Chapter 2: Hardware Installation
2.1 Installation Requirements
Before installing the Content Security Gateway, make sure your network meets the following requirements.
- Mechanical Requirements
The Content Security Gateway is to be installed between your Internet connection and local area network.
The Content Security Gateway can be placed on the table or rack. Locate the unit near the power outlet.
- Electrical Requirements
The Content Security Gateway is a power-required device, it means, the Content Security Gateway will not
work until it is powered. If your networked PCs will need to transmit data all the time, please consider use
an UPS (Uninterrupted Power Supply) for your Content Security Gateway. It will prevent you from network
data loss. In some area, installing a surge suppression device may also help to protect your Content
Security Gateway from being damaged by unregulated surge or current to the Content Security Gateway.
- Network Requirements
In order for Content Security Gateway to secure your network traffic, the traffic must pass through Content
Security Gateway at a useful point in a network. In most situations, the Content Security Gateway should
be placed behind the Internet connection device.
2.2 Operation Mode
CS-500 DMZ port supports three operation modes, Disable, NAT and Transparent. In Disable mode, the DMZ
port is not active. In transparent mode, CS-500 works as proxy with forward DMZ packet to WAN and forward
WAN packet to DMZ, the DMZ and WAN side IP addresses are in the same subnet. In NAT mode, DMZ side
user will share one public IP address of WAN port to make Internet connection. Please find the following two
pictures for example.

Content Security Gateway User’s Manual
Chapter 3: Getting Started
3.1 Web Configuration
STEP 1:
Connect both the Administrator’s PC and the LAN port of the Content Security Gateway to a hub or switch.
Make sure there is a link light on the hub/switch for both connections. The Content Security Gateway has an
embedded web server used for management and configuration. Use a web browser to display the
configurations of the Content Security Gateway (such as Internet Explorer 4(or above) or Netscape 4.0(or
above) with full java script support). The default IP address of the Content Security Gateway is 192.168.1.1
with a subnet mask of 255.255.255.0. Therefore, the IP address of the Administrator PC must be in the range
between 192.168.1.2– 192.168.1.254
If the company’s LAN IP Address is not subnet of 192.168.1.0, (i.e. LAN IP Address is 172.16.0.1), then the
Administrator must change his/her PC IP address to be within the same range of the LAN subnet (i.e.
172.16.0.2). Reboot the PC if necessary.
By default, the Content Security Gateway is shipped with its DHCP Server function enabled. This means the
client computers on the LAN network including the Administrator PC can set their TCP/IP settings to
automatically obtain an IP address from the Content Security Gateway.
The following table is a list of private IP addresses. These addresses may not be used as a WAN IP address.
10.0.0.0 ~ 10.255.255.255
172.16.0.0 ~ 172.31.255.255
192.168.0.0 ~ 192.168.255.255
STEP 2:
Once the Administrator PC has an IP address on the same network as the Content Security Gateway, open
up an Internet web browser and type in http://192.168.1.1 in the address bar.
A pop-up screen will appear and prompt for a username and password. A username and password is required
to connect to the Content Security Gateway. Enter the default login username and password of Administrator
(see below).

Software Update: The administrator can update the device’s software with the latest version. Administrators
may visit distributor’s web site to download the latest firmware. Administrators may update the device
firmware to optimize its performance and keep up with the latest fixes for intruding attacks.
Configure:
Setting: The Administrator may use this function to backup Content Security Gateway configurations and
export (save) them to an “Administrator” computer or anywhere on the network; or restore a configuration
file to the device; or restore the Content Security Gateway back to default factory settings. Under Setting, the
Administrator may enable e-mail alert notification. This will alert Administrator(s) automatically whenever the
Content Security Gateway has experienced unauthorized access or a network hit (hacking or flooding). Once
enabled, an IP address of a SMTP (Simple Mail Transfer protocol) Server is required. Up to two e-mail
addresses can be entered for the alert notifications.
Date/Time: This function enables the Content Security Gateway to be synchronized either with an Internet
Server time or with the client computer’s clock.
Multiple Subnet: This function allows local port to set multiple subnet works and connect with the internet
through WAN IP Addresses.
Route Table: Use this function to enable the Administrator to add static routes for the networks when the
dynamic route is not efficient enough.

Content Security Gateway User’s Manual
DHCP: Administrator can configure DHCP (Dynamic Host Configuration Protocol) settings for the LAN (LAN)
network.
Dynamic DNS: The Dynamic DNS (require Dynamic DNS Service) allows you to alias a dynamic IP address
to a static hostname, allowing your device to be more easily accessed by specific name. When this function is
enabled, the IP address in Dynamic DNS Server will be automatically updated with the new IP address
provided by ISP.
Host Table: The Content Security Gateway Administrator may use the Host Table function to make the
Content Security Gateway act as a DNS Server for the LAN and DMZ network. All DNS requests to a specific
Domain Name will be routed to the Content Security Gateway’s IP address. For example, let’s say an
organization has their mail server (i.e., mail.planet.com.tw) in the DMZ network (i.e. 192.168.10.10). The
outside Internet world may access the mail server of the organization easily by its domain name, providing
that the Administrator has set up Virtual Server or Mapped IP settings correctly. However, for the users in the
LAN network, their WAN DNS server will assign them a public IP address for the mail server. So for the LAN
network to access the mail server (mail.planet.com.tw), they would have to go out to the Internet, then come
back through the Content Security Gateway to access the mail server. Essentially, the LAN network is
accessing the mail server by a real public IP address, while the mail server serves their request by a NAT
address and not a real one. This odd situation occurs when there are servers in the DMZ network and they
are bound to real IP addresses. To avoid this, set up Host Table so all the LAN network computers will use the
Content Security Gateway as a DNS server, which acts as the DNS Proxy.
Language: Both Chinese and English are supported in the Content Security Gateway.

4.2.3 DMZ
The Administrator uses the DMZ Interface to set up the DMZ network. The DMZ network consists of server
computers such as FTP, SMTP, and HTTP (web). These server computers are put in the DMZ network so they
can be isolated from the LAN (LAN) network traffic. Broadcast messages from the LAN network will not cross
over to the DMZ network to cause congestions and slow down these servers. This allows the server computers
to work efficiently without any slowdowns.

4.3 Policy Object
The Policy Object is the pre-setting item for Policy editing. The administrator can configure all necessary
items here before he wants to configure Content Security Gateway Policy. The contents include Address,
Service, Schedule, QoS, Authentication, Content Blocking, Virtual server and VPN.
4.3.1 Address
The Content Security Gateway allows the Administrator to set addresses of the LAN network, LAN network
group, WAN network, WAN group, DMZ network and DMZ group.
What is the Address Table?
An IP address in the Address Table can be an address of a computer or a sub network. The Administrator can
assign an easily recognized name to an IP address. Based on the network it belongs to, an IP address can be
an LAN IP address, WAN IP address and DMZ IP address. If the Administrator needs to create a control
policy for packets of different IP addresses, he can first add a new group in the LAN Network Group or the
WAN Network Group and assign those IP addresses into the newly created group. Using group addresses
can greatly simplify the process of building control policies.
- 43 -
Content Security Gateway User’s Manual
How to use Address Table
With easily recognized names of IP addresses and names of address groups shown in the address table, the
Administrator can use these names as the source address or destination address of control policies. The
address table should be built before creating control policies, so that the Administrator can pick the names of
correct IP addresses from the address table when setting up control policies.

4.3.2 Service
In this section, network services are defined and new network services can be added. There are three sub menus under
Service which are: Pre-defined, Custom, and Group. The Administrator can simply follow the instructions below to
define the protocols and port numbers for network communication applications. Users then can connect to servers and
other computers through these available network services.
What is Service?
TCP and UDP protocols support varieties of services, and each service consists of a TCP Port or UDP port number, such
as TELNET(23), SMTP(21), POP3(110),etc. The Content Security Gateway defines two services: pre-defined service
and custom service. The common-use services like TCP and UDP are defined in the pre-defined service and cannot be
modified or removed. In the custom menu, users can define other TCP port and UDP port numbers that are not in the
pre-defined menu according to their needs. When defining custom services, the client port ranges from 1024 to 65535
- 58 -
Content Security Gateway User’s Manual
and the server port ranges from 0 to 1023.
How do I use Service?
The Administrator can add new service group names in the Group option under Service menu, and assign desired
services into that new group. Using service group the Administrator can simplify the processes of setting up control
policies. For example, there are 10 different computers that want to access 5 different services on a server, such as HTTP,
FTP, SMTP, POP3, and TELNET. Without the help of service groups, the Administrator needs to set up 50 (10x5) control
policies, but by applying all 5 services to a single group name in the service field, it takes only one control policy to
achieve the same effect as the 50 control policies.

creating a schedule, the Administrator is allowing the Content Security Gateway policies to be used at those
designated times only. Any activities outside of the scheduled time slot will not follow the Content Security
Gateway policies therefore will likely not be permitted to pass through the Content Security Gateway. The
Administrator can configure the start time and stop time, as well as creating 2 different time periods in a day.
For example, an organization may only want the Content Security Gateway to allow the LAN network users to
access the Internet during work hours. Therefore, the Administrator may create a schedule to allow the
Content Security Gateway to work Monday-Friday, 8AM - 5PM only. During the non-work hours, the Content
Security Gateway will not allow Internet access.

Content Security Gateway User’s Manual
Authentication Port: The port number used for user login page.
Generally, when user want to access WAN network and the authentication (Policy -> Outgoing) is enabled,
the user only need to open a web page and the User Login page will pop up.
But if user does not need to open the web page and also want to access Internet resource such as FTP, then
the user has to send http request with this port number, and CS-500 will send a User Login page for user to
input user name and password.
For example, if the gateway IP address is 192.168.1.1 and authentication port is 82, user have to open a web
browser and input http://192.168.1.1:82 on the address file to have the user login page.
Re-Login if Idle: When the LAN users access to WAN network and do not use for a while, the connection will
be time-out. User has to re-login again. The default time is 30 minutes.

4.3.7 Virtual Server
The Content Security Gateway separates an enterprise’s Intranet and Internet into LAN networks and WAN
networks respectively. Generally, in order to allocate enough IP addresses for all computers, an enterprise
- 84 -
Content Security Gateway User’s Manual
assigns each computer a private IP address, and converts it into a real IP address through Content Security
Gateway’s NAT (Network Address Translation) function. If a server providing service to the WAN networks is
located in the LAN networks, outside users can’t directly connect to the server by using the server’s private IP
address.
The Content Security Gateway’s Virtual Server can solve this problem. A virtual server has set the real IP
address of the Content Security Gateway’s WAN network interface to be the Virtual Server IP. Through the
virtual server feature, the Content Security Gateway translates the virtual server’s IP address into the private
IP address of physical server in the LAN network. When outside users on the Internet request connections to
the virtual server, the request will be forwarded to the private LAN server.
Virtual Server owns another feature known as one-to-many mapping. This is when one virtual server IP
address on the WAN interface can be mapped into 4 LAN network server private IP addresses. This option is
useful for Load Balancing, which causes the virtual server to distribute data packets to each private IP
addresses (which are the real servers). By sending all data packets to all similar servers, this increases the
server’s efficiency, reduces risks of server crashes, and enhances servers’ stability.
How to use Virtual Server and mapped IP
Virtual Server and Mapped IP are part of the IP mapping (also called DMZ, De-Militarization Zone) scheme.
By applying the incoming policies, Virtual Server and IP mapping work similarly. They map real IP addresses
to the physical servers’ private IP addresses (which are opposite to NAT), but there are still some differences:
„
Virtual Server can map one real IP to several LAN physical servers while Mapped IP can
only map one real IP to one LAN physical server (1-to-1 Mapping). The Virtual Servers’ load
balance feature can map a specific service request to different physical servers running the
same services.
„
Virtual Server can only map one real IP to one service/port of the LAN physical servers
while Mapped IP maps one real IP to all the services offered by the physical server.
„
IP mapping and Virtual Server work by binding the IP address of the WAN virtual server to
the private LAN IP address of the physical server that supports the services. Therefore
users from the WAN network can access servers of the LAN network by requesting the
service from the IP address provided by Virtual Server.
4.3.7.1 Mapped IP
Internal private IP addresses are translated through NAT (Network Address Translation). If a server is located
in the LAN network, it has a private IP address, and outside users cannot connect directly to LAN servers’
private IP address. To connect to a LAN network server, outside users have to first connect to a real IP
- 85 -
Content Security Gateway User’s Manual
address of the WAN network, and the real IP is translated to a private IP of the LAN network. Mapped IP and
Virtual Server are the two methods to translate the real IP into private IP. Mapped IP maps IP in one-to-one
fashion; that means, all services of one real WAN IP address is mapped to one private LAN IP address.
Entering the Mapped IP window
Step 1. Click Mapped IP under the Virtual Server menu bar and the Mapped IP configuration window
will appear.

Definition:
WAN IP: WAN IP Address.

4.3.8 VPN
The CS-500 adopts VPN to set up safe and private network service, and combine the remote Authentication
system in order to integrate the remote network and PC of the enterprise. It also provides the remote users a
safe encryption way to have best efficiency and encryption when delivering data. CS-500 provides two kinds
of VPN service and the PPTP client.
IPSec Autokey: The system manager can create a VPN connection using Autokey IKE. Autokey IKE
(Internet Key Exchange) provides a standard method to negotiate keys between two security gateways. It
also can set up IPSec Lifetime and Preshared Key of the CS-500.
PPTP Server: The System Manager can set up VPN-PPTP Server functions at CS-500 in this chapter.
PPTP Client: The System Manager can set up VPN-PPTP Client functions at CS-500 in this chapter.
Tunnel: To define local and remote VPN device with related information, then the Tunnel entry can be
selected in Policy in order to submit the further function to the VPN traffic.
What is New?
CS-500 isolates the Tunnel setting in order to allow Policy rule controlling VPN traffic. So user can filter the
VPN packets with QoS, IDP rule, and record the connection in Traffic Log or Statistic. Hence, to set up a
Virtual Private Network (VPN), you need to configure CS-500 with following setting:
1. Configure IPSec Autokey for the encryption and authentication or PPTP Server/Client setting.
2. Configure Tunnel for the information of local and remote VPN device.
3. Configure Incoming Policy Rule to combine VPN traffic with QoS, IDP and the other function.
4.3.8.1 IPSec Autokey
This chapter describes steps to create a VPN connection using Autokey IKE. Autokey IKE (Internet Key
Exchange) provides a standard method to negotiate keys between two security gateways. For example, with

Content Security Gateway User’s Manual
4.4 Policy
This section provides the Administrator with facilities to sent control policies for packets with different source
IP addresses, source ports, destination IP addresses, and destination ports. Control policies decide whether
packets from different network objects, network services, and applications are able to pass through the
Content Security Gateway.
What is Policy?
The device uses policies to filter packets. The policy settings are: source address, destination address,
services, permission, packet log, packet statistics, and flow alarm. Based on its source addresses, a packet
can be categorized into:
(1)Outgoing: a client is in the LAN networks while a server is in the WAN networks.
(2) Incoming, a client is in the WAN networks, while a server is in the LAN networks.
(3) To DMZ: a client is either in the LAN networks or in the WAN networks while, server is in DMZ.
(4) From DMZ, a client is in DMZ while server is either in the LAN networks or in the WAN networks.
How do I use Policy?
The policy settings are source addresses, destination addresses, services, permission, log, statistics, and
flow alarm. Among them, source addresses, destination addresses and IP mapping addresses have to be
defined in the Address menu in advance. Services can be used directly in setting up policies, if they are in
the Pre-defined Service menu. Custom services need to be defined in the Custom menu before they can be
used in the policy settings.
If the destination address of an incoming policy is a Mapped IP address or a Virtual Server address, then the
address has to be defined in the Virtual Server section instead of the Address section.
Policy Directions:
Step 1.
In Address, set names and addresses of source networks and destination networks.
Step 2.
In Service, set services.
Step 3.
In Virtual Server, set names and addresses of mapped IP or virtual server (only applied to
Incoming policies).
Step 4.
Set control policies in Policy.

network.
