The WAN Access Router generates and uses radio frequency energy, and if not installed and used properly-that
is, in strict accordance with the manufacturer’s instructions-may cause interference to radio and television
reception. The WAN Access Router have been tested and found to comply with the limits for a Class A computing device in accordance with specifications in Subpart B of Part 15 of FCC rules, which are designed to
provide reasonable protection from such interference in a commercial installation. However, there is no guarantee that interference will not occur in a particular installation. If The WAN Access Router does cause interference to radio or television reception, which can be determined by disconnecting the unit, the user is
encouraged to try to correct the interference by one or more of the following measures: moving the computing
equipment away from the receiver, re-orienting the receiving antenna and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and receiver are on different branches).

WAN Access Routers Getting Started Guide 2 • Product Overview
Introduction
The WAN Access Router operates as a bridge or a router and has two ports for communication:
• The Ethernet port—Connects to the LAN side of the connection
• The Serial port—Connects to local DTE devices (LR121A and LR122A)
• The T1/E1 port—Connects directly to T1/E1 lines (LR120A)
the router provides all layer 2 and layer 3 protocols required for end-to-end-link communication.
When configuring the WAN Access Router, questions must be answered so the WAN Access Router functions
as desired. For example, when a router or bridge module needs to be activated, some questions would be:
• Is a default gateway required?
• Which encapsulation technique is best for this application: Frame Relay, PPP, or another?
These decisions can be made and implemented more easily if the WAN Access Router’s fundamental architecture
is understood. Also, while configuring The WAN Access Router via a browser using the built-in HTTP server is
very intuitive, an understanding of the architecture is essential when using the command-line interface (CLI)
commands.
The fundamental building blocks comprise a router or bridge, interfaces, and transports. the router and bridge
each have interfaces. A transport provides the path between an interface and an external connection. For example, the Ethernet transport attaches to an Internet Protocol (IP) interface. A transport consists of layer 2 and
everything below it. Creating a transport and attaching it to a bridge or router’s interface enables data to be
bridged or routed. The supported transports are PPPoE, Frame Relay, PPP, and Ethernet.
Configuring an interface and transport for the router or bridge requires naming the interface and transport before
attaching them. When using the built-in HTTP server web browser, this is done automatically. But when configuring The WAN Access Router via CLI commands through the RS-232 control port, it must be done manually.

Introduction
The WAN Access Routers offer various WAN services for the proper transport encapsulation: Ethernet, Frame
Relay, and PPP options. The Ethernet option is PPPoE, bridged only. Frame Relay and PPP can be used in
either bridged or routed applications.
PPP Bridged
Remote site configuration
The WAN Access Routers can be configured as bridges; in this situation the Black Box typically is at the customer premise or branch office and connects to a router or bridge at a service provider location (this can be
another WAN Access Router). This application shows configuration for two Black Box units in bridged mode.
If using a third party router at the Central side, review the router’s configuration for connection to a remote
bridge. (See figure 27.)

LMI configuration
Frame Relay Local Management Interface
The Frame Relay Local Management Interface (LMI) is a mechanism that two separate frame relay systems can
use to communicate the status of the interface. The LMI interface allows dynamic updates on the status of the
DLCI connections and the congestion state of the network. The Black Box implements all three versions of
LMI available within the frame relay network. These are defined in table 4:

WAN Access Routers Getting Started Guide 7 • Security
Introduction
Security provides the ability to setup and enforce security policies. The policies define the types of traffic permitted to pass through a gateway, either inbound, outbound, or both, and from which origins the traffic may
be allowed to enter.
Within the security configuration is a stateful firewall. A stateful firewall utilizes a security mechanism to maintain information concerning the packets it receives. This information is used for deciding dynamically whether
or not a packet may pass through.
Port filters are rules that determine how a packet should be handled. The rules define the protocol type, the
range of source and destination port numbers and an indication whether the packet is allowed or not.
Security triggers are used with applications that require and create separate sessions. The most common example is FTP. An FTP client establishes a connection to a server using port 21, but data transfers are done on a
separate connection or port. The port number, and who makes the connection, can vary depending on the
FTP client. To allow FTP to work without triggers, you would need to set up port filters allowing the correct
port numbers through. This is a significant security risk.
This risk can be avoided by using security triggers. Triggers tell the security mechanism to expect these secondary sessions and how to handle them. Rather than allowing a range of port numbers, triggers handle the situation dynamically, opening the secondary sessions only when appropriate. The triggers work without needing to
understand the application protocol or reading the payload of the packet, although this does happen when
using NAT.
Triggering allows you to set up a trigger for different application protocols that use multiple sessions. The timeout between sessions and whether or not session chaining are allowed are configurable. Session chaining is not
needed for FTP but is for NetMeeting.
Configuring the router
The configuration of security assumes that the WAN Access Router has been configured with a valid IP address
for the Ethernet port so that the user may access the modem via the web page. If the IP address is still the factory default, go to the section in Chapter 3 entitled IP Address Modification.
In this example the WAN transport between the two WAN Access Router/Routers will be PPP (routed).
1. Click on WAN under Services Configuration in the WAN Access Router’s Configuration Menu.
2. Click on Create a new service....
3. Select PPP routed and click on the Continue=> button.
4. For this example, enter PPP Security Firewall in the Description field. (See figure 43.)
5. Click on Create.

Figure 44. IP address of PPP routed WAN service
The next step in configuring the router is to add the default gateway route. The WAN IP address of the routed
PPP WAN service at the CO site is 192.168.101.2, so this will be the gateway IP address on the Black Box.
1. Click on IP routes under Services Configuration in the Configuration Menu.
2. Click on the Create a new Ip route... hyperlink.
3. Enter 192.168.101.2 in the box adjacent to Gateway.
Configuring the router64
WAN Access Routers Getting Started Guide 7 • Security
4. Leave Destination and Netmask both as 0.0.0.0 because this is the gateway default route.
5. Click on the Update button.
6. Seeing the green check mark under Valid indicates the IP addresses of the WAN service and the gateway
are properly configured. (See figure 45.)
Figure 45. Valid gateway route
Configuring the security interfaces
The interfaces and routes have been configured on the WAN Access Router. The Ethernet side of the WAN
Access Router will be configured to be an internal interface and the WAN side is selected to be the external
interface since it is on “public” side of the modem connection.
1. Go to the Security Interface Configuration webpage as follows Configuration Menu > Services Configuration >
Security. (See figure 46.)
Configuring the security interfaces65
Figure 46. Security configuration home page
WAN Access Routers Getting Started Guide 7 • Security
2. Go to the third section (Security Interfaces) on the Security Interface Configuration webpage. Click on the
hyperlink Add interface...
3. Select ip1 beside the Name pull-down menu, and select internal beside the Interface Type pull-down menu.
Click on Create. (See figure 47.)
Figure 47. Define ‘ip1’ interface as Internal
4. Again, click on the hyperlink Add interface... to define the WAN interface as external.
5. Select ppp-0 beside the Name pull-down menu, and select external beside the Interface Type pull-down
menu. Click on Create. (See figure 48.)
Figure 48. Define ‘ppp-0’ interface as External
Configuring security policies
Continue the previous example by defining security policies. We will add only one Firewall policy, called etoi,
signifying an external-to-internal policy between the external and internal interfaces.
1. Go to the last section on the Security Interface Configuration webpage called Policies, Triggers and Intrusion
Detection. Click on the hyperlink Security Policy Configuration... (See figure 49.)
Configuring the security interfaces66
WAN Access Routers Getting Started Guide 7 • Security
Figure 49. Security Policy Configuration hyperlink
2. Click on the hyperlink New Policy... (See figure 50.)
Figure 50. New Policy link to configuration webpage
3. Select the parameters so the policy is defined as follows:
Between interfaces of types: externalinternal
Validators will allow traffic.
Click on Apply.
Deleting a security Policy
To delete a security policy, go to the table of Current Security Policies and click on the Delete button for the
selected security policy.
Figure 51. Deleting a Security Policy
Enabling the Firewall
At this point, both security and the firewall can be enabled and the network is secure. All the interfaces which
have been defined are protected, that is, all traffic has been blocked between the internal (ip1) and external
(ppp-0) interfaces. Only traffic which has validators is allowed to pass through, and, at this moment, there are
no validators.
Enabling the Firewall67
WAN Access Routers Getting Started Guide 7 • Security
1. Return to the Security page.
2. Under Security State select Enabled for Security. Click on Change State.
3. Next select Enabled for Firewall. Click on Change State.
The network is now secure. All the interfaces which have been defined are protected and all traffic is blocked
between different the different interface types. That is, all traffic is blocked between the external and
internal interfaces.
The next section describes how to configure the Firewall for allowing certain types of data transfer to occur
between the PCs on different networks.
Firewall Portfilters
Next, we configure the Firewall to permit certain types of data transfer between the PCs (in general, hosts) on
the different networks. This is done by the implementation of Firewall portfilters. Portfilters are individual
rules that determine what kind of traffic can pass between two interface types.
For the Protocol Number below, the different types are defined as:
This example continues to allow pings over the firewall:
1. From the Configuration Menu, > Configuration > Security > Security Policy Configuration... > Port Filters...
> Add Raw IP Filter
2. Enter 1 (for ICMP) in the Protocol Number field.
3. Set both Inbound and Outbound for Allow. (See figure 52.)
4. Click on Create.
Firewall Portfilters68
WAN Access Routers Getting Started Guide 7 • Security
Figure 52. Defining ICMP port filter for ping
You can now ping between the two networks
Security Triggers
Security triggers are used to allow an application to open a secondary port in order to transport data. The most
common example is FTP. This procedure sets up a trigger on the Firewall to permit an FTP session from PC A
to PC B, but not the reverse.
1. First, create an outbound-only portfilter for FTP and add it to the item0 policy.
2. Following the path given in step 1 for the ping portfilter in the previous section, click on Add TCP Filter.
3. The Port Range is entered as 21 for both Start and End.
4. Set Inbound as Block, but Outbound as Allow. (See figure 53.)
5. Click on Create.
Figure 53. Configuring TCP port filter for FTP
After configuring the FTP portfilter, you can open an ftp session from Remote to Local, however you can issue
ftp commands (e.g., login, cd, etc.). Because the trigger to permit transfer of data via FTP has not been
defined, no data can be transferred. (Data transfer occurs with the commands ls, dir, get, put commands.) The
portfilter allows an ftp control channel but does not allow the use of a secondary data channel for passing data
by ftp.
To enable the FTP data channel, add a trigger to open a secondary channel only when data is being passed.
This minimizes the number of open ports. Each open port is a security risk.
1. From the Configuration Menu, > Configuration > Security > Security Trigger Configuration... >
New Trigger.
Security Triggers69
WAN Access Routers Getting Started Guide 7 • Security
2. Set the parameters as follows (See figure 54.):
– Transport Type = tcp
– Port Number Start = 21
– Port Number End = 21
– Allow Multiple Hosts = Block
– Max Activity Interval = 3000
– Enable Session Chaining = Block
– Enable UDP Session Chaining = Block
– Binary Address Replacement = Block
– Address Translation Type = none
3. Click on Create.

The security feature in the WAN Access Router provides protection from a number of attacks. Some attacks
cause a host to be blacklisted (i.e., no traffic from that host is accepted under any circumstances) for a period of
time. Other attacks are simply logged. The subsequent table is a summary of the attacks detected.

1. To enable IDS, click on Enabled for “Intrusion Detection Enabled” on the “Security Interface Configuration” page. Then click on Change State.
2. Click on Configure Intrusion Detection...
3. You may choose which of the parameters to configure and for which value.
– Use Blacklist: Default = 10 minutes when enabled.
If IDS has detected an intrusion an external host, access to the network is denied for ten minutes.
– Use Victim Protection: Default = Disabled.
Victim Protection. When enabled, Victim Protection protects the victim from an attempted spoofing
attack. Web spoofing allows an attacker to create a ‘shadow’ copy of the world wide web (WWW). All
access to the shadow Web goes through the attacker’s machine, so the attacker can monitor all of the victim’s activities and send false data to or from the victim’s machine. When enabled, packets destined for the
victim host of a spooking style attack are blocked.
– DOS Attack Block Duration:Default = 1800 seconds (30 minutes).
A Denial of Service (DOS) attack is an attempt by an attacker to prevent legitimate users from using a service. If a DOS attack is detected, all suspicious hosts are blocked by the firewall for a set time limit
Sets the duration for blocking all suspicious hosts. The firewall detects when the system is being scanned
by a suspicious host attempting to identify any open ports.
– Maximum TCP Open Handshaking Count:Default = 100
Sets the maximum number of unfinished TCP handshaking sessions per second that are allowed by a firewall before a SYN Flood is detected. SYN Flood is a DOS attack. When establishing normal TCP connections, three packets are exchanged: (1) A SYN (synchronize) packet is sent from the host to the network
server. (2) A SYN/ACK packet is sent from the network server to the host. (3) An Ack (acknowledge)
packet is sent from the host to the network server. If the host sends unreachable source addresses in the
SYN packet, the server sends the SYN/ACK packets to the unreachable addresses and keeps resending
them. This creates a backlog queue of unacknowledged SYN/ACK packets. Once the queue is full, the system will ignore all incoming SYN request and no legitimate TCP connections can be established.
Intrusion Detection System (IDS)71
WAN Access Routers Getting Started Guide 7 • Security
– Once the maximum number of unfinished TCP handshaking sessions is reached, an attempted DOS
attack is detected. The firewall blocks the suspected attacker for the time limit specified in the DOS
Attack Block Duration parameter.
– Maximum Ping Count:Default = 15
Sets the maximum number of pings per second that are allowed by the firewall before an Echo Storm is
detected. Echo Storm is a DOS attack. An attacker sends oversized ICMP datagrams to the system using
the ‘ping’ command. This can cause the system to crash, freeze, or reboot, resulting in denial of service to
legitimate users.
– Maximum ICMP Count:Default = 100
Sets the maximum number of ICMP packets per second that are allowed by the firewall before an ICMP
Flood is detected. An ICMP Flood is a DOS attack. The attacker tries to flood the network with ICMP
packets in order to prevent transmission of legitimate network traffic.

Introduction to NAT
The basic steps for configuring NAT are:
1. Enable NAT between the internal and external interfaces of the firewall.
2. Create global addresses which will be added to the global pool of IP addresses on the WAN interface.
3. Create a reserved mapping between a global IP address and the IP address of an internal PC.
A Global Address Pool is a pool of addresses seen from the outside network. Each external interface creates a
Global Address Pool with a single address—the address assigned to that interface. For outbound sessions, an
address is picked from a pool by hashing the source IP address for a pool index and then hashing again for an
address index. For inbound sessions, it is necessary to create a reserved mapping.
A reserved mapping is used so that NAT knows where to route packets on inbound sessions. The reserved mapping will map a specific global address and port to an inside address and port. Reserved mappings can also be
used so that different inside hosts can share a global address by mapping different ports to different hosts. For
example, Host A is an FTP server and Host B is a web server. By mapping the FTP port to Host A and the
HTTP port to Host B, both insides hosts can share the same global address. Setting the protocol number to
255 (0xFF) means that the mapping will apply to all protocols. Setting the port number to 65535 (0xFFFF) for
TCP or UDP protocols means that the mapping will apply to all port numbers for that protocol.
Some applications embed address and/or port information in the payload of the packet. The most notorious of
these is FTP. For most applications, it is sufficient to create a trigger with address replacement enabled. However there are three applications for which a specific Application Level Gateway is provided: FTP, NetBIOS,
and DNS.
Enabling NAT
The configuration of NAT in this example follows on the preceding configuration completed earlier in
this chapter.
1. Go to the Security Interface Configuration page by clicking on Security under Configuration in the menu.
2. Click on Enable NAT to internal interfaces in the Security Interfaces table. NAT is now enabled between
the internal (LAN) and the external (WAN) interfaces of the firewall.
Global address pool and reserved map
1. Click on Advanced NAT Configuration... on the web page, Security Interface Configuration.
2. Click on the hyperlink Add Global Address Pool... The global IP addresses need to be created and put
into the Global Address Pool.
Introduction to NAT73
WAN Access Routers Getting Started Guide 7 • Security
3. Set the parameters to the following values (See figure 55.):
– Interface Type: internal
– Use Subnet Configuration: Use IP Address Range
– IP Address: 100.100.100.101
– Subnet Mask/IP Address 2: 100.100.100.102
Click on Add Global Address Pool button.
Figure 55. NAT Global Address Pool configuration
4. Next, create a reserved mapping between a global IP address from the global pool and a PC on the side of
the internal interface (ip1). In this example, 10.10.19.11.
5. Click on the hyperlink Add Reserved Mapping...
6. Set the parameters to the following values (See figure 56.):
– Global IP Address: 100.100.100.101
– Internal IP address: 10.10.19.11
– Transport Type: all
– Port Number: 65535(This port number means all port numbers for TCP or UDP protocols will
be mapped.)
7. Click on Add Reserved Mapping.

WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
Introduction
The routers offer a DHCP Server, DHCP Relay capability, and DNS Relay incorporated into the Black Box.
Of the two DHCP features, only one can be enabled at a time-either DHCP server or DHCP relay.
DNS relay can hold two DNS server IP addresses in memory so the DNS relay can forward DNS queries and
responses between the host user and the DNS server.
The DHCP Server will listen for DHCP client requests on a suitable IP interface. Typically this is the Ethernet
interface, named ip1 by default.
NoteThe Ethernet LAN port can be configured as a DHCP client to receive its IP
address from a DHCP server on the Ethernet LAN. If so configured, you
should not enable the Black Box’s DHCP server on the Ethernet interface.
DHCP Relay functions transparently between a a DHCP client and a DHCP server. The DHCP relay appears
as a DHCP server to the DHCP client’s point of view. The relay operates by forwarding all broadcast client
request to known DHCP servers. The DHCP relay listens on all available interfaces. All relay-server communication is unicast. It is important that valid routes are set up to the server and also to the client.
Services and features normally associated with each other
Table 5 on page 78 lists services that are available for configuration if you will be using DHCP Server, DHCP
Relay, or DNS Relay.
If you are configuring a feature listed in the first column (Configured Feature), you can determine which other
features either cannot be, must be, usually, can be, or are rarely used. The “Rarely used” column is listed to be
technically correct, but it is ill advised to use. The three most important columns (other than the first) are:
• Cannot be used
• Must be used
• Usually used
Use the table like this: “The feature in this column [...] with the Configured Feature (in Column 1).”
Introduction77
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
For example:
1. The feature DHCP Relay [column 2] cannot be used with DHCP Server [row 1, column 1].
2. The feature Routed [column 4] usually is used with DHCP Relay [row 2, column 1].

• DHCP Server and DHCP Relay cannot be used simultaneously.
• NAT can be used only if a Routed WAN service is configured.
•1If a DHCP Server were used with a Bridged WAN service, the DHCP server would respond to IP address
requests from both interfaces, that is, the Ethernet and the WAN serial interfaces.
•2When NAT is used together with DHCP Relay, the WAN service must be routed.
•3When DHCP Relay is used with a Bridged WAN service, the DHCP server must be on the same subnet as
the clients and the Black Box.
DHCP Server
Go to the DHCP Server webpage from the Configuration Menu --> Services Configuration --> DHCP Server.
The DHCP server default is disabled. Click on the Enable button to begin the configuration process.
Introduction78
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
Figure 57. DHCP Server web page
The server needs to have a subnet of IP addresses which will be allocated when a DHCP client makes a request.
Define the subnet by clicking on the hyperlink Create new Subnet... The next webpage, Create new DHCP Server subnet has four sections.
• Parameters for this subnet: defines the subnet and netmask, the origin of the subnet, maximum lease time,
and default lease time.
• IP addresses to be available on this subnet: either define the IP address range for the DHCP server IP pool,
or use the default range which is a set of 20 IP addresses.
• DNS server option information: enter the IP addresses of the primary and secondary DNS servers which
are provided to the DHCP clients.
• Default gateway option information: You may use the local host as the default gateway.
Figure 58 shows the entire configuration web page for the DHCP server.
Introduction79
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
Figure 58. DHCP server configuration web page
Parameters for the DHCP Server subnet
Four parameters are in the section for defining the DHCP subnet. (See figure 59.)
Figure 59. DHCP Server subnet parameters
The first two parameters are applicable when you will define the subnet.
• Subnet value: It is necessary to enter the selected value here and the ‘Subnet mask’ if you do not ‘Get subnet
from IP interface.’ See description for the 3rd parameter.
• Subnet mask
Introduction80
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
The third parameter is
• Get subnet from IP interface: If you use this option, then you will not enter any values in the first two
parameters. Should you define another subnet and also select Get subnet from IP interface, the Black Box
uses the Get subnet from IP interface as the ruling parameter and sets Subnet value and Subnet mask appropriately, overriding your initial selection. The ip1 Ethernet interface is always one option. However there may
be a WAN interface also as an additional option. The interface is the DHCP server “listening” interface. It
listens for client requests on this interface.
The two remaining parameters are:
• Maximum lease time: the default value is 86,400 seconds.
• Default lease time: the default value is 43,200 seconds.
IP Addresses to be available on this subnet
The next section (see figure 60) has three parameters:
• Start of address range: Enter the first IP address to be available in the DHCP IP address pool.
• End of address range: Enter the last IP address to be available in the DHCP IP address pool.
Figure 60. DHCP IP address pool
• Use a default range: Checking this box will give you an IP address pool of 20 contiguous addresses. This set-
ting, when checked, overrides anything entered in the Start and End of address range.
If you have selected Get subnet from IP interface and have checked the Use a default range, the first of the twenty
IP addresses will be the next sequential address following the IP address of the IP interface. For example,
Introduction81
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
assume that the IP address of ip1 is 10.10.19.10/16. Figure 61 shows that the IP address pool ranges from
10.10.19.11 to 10.10.19.30.
Figure 61. Example based on default range of IP address pool
DNS server option information
When a client requests an IP address from a DHCP server, the server can also send the IP addresses of the primary and secondary DNS servers’ IP addresses. The Black Box can accomplish this in one of two ways, neither
really having an advantage over the other. This section of the configuration page is one method, the other is
DNS Relay to be described later in this chapter. Refer to figure 62.
Figure 62. Configuration of the DNS server IP addresses
Enter the IP addresses of the primary and secondary DNS servers. Subsequently, the client will receive these
addresses when assigned an IP address. When the client makes a DNS inquiry, it sends the request directly to
the appropriate DNS server. The WAN Access Router merely forwards the packet.
The third parameter is ‘Use local host address as DNS server’ which is the IP address of the Black Box. In this
scenario, the client considers the Black Box as a DNS server by sending all requests to the Black Box’s IP
address. The Black Box forwards the request to the DNS servers using the IP address of the actual servers. You
still need to define the IP addresses of the primary and secondary DNS servers in the section because the Black
Box needs to know in order to forward the DNS requests.
Default gateway option information

Additional option information
You may wish to provide additional information to the clients on the DHCP subnet. Click on the hyperlink
Create new DHCP option... to access the configuration webpage. The options can specify:
• A default gateway
• Domain name
• IRC server
• HTTP server
• SMTP server
• POP3 server
• NNTP server
• WINS server
• Time servers
Refer to figure 63 as an example of multiple options to be sent to the clients.
Figure 63. DHCP server optional information example
DHCP Relay
With this webpage, you can enter a list of IP addresses for DHCP servers. When a client requests an IP address,
it uses one of the DHCP addresses listed in the DHCP relay webpage. The Black Box forwards (or ‘relays’) the
request to the DHCP server.
NoteDo not use the Black Box’s DHCP server if the DHCP Relay is enabled.
Configuration of the DHCP Relay
The DHCP Relay webpage has three sections. (See figure 64.)
• Enable/disable: The button in the first section enables or disables the DHCP relay on the WAN
Access Router.
• Edit DHCP server list: The IP addresses of DHCP servers can be updated, reset, or deleted from the list.
• Add new DHCP server: the IP addresses of the DHCP servers are added to the DHCP relay list in
this section.
Introduction83
WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration
In the first section of the DHCP Relay webpage, click on the Enable button on the DHCP Relay webpage.
Figure 64. DHCP Relay webpage
In the third section of the DHCP Relay webpage, enter the IP address of a DHCP server, and click on the Create button. (See figure 65.) The IP addresses will appear in the section, Edit DHCP server list.
In the second section, you may update or delete the DHCP server IP addresses. (See figure 65.)
To update or change a DHCP server IP address, enter the desired IP address over the IP address which is no
longer valid. Click on the Update button. With this action, you do not need to delete the IP address and subsequently add a new IP address. It is one action.
To delete a DHCP server IP address, check the Delete? box for the appropriate IP address and click on the
Update button.
Introduction84

DNS Relay
The DNS Relay webpage contains a configurable list of DNS server IP addresses. The Black Box’s DNS Relay
forwards DNS queries from a client to a pre-defined DNS server and DNS server responses to the client.
You can configure the DNS Relay for two IP addresses. These are for access to primary and secondary
DNS servers.

Introduction
The following system services can be enabled or disabled:
• DNS Relay
• FTP
• TFTP
• SNMP
• WEB Server.
The importance of disabling any of these services is an issue of security. If you are not using a particular service,
it is best to disable it. By disabling it, the associated port is not active, which means it is not available to abuse
with the intent of unauthorized access.
Figure 69. System Services configuration web page
WEB Server
The System Service which must be wisely disabled is the WEB Server. After you disable the WEB Server from
the web page, you can no longer access the any of the Black Box’s web pages. The only way to enable it is
through the Command Line Interface (CLI).
CLI Configuration
After configuring a terminal emulator to access the Black Box’s serial port, there are two commands for the
enabling or disabling the WEB Server. The following command enables the WEB Server so you can access the
management web pages via a browser. Remember that by only doing this command, the change is saved only
in volatile memory. Be sure to execute the next command to save it in non-volatile memory.
