D-Link NetDefendOS Release Notes
Version: 2.20.03
Platform Compatibility: DFL-210/260/800/860/1600/2500
Hardware Version: A1 (for all models), A2/A3/A4 (for DFL-210/800/1600/2500)
Date: Oct 21, 2008
Important Note:
For DFL-210/260/800/860, both LAN and DMZ ports cannot support to manually configure
interface speed, since IXP4NPE driver only allows auto/auto configuration. If users try to configure
the interface speed manually, the configuration will revert back to auto/auto on Web GUI as a
dummy-proof mechanism in the firmware v2.20.03.
New Features and Enhancements
1. No new features were introduced in the 2.20.03 release.
Problems Resolved
1. Fixed issue with DHCP NAK reception during initial phase of reconfiguration.
2. Fixed issue in OSPF where an LSA could be incorrectly deleted after being re-originated.
3. The interface listings for Marvell Yukon interfaces showed incorrect IRQ values.
It affects in DFL-1600 and DFL-2500 only.
4. The amount of memory used by the IDP engine was too high. The memory consumption has
now been reduced.
5. E-mails from e-mail addresses in the whitelist were blocked if they were classified as spam
messages. Now all e-mails sent from whitelisted addresses will be let through, even if they are
classified as spam.
6. Fixed leap year problem where leap year day was added to January instead of February.

Overview
In this document, the notation Objects->Address book means that in the tree on the left
side of the screen Objects first should be clicked (expanded) and then Address Book.
Most of the examples in this document are adapted for the DFL-800. The same settings can
easily be used for all other models in the series. The only difference is the names of the
interfaces. Since the DFL-1600 and DFL-2500 has more than one lan interface, the lan
interfaces are named lan1, lan2 and lan3 not just lan.
The screenshots in this document is from firmware version 2.04.00. If you are using a later
version of the firmware, the screenshots may not be identical to what you see on your
browser.
To prevent existing settings to interfere with the settings in these guides, reset the
firewall to factory defaults before starting.
How to configure Bandwidth Management
Details for this scenario:
- The WAN1 and WAN2 are using static IP with different ISP xDSL circuits. Both
circuits bandwidth are 1Mbps (in this case, assume 1Mb=1000Kb).
- From LAN to WAN1 HTTP, HTTPS, POP3 and other services connect to
Internet.
- WAN1: For inbound and outbound HTTP and HTTPS, the maximum bandwidth is 500Kb.
- WAN1: For inbound and outbound POP3, the guaranteed bandwidth is 300Kb (maximum
bandwidth is 1000Kb).
- WAN1: For other inbound and outbound service, the maximum bandwidth is 200Kb.
- From LAN to WAN2 SMTP, FTP and VoIP services connect to Internet.
- WAN2: For inbound and outbound SMTP, the guaranteed bandwidth is 500Kb (the
maximum bandwidth is 1000Kb)
- WAN2: For inbound and outbound FTP, the maximum bandwidth is 250Kb.
- WAN2: For inbound and outbound VoIP, the guaranteed bandwidth is 250Kb.

How to configure transparent mode
This scenario shows how a firewall in Transparent Mode can be placed into an
existing network between an Internet access router and LAN, without the need
to reconfigure clients in LAN.
The WAN and LAN interfaces of the firewall will be configured to operate in Transparent
Mode. It is preferred to configure IP addresses on the WAN and LAN interfaces, as this can
improve performance during automatic discovering of hosts.

Require user authentication for web access
This scenario shows how to configure the firewall to require user authentication before
local users can browse the Internet. The user will automatically be redirected to the
login page if not already authenticated. In the end of this guide there is also an
explanation of an alternative set up - how to configure the firewall to use
authentication without the automatic redirection.

Observations
D-Link’s NetDefend Firewall Series packs an
impressive set of features including high-speed
processors, extensive signature databases,
and the power to handle up to a million
concurrent sessions. Enclosed in an industrial
chassis, these firewalls include multiple
user-configurable interfaces, including highspeed
Gigabit ports for flexible, scalable and
bottleneck-free network deployment.
NetDefend makes use of component-based
signatures3 which are built to recognize
and protect against all varieties of known
and unknown attacks. The IPS system can
address all critical aspects of an attack or
potential attack including the payload, NO P
sled, infection, and any exploits. The IPS
database includes attack information and data
from a global attack sensor-grid and exploits
collected from public sites such as the National
Vulnerability Database and Bugtrax.
The D-Link constantly updates its Auto-
Signature Sensor System in order to deliver
high-quality, optimized, IPS signatures. Without
overloading existing security appliances, these
signatures ensure a high ratio of detection
accuracy and the lowest ratio of false positives3.
D-Link NetDefend firewalls can be remotely
managed via a web-based interface or through
a dedicated VPN connection. They include
flexible features to monitor and maintain a
healthy and secure network, such as e-mail
alerts, system log and real-time statistics.
To minimize the impact of any event on an
entire network, D-Link NetDefend firewalls
include a special feature called ZoneDefense
- a mechanism that operates seamlessly with
D-Link xStack switches to perform proactive
network security. ZoneDefense automatically
quarantines infected computers and prevents
them from flooding the network with malicious
traffic.

WAN Failover
What is WAN Failover?
There are two WAN ports on this firewall.
You can use WAN Failover if you need redundancy to your Internet connection or
any other network.
How does is work?
You need to assign one WAN connection as the primary, which will route all traffic
when both links works.
If WAN1 connection drops, all traffic will be re-routed through the WAN2 port.
If WAN2 connection drops, all traffic will be re-routed through the WAN1 port.
The methods this firewall uses to detect a dropping connection are
- If link goes down (e.g. ethernet cable unplugged or gateway power failure)
- ARP Lookup
Setup
This example is a DFL-800 with two NAT routers, DSL-504T setup on two different
ADSL lines. It can be implemented on DFL-1600 and DFL-2500 as well, with various
different WAN connections.
We assume the routers are setup for Internet and that DHCP is enabled.
We assign WAN1 to be the primary connection; WAN2 should only be used if
WAN1 connection dropped.
Customize
Please note that the WAN ports can be setup as Static or PPPoE instead.
You can still use these setup instructions, after you setup your WAN ports for you
specific connections.

How to configure DNS Relay
This example describes about firewalls support to relay DNS query packets from LAN to
Internet for domain name resolving. All DFL firewalls (DFL-210/800/1600/2500) support
this feature from firmware v2.04 and later.
Note: About this feature, it performs relay/forward DNS packets only since D-Link DFL
firewalls don’t built-in DNS server in system kernel. Therefore, it can not instead of real
DNS server to provide domain name resolving and related functionality.
Details:
- LAN IP on firewall: 192.168.1.1 (with the function of DNS relay)
- Lannet on firewall: 192.168.1.0/24
- DNS Server on Internet: 12.0.0.1
1. Addresses
Go to Objects -> Address book -> InterfaceAddresses
Create an IP Address called dns_server with address 12.0.0.1
Click Ok.
2. Create IP Rules to redirect DNS packets to Internet
Go to Rules -> IP Rules
Create a new IP Rule with SAT action.

How to Configure VLAN
This example requires a DFL-1600 or 2500 to be fully implemented. Most settings can
however also be used on a DFL-210 or DFL-800.
Two tag based VLANs will be created on lan3, that connect to switch port with VLAN tag.
Details:
- From lan1, lan2 and lan3: HTTP, HTTPS and DNS connect to Internet via wan2.
- All internal nets can also access the Mail server in dmz.
- Only VLAN2 can access the FTP server in dmz.
1. Addresses
Go to Objects -> Address book -> InterfaceAddresses
Make sure the configured addresses match the following list, and add the objects that not
already exist. To add new objects, select IP address from the add dropdown, enter name and
address and click ok.
2. Ethernet interfaces
Go to Interfaces -> Ethernet.
Edit the wan1 interface to use the following settings.

How to configure WAN loading sharing and failover for two ISPs
using policy based routing
Details for this scenario:
- WAN1 is using dynamic IP with PPPoE
- WAN2 is using a static IP
- From LAN to WAN direction on WAN1 interface, HTTP, HTTPS and FTP services are
allowed to connect to Internet.
- From LAN to WAN direction on WAN2 interface, SMTP, POP3 and Ping services are
allowed to connect to Internet.
WAN1 and WAN2 interface serve for different Internet services at the same time;
meanwhile if any WAN circuit fails, all services will be redirected to the other WAN
interface. When the failed circuit returns to normal, these services will come back to
original WAN circuit.

This guide shows how to configure tunnels between three firewalls. First create
one tunnel from firewall A to firewall B and then a second tunnel from firewall A
to firewall C. Users behind firewall B should be able to reach resources behind
firewall C (and the other way around).

In this document, the notation Objects->Address book means that in the tree on the left
side of the screen Objects first should be clicked (expanded) and then Address Book.
Most of the examples in this document are adapted for the DFL-800. The same settings can
easily be used for all other models in the series. The only difference is the names of the
interfaces. Since the DFL-1600 and DFL-2500 has more than one lan interface, the lan
interfaces are named lan1, lan2 and lan3 not just lan.
The screenshots in this document is from firmware version 2.04.00. If you are using a later
version of the firmware, the screenshots may not be identical to what you see on your
browser.
To prevent existing settings to interfere with the settings in these guides, reset the
firewall to factory defaults before starting.

Click on the newly created folder and create a new rule by clicking on the 'Add' button and selecting
'IP Rule'.
On the 'General' tab, enter a name of your choice into the 'Name' field.
Select 'SAT' from the 'Action' drop down menu.
Select 'SMTP-IN' from the 'Service' drop down menu.
Change the 'Schedule' option as needed (Selecting 'None' will ensure this rule is always applicable)
Under the 'Address Filter' section select the following options as in the screen shot below:
Source Interface: WAN 1
Source Network: all-nets
Destination Interface: core
Destination Network: wan1_ip (the address of the DFL-800's WAN interface)
Click on the 'SAT' tab.
Select 'Destination IP Address'
In the 'New IP Address:' box enter the name of your SMTP-server
(this should have been created previously in the 'Address Book' under the 'Objects' menu)
Click on 'OK'
Create a new rule by clicking on the 'Add' button and selecting 'IP Rule'.
On the 'General' tab, enter a name of your choice into the 'Name' field.
Select 'Allow' from the 'Action' drop down menu.
Select 'SMTP-IN' from the 'Service' drop down menu.

How to Configure ZoneDefense for D-Link switch model DES-3226S
This example will show how to configure the firewall to use ZoneDefense.
Details:
The local network contains a D-Link DES-3226S switch. This example shows how to define a Microsoft-DS Threshold (TCP port 445) of 10 connections/second (eg, the work SASSER.A will send out a large amount of TCP SYN on port 445). If the number of connections exceeds this limitation, the firewall will block the specific hosts port on the switch (host 192.168.2.10 in this scenario). The switch port connected to the firewall should be configured to use 192.168.1.250 and the community string MyCompany.

How to configure transparent mode
This scenario shows how a firewall in Transparent Mode can be placed into an
existing network between an Internet access router and LAN, without the need
to reconfigure clients in LAN.
The WAN and LAN interfaces of the firewall will be configured to operate in Transparent
Mode. It is preferred to configure IP addresses on the WAN and LAN interfaces, as this can
improve performance during automatic discovering of hosts.

How to configure VLAN and route failover
This example requires a DFL-1600 or 2500 to be fully implemented. Most settings can
however also be used on a DFL-210 or DFL-800.
Two tag based VLANs will be created on lan3, that connect to switch port with VLAN tag.
Details:
- From lan1, lan2 and lan3: HTTP, HTTPS and DNS connect to Internet via wan2.
- From dmz: inbound and outbound SMTP services connect to Internet via wan1.
- All internal nets can also access the Mail server in dmz.
- Only VLAN2 can access the FTP server in dmz.
- If anyone of the wan interfaces is disconnected, the traffic from that interface will be
redirected to the other wan interface.
1. Addresses
Go to Objects -> Address book -> InterfaceAddresses
Make sure the configured addresses match the following list, and add the objects that not
already exist. To add new objects, select IP address from the add dropdown, enter name
and address and click ok.
2. Ethernet interfaces
Go to Interfaces -> Ethernet.
Edit the wan1 interface to use the following settings.

IDS pattern: 2005_06_03
Pattern number : 660
Date: June 3, 2005
Description :
*Signatures that would always give false-positives have been removed.
Also some really old signatures (from like 1988) for programs that nobody
uses any more where removed. The removal of these old signatures will
increase the performance of the IDS/IDP engine.
* More descriptive log messages have been added to each signature.
The log message will now for example state the probable impact the
attack had.
* Some signatures where modified to cover a large attack surface. This will
result in higher performance of the IDS/IDP engine and the possibility that
signatures will catch new and undiscovered attacks.
* New and more updated attack signatures where added.
