user more
flexibility on Access control. For Detail, please refer to Scheduling Rule.

Each rule can be enabled or disabled individually.
Inbound Filter:
To enable Inbound Packet Filter click the check box next to Enable in the Inbound

Packet Filter field.
Suppose you have SMTP Server (25), POP Server (110), Web Server (80), FTP Server

(21), and News Server (119) defined in Virtual Server or DMZ Host.
Example 1:

(1.2.3.100-1.2.3.149) They are allow to send mail (port 25), receive mail (port 110), and
browse the Internet (port 80)

(1.2.3.10-1.2.3.20) They can do everything (block nothing)
Others are all blocked.

24

Example 2:

(1.2.3.100-1.2.3.119) They can do everything except read net news (port 119) and
transfer files via FTP (port 21)
Others are all allowed.

After Inbound Packet Filter setting is configured, click the save button.
Outbound Filter:

To enable Outbound Packet Filter click the check box next to Enable in the Outbound
Packet Filter field.

25

Example 1:

(192.168.123.100-192.168.123.149) They are allowed to send mail (port 25), receive mail
(port 110), and browse Internet (port 80); port 53 (DNS) is necessary to resolve the
domain name.

(192.168.123.10-192.168.123.20) They can do everything (block nothing)
Others are all blocked.

26

Example 2:

(192.168.123.100-192.168.123.119) They can do everything except read net news (port

119) and transfer files via FTP (port 21)

Others are allowed
After Outbound Packet Filter setting is configured, click the save button.

27

3.6.2. Domain Filter

Domain Filter

Lets you prevent users under this device from accessing specific URLs.

Domain Filter Enable

Privilege IP Addresses Range

Setting a group of hosts and privilege these hosts to access network without restriction.

Domain Suffix

A suffix of URL to be restricted. For example, ".com", "xxx.com".

Action

When someone is accessi ng the URL met the domain-suffix, what kind of action you
want.
Check drop to block the access. Check log to log these access.

Enable

Check to enable each rule.

28

Example:

In this example:

1. URL include “www.msn.com” will be blocked, and the action will be reco rd in log-file.

2. URL include “www.sina.com” will not be blocked, but the ac tion will be record in

log-file.

3. URL include “www.google.com” will be blocked, but the action will not be record in

log-file.

4. IP address X.X.X.1~ X.X.X.20 can access network without restriction.

29

3.6.3. URL Blocking

URL Blocking will block LAN computers to connect to pre-defined websites.

The major difference between “Domain filter” and “URL Blocking” is Domain filter require
user to input suffix (like .com or .org, etc), while URL Blocking require user to input a
keyword only. In other words, Domain filter can block specific website, while URL
Blocking can block hundreds of websites by simply a keyword.

URL Blocking Enable

Checked if you want to enable URL Blocking.

URL

If any part of the Website's URL matches the pre-defined word, the connection will be
blocked.
For example, you can use pre-defined word "sex" to block all websites if their URLs
contain pre-defined word "sex".

Enable

Checked to enable each rule.

30

In this example:

1.URL include “msn” will be blocked, and the actio n will be record in log-file.

2.URL include “sina” will be blocked, but the action will be record in log-file

3.URL include “cnnsi” will not b e blocked, but the action will be record in log-file.

4. URL include “espn” will be blocked , but the action will be record in log-file

31

3.6.4. MAC Address Control

In general, only Intranet user can browse the built-in web pages to perform administration
task. This feature enables you to perform administration task from remote host. If this
feature is enabled, only the specified IP address can perform remote administration. If
the specified IP address is 0.0.0.0, any host can connect to this product to perform
administration task. You can use subnet mask bits "/nn" notation to specified a group of
trusted IP addresses. For example, "10. 1.2. 0/24".

NOTE: When Remote Administration is enabled, the web server port will be shifted to 88.
You can also change web server ports.

3.7.2. System Log

This page support two methods to export system logs to specific destination by means of
syslog(UDP) and SMTP(TCP). The items you have to setup including:

IP Address for Syslogs

Host IP of destination where syslogs will be sent to.
Check Enable to enable this function.

number, the default value is 25.
For example, "mail.your_url.com" or "192.168.1.100:26".

Send E-mail alert to

The recipients who will receive these logs. You can assign more than 1 recipient, using ';'
or ',' to separate these email addresses.

3.7.3. Dynamic DNS

To host your server on a changing IP address, you have to use dynamic domain name
service (DDNS).

So that anyone wishing to reach your host only needs to know the name of it. Dynamic
DNS will map the name of your host to your current IP address, which changes each time
you connect your Internet service provider.

Before you enable Dynamic DNS, you need to register an account on one of these
Dynamic DNS servers that we list in provider field.

To enable Dynamic DNS click the check box next to Enable in the DDNS field.
Next you can enter the appropriate information about your Dynamic DNS Server.
You must define: Provider, Host Name, Username/E-mail, and Password/Key.
You can get this information from the DNS service provider when you register an

account.

37

Example:

After Dynamic DNS setting is configured, click the save button.

3.7.4. SNMP Setting

38

In brief, SNMP, the Simple Network Management Protocol, is a protocol designed to give
a user the capability to remotely manage a computer network by polling and setting
terminal values and monitoring network events.

Enable SNMP

You must check either Local or Remote or both to enable SNMP function. If Local is
checked, this device will response request from LAN. If Remote is checked, this device
will response request from WAN.

Get Community

Setting the community of GetRequest your device will response.

Set Community

Setting the community of SetRequest your device will accept.

3.7.5. Routing Table

39

Routing Tables allow you to determine which physical interface address to use for
outgoing IP data grams. If you have more than one routers and subnets, you will need to
enable routing table to allow packets to find proper routing path and allow different
subnets to communicate with each other.

Routing Table settings are settings used to setup the functions of static.

Static Routing: For static routing, you can specify up to 8 routing rules. You can enter
the destination IP address, subnet mask, gateway, hop for each routing rule, and then
enable or disable the rule by checking or unchecking the Enable checkbox.

Example:

40

Configuration on NAT Router

Destination SubnetMask Gateway Hop Enabled

192.168.1.0 255.255.255.0 192.168.123.216 1 ˇ

192.168.0.0 255.255.255.0 192.168.123.103 1 ˇ

So if, for example, the client3 wanted to send an IP datagram to 192.168.0.2, it would
use the above table to determine that it had to go via 192.168.123.103 (a gateway),
And if it sends Packets to 192.168.1.11 will go via 192.168.123.216
Each rule can be enabled or disabled individually.
After routing table setting is configured, click the save button.

41

3.7.6. Schedule Rule

You can set the schedule time to decide which service will be turned on or off. Select the
“enable” item.
Press “Add New Rule”

You can write a rule name and set which day and what time to schedule from “Start

After configure Rule 1Æ

Schedule Enable

Selected if you want to Enable the Scheduler.
Edit
