Meanwhile, Instant Messaging (IM) and peer-to-peer (P2P) are the fastest growing communications medium of all time, the spread of IM and P2P has created a network security threats and consumed amount of bandwidth. CS-500 also can prevent employees using varied IM and P2P like MSN, Yahoo Messenger, ICQ, QQ and Skype.

CS-500 not only can filter spam and virus mail, but also is a high performance VPN firewall. The IDP and firewall function can defense hacker and blaster attack from Internet. Moreover, built-in QoS feature can let you configure the traffic per specific protocol more flexibly. The completely function in one device can offers an excellent security solution and the secure environment for the SMB or SOHO users.

1.1 Features

♦ Anti-Spam Filtering: Multiple defense layers (Head Analysis, Text Analysis, Blacklist & Whitelist,

Bayesian Filtering), and Heuristics Analysis to block over 95% spam mail. Customizable notification options and spam mail report are provided for administrator. Varied actions toward spam mail include: Delete, Deliver, and Forward. Built-in auto-training system to rise identify rate of spam mail substantially.

♦ Anti-Virus Protection: Built-in Clam virus scan engine can detect viruses, worms, and other threats

from email transfer. Scan mission-critical content protocols-SMTP, POP in real time as traffic enters the network to provide maximum protection. Customizable notification options and virus mail report are provided for administrator. Varied actions toward spam mail include: Delete, Deliver, and Forward.

♦ Policy-based Firewall: The built-in policy-based firewall prevent many known hacker attack including

SYN attack, ICMP flood, UDP flood, Ping of Death, etc. The access control function allowed only specified WAN or LAN users to use only allowed network services on specified time.

♦ VPN Connectivity: The security gateway support PPTP server/client and IPSec VPN. With DES, 3DES

and AES encryption and SHA-1 / MD5 authentication, the network traffic over public Internet is secured.

♦ Content Filtering: The security gateway can block network connection based on URLs, Scripts (The

Pop-up, Java Applet, cookies and Active X), P2P (eDonkey, Bit Torrent, WinMX and Foxy), Instant

Messaging (MSN, Yahoo Messenger, ICQ, QQ and Skype), Download and Upload.

♦ IDP: CS-500 provides three kinds of the Signature to complete the intrusion detection system, user can

select to configure “Anomaly”, “Pre-defined” and “Custom” according to the current environment’s request.

♦ QoS: You can control the outbound and inbound Upstream/downstream Bandwidth by configuring the

QoS based on the WAN bandwidth.

♦ User Authentication: Web-based authentication allows users to be authenticated by web browser. User

database can be configured on the devices or through external RADIUS server.

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

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).

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.

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 serv er 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 Netw ork 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.

The Content Security Gateway allows the Administrator to configure a schedule for policies to take affect. By

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.

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.

ÍÍ

Definition: WAN IP: WAN IP Address. Map to Virtual IP: The IP address which WAN maps to the virtual network in the server. Configure: To change the setting, click Configure to modify the parameters; click delete to delete the setting.
