Multi-Homing Security Gateway User’s Manual
Chapter 1: Introduction
As Internet become essential for your business, the only way to prevent your Internet connection from failure
is to have more than one connection. PLANET’s Multi-Homing Security Gateways (MH-2K/4K, in the
following section) reduce the risk of potential shutdown if one of the Internet connections should fail. In
addition, they allow you to perform load-balancing by distributing the traffic through two WAN connections.
With embedded DNS server of MH-4000, connections from Internet are given the IP address of two WAN
ports to balance the traffic over the links.
Not only a multi-homing device, PLANET’s MH-2K/4K also provides a complete security solution in a box.
The policy-based firewall, Intrusion detection and prevention, content filtering function and VPN connectivity
with 3DES and AES encryption make it a perfect product for your network security. No more complex
connection and settings for integrating different security products on the network is required.
Bandwidth management function is also supported on MH-2K/4K to offers network administrators an easy
yet powerful means to allocate network resources based on business priorities, and to shape and control
bandwidth usage.
1.1 Features
♦ WAN Backup: MH-2K/4K can monitor the each WAN link status and automatically activate backup links
when a failure is detected. The detection is based on the configurable target Internet addresses.
♦ Outbound Load Balancing: The network sessions are assigned based on the user configurable load
balancing mode, including “Auto”, “Round-Robin”, “By Traffic”, “By Session” and “By Packet”. User can
also configure which IP or TCP/UDP type of traffic use which WAN port to connect.
♦ Inbound Load Balancing with Embedded DNS Server: In order to direct traffic to hosted servers
through two links and provide inbound loading balancing, the MH-4000 provides a built-in DNS server for
the hosted servers.
♦ Policy-based Firewall: The built-in policy-based firewall prevents 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 supports PPTP 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 and WinMX), Instant Messaging
(MSN, Yahoo Messenger, ICQ, QQ and Skype) and Download blocking.
♦ Dynamic Domain Name System (DDNS): The Dynamic DNS service allows you to alias a dynamic IP
address to a static hostname.
♦ Multiple NAT: Multiple NAT allows local port to set multiple subnetworks and connect with the Internet
through different WAN IP Addresses.
- 1 -
Multi-Homing Security Gateway User’s Manual
♦ Server Load Balancing: Up to 4 group virtual servers are supported for server load balancing
♦ Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the DHCP client can get
an IP address from the Internet Server Provider (ISP) automatically. In the LAN site, the DHCP server
can allocate up to 253 client IP addresses and distribute them including IP address, subnet mask as well
as DNS IP address to local computers. It provides an easy way to manage the local IP network.
♦ Web based GUI: supports web based GUI for configuration and management. It also supports multiple
language including English, Traditional Chinese and Simplified Chinese.
♦ Bandwidth Management: Network packets can be classified based on IP address, IP subnet and
TCP/UDP port number and give guarantee and burst bandwidth with three levels of priority.
♦ User Authentication: User database can be configured on the devices, MH-4000 also supports the
authenticated database through external RADIUS, POP3 and LDAP server.

Chapter 2: Hardware Installation
2.1 Installation Requirements
Before installing MH-2K/4K, make sure your network meets the following requirements.
- Mechanical Requirements
MH-2K/4K is installed between your Internet connection and local area network. You can place it on the
table or rack, and locate the unit near the power outlet.
- Electrical Requirements
MH-2K/4K is a power-required device, that means, it will not work until it is powered. If your network PCs
will need to transmit data all the time, please consider use an UPS (Uninterrupted Power Supply) for your
MH-2K/4K. It will prevent you from network data loss. In some area, installing a surge suppression device
may also help to protect your device from being damaged by unregulated surge or current to the
MH-2K/4K.
- Network Requirements
In order for MH-2K/4K to secure your network traffic, the traffic must pass through the device at a useful
point in a network. In most situations, MH-2K/4K should be placed behind the Internet connection device.
2.2 Operation Mode
MH-2K/4K DMZ port supports three operation modes, Disable, NAT and Transparent. In Disable mode, the
DMZ port is not active. In transparent mode, MH-2K/4K 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.
- 5 -
2.2.1 Transparent Mode Connection Example
Multi-Homing Security Gateway User’s Manual
The WAN1 and DMZ side IP addresses are on the same subnet. This application is suitable if you have a
subnet of IP addresses and you do not want to change any IP configuration on the subnet.
2.2.2 NAT Mode Connecting Example
DMZ and WAN1 IP addresses are on the different subnet. This provides higher security level then
transparent mode.

Multi-Homing Security Gateway User’s Manual
Chapter 3: Getting Started
3.1 Web Configuration
STEP 1:
Connect the Administrator’s PC and the LAN port of MH-2K/4K to a hub or switch. Make sure there is a link
light on the hub/switch for both connections. MH-2K/4K has an embedded web server used for management
and configuration. Use a web browser to display the configurations of MH-2K/4K (such as Internet Explorer
4(or above) or Netscape 4.0(or above) with full java script support). The default IP address of MH-2K/4K 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, MH-2K/4K 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 device.
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 Multi-Homing 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 MH-2K/4K. Enter the default login username and password of Administrator (see below).

4.1 System
MH-2K/4K Administration and monitoring configuration is set by the System Administrator. The System
Administrator can add or modify System settings and monitoring mode. The sub Administrators can only read
System settings but not modify them. In System, the System Administrator can:
1. Add and change the sub Administrator’s names and passwords;
2. Back up all MH-2K/4K settings into local files;
3. Set up alerts for Hackers invasion.
“System” is the managing of settings such as the privileges of packets that pass through MH-2K/4K and
monitoring controls. Administrators may manage, monitor, and configure MH-2K/4K settings. All
configurations are “read-only” for all users other than the Administrator; those users are not able to change
any settings for MH-2K/4K.
Admin: Control of user access to MH-2K/4K. He/she can add/remove users and change passwords.

Multi-Homing Security Gateway User’s Manual
Setting: The Administrator may use this function to backup MH-2K/4K configurations and export (save) them
to an “Administrator” computer or anywhere on the network; or restore a configuration file to the device; or
restore MH-2K/4K back to default factory settings. Under Setting, the Administrator may enable e-mail alert
notification. This will alert Administrator(s) automatically whenever MH-2K/4K 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 MH-2K/4K 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 different WAN 1 IP Addresses.
Hacker Alert: When abnormal conditions occur, MH-2K/4K will send an e-mail alert to notify the Administrator,
and also display warning messages in the Event window of Alarm.
Blaster Alert: This function is to protect your network from blaster worm. When abnormal network access on
RPC port occur, MH-2K/4K will block the access on specified time, send an e-mail alert or SNMP trap to notify
the Administrator, and also display warning messages in the Event window of Alarm.
Route Table: Use this function to enable the Administrator to add static routes for the networks when the
dynamic route is not efficient enough.
DHCP: Administrator can configure DHCP (Dynamic Host Configuration Protocol) settings for the LAN (LAN)
network.
Host Table: MH-2K/4K Administrator may use the Host Table function to make the device act as a DNS
Server for the LAN and DMZ network. All DNS requests to a specific Domain Name will be routed to
MH-2K/4K’s IP address. For example, 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 MH-2K/4K 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 MH-2K/4K as a DNS server, which acts as the DNS Proxy.

Multi-Homing Security Gateway User’s Manual
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.
SNMP (MH-4000 only): Provide the System Administrator enabling SNMP Trap Alert Notification for sending
email to the setting SNMP Trap receiver IP address when the network is disconnected/ connected and being
attacked by hackers or when emergency conditions occur.
Language: Both Chinese and English are supported in MH-2K/4K.
Permitted IP: Enables the Administrator to authorize specific internal/external IP address(es) for Managing
Gateway.

These attacks will prevent valid users from connecting to the servers. After enabling this
function, the System Administrator can enter the number of SYN packets per second that is
- 29 -
Multi-Homing Security Gateway User’s Manual
allowed to enter MH-2K/4K. Once the SYN packets exceed this limit, the activity will be
logged in Alarm and an email alert is sent to the Administrator. The default SYN flood
threshold is set to 200 Pkts/Sec .
Detect ICMP Flood: Select this option to detect ICMP flood attacks. When hackers
continuously send PING packets to all the machines of the LAN networks or to the
MH-2K/4K, your network is experiencing an ICMP flood attack. This can cause traffic
congestion on the network and slows the network down. After enabling this function, the
System Administrator can enter the number of ICMP packets per second that is allowed to
enter the network or MH-2K/4K. Once the ICMP packets exceed this limit, the activity will be
logged in Alarm and an email alert is sent to the Administrator. The default ICMP flood
threshold is set to 1000 Pkts/Sec.
Detect UDP Flood: Select this option to detect UDP flood attacks. A UDP flood attack is
similar to an ICMP flood attack. After enabling this function, the System Administrator can
enter the number of UDP packets per second that is allow to enter the network MH-2K/4K.
Once the UDP packets exceed this limit, the activity will be logged in Alarm and an email
alert is sent to the Administrator. The default UDP flood threshold is set to 1000 Pkts/Sec .
Detect Ping of Death Attack: Select this option to detect the attacks of tremendous trash
data in PING packets that hackers send to cause System malfunction. This attack can cause
network speed to slow down, or even make it necessary to restart the computer to get a
normal operation.
Detect Tear Drop Attack: Select this option to detect tear drop attacks. These are packets
that are segmented to small packets with negative length. Some Systems treat the negative
value as a very large number, and copy enormous data into the System to cause System
damage, such as a shut down or a restart.
Detect IP Sp oofing Attack: Select this option to detect spoof attacks. Hackers disguise
themselves as trusted users of the network in Spoof attacks. They use a fake identity to try
to pass through MH-2K/4K System and invade the network.
Filter IP Source Route O ption: Each IP packet can carry an optional field that specifies the
replying address that can be different from the source address specified in packet’s header.
Hackers can use this address field on disguised packets to invade LAN networks and send
LAN networks’ data back to them.
Detect Port Scan Attack: Select this option to detect the port scans hackers use to
continuously scan networks on the Internet to detect computers and vulnerable ports that
are opened by those computers.
Detect Land Attack: Some Systems may shut down when receiving packets with the same
source and destination addresses, the same source port and destination port, and when
SYN on the TCP header is marked.

4.1.10 Host Table
The Multi-Homing Security Gateway’s Administrator may use the Host Table function to make the MH-2K/4K
act as a DNS Server for the LAN and DMZ network. All DNS requests to a specific Domain Name will be
routed to MH-2K/4K’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 MH-2K/4K 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 MH-2K/4K as a DNS server, which
acts as the DNS Proxy.

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 Address
MH-2K/4K allows the Administrator to set addresses of the LAN network, LAN network group, WAN network,
WAN group, DMZ network and DMZ group. These settings are to be used for policy editing.
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
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.
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.

4.4 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. MH-2K/4K 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 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.
