BASICS > Quickstart

The first time you start up your 2247-N8 and connect to the web management interface, the 2247-N8 automatically displays the Quickstart page. This page leads you through the very basic steps of controlling access to your Web management interface and attempting a basic connection to your service provider’s network.

Basics > Quickstart Page

How to - connect to your service provider’s network and access the Internet:

1. Install, turn on, and log into the 2247-N8, as described in “Connecting the Gateway” on page 6, and in “Wireless (Wi-Fi) Network Setup” on page 8 or “Wired (Ethernet) Network Setup” on page 10. When you first connect to the Web management interface through your Web browser, the

2. Select if you will require a password or access code to use the Web management interface in the future. Read the information on the Quickstart page and choose your access restriction setting. Click the Allow Unrestricted LAN Access pull-down menu and choose On or Off.

 To allow connections to the web management interface without access code (password) authentication, you will turn Unrestricted LAN Access

On.

IMPORTANT: Motorola does not recommend allowing unrestricted LAN access to your 2247-N8. Not securing the Web management interface means

that anyone who has physical access to the 2247-N8 can make changes to your device configuration, and can bypass or eliminate security restrictions, change passwords, lock you out of the management interface, and disrupt your broadband connection.

 To require the use of a password, you will turn it Off, then set your access code, as described in the following steps.

3. Choose the access code that you will use for accessing the Web management interface:

 To use the access code that was assigned to the 2247-N8 in the factory, click the Use Default Access Code button.

Note: The default access code is printed on a label affixed to the bottom of the 2247-N8, labeled “Device Access Code”.

 To use a new, custom access code:

a. Type the default access code (from the label on the bottom of the 2247-N8) in the Enter Old Access Code input field.

b. Type a new access code (password) in the Enter New Access Code field, then type it again in the Retype New Access Code field. Choose a code

that is easy for you to remember but difficult for someone else to guess.

c. Click the Use New Access Code button.

After you make your choice between restricted and unrestricted LAN access (you can change it later - see “Acc ess C od e” on page 29), the 2247-N8 Web Interface displays a simplified Broadband Configuration page.

Quickstart Broadband Configuration Fields

4. Click the Connection Type pull-down menu and click the type of DSL connection that your service provider supplied to your DSL enabled tele- phone line:

 PPPoE: for Point to Point Protocol over Ethernet broadband service. In the United States, PPPoE is the most common Point to Point Protocol

ADSL service type available.

 PPPoA: for Point to Point Protocol over Asynchronous Transfer Mode (ATM) broadband service. If your service provider uses an ATM broad-

band connection to support your ADSL service, choose this selection.

 DHCP Client: for an ADSL connection that uses Dynamic Host Configuration Protocol to configure the broadband connection type and settings

for the 2247-N8.

5. Type the user name assigned to you by your service provider in the PPP Username field.

Note: the user name value may be a single word, or it may contain “@” symbols and periods (e.g: “myname@mydslservice.net”).

6. Type the password that your service provider assigned when the ADSL connection was installed or set up in the PPP Password field. To confirm that the password was entered correctly, type the password again in the Retype Password field.

7. Click the Finish button. The Motorola 2247-N8 DSL Wi-Fi Gateway will attempt to make a connection to the service provider network. This process may take a few minutes,

and your Web management interface may update automatically to show you the “Home” page during the process.

Note: If the Quickstart page fails to connect to the service provider’s network, contact your service provider and double-check your user name and

password. If you are still having difficulty connecting, you may attempt the more detailed broadband configuration available on the “Configure” page described on page 46.

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

BASICS > Alias

The Alias page allows devices on the 2247-N8 network to be identified by descriptive alias names, instead of IP or MAC addresses. Use it to assign easy to remember names to devices on your network. The alias names assigned from this page do not change the client configurations, they only appear in the pages of the 2247-N8 Web management interface. These aliases provide a means to identify devices more easily than a numerical IP or MAC address. New aliases can be assigned to known devices, or created in advance for devices that you plan to add to the network.

Basics > Alias Page

If any devices have been assigned aliases on your system, the Device Alias page shows them in an Alias List table. The Alias List table shows the following information for each device:

 Alias: The custom alias name assigned to the device.  Key: The type of address (MAC or IP) that the alias is associated with.  Value: the IP or MAC address identifying the device.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 25

Page 26

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

How to - add new device aliases to the 2247-N8:

Start at the Basics > Alias page.

1. Enter the IP or MAC address of the device:

a. If the device has already connected to the 2247-N8 networks, find and click the device address in the Device IP Addresses or Device MAC

Addresses

lists.

Note: If the device that you are defining an alias for uses DHCP to obtain an IP address, associate the new alias with the device’s MAC address. Associ-

ating the alias with the IP address may cause the device alias to be automatically assigned to a different device as it “follows” the dynamically assigned IP address.

b. If the device has not connected to the 2247-N8 networks, you may type either an IP or MAC address in the Manual Entry input field.

2. Type an alias in the Alias Name input field.

3. Click the Add button. The new alias is added to the Alias List table.

How to - delete device alias definitions:

You may delete any alias definition by clicking on the associated Delete button in the Alias List table. Deleting the alias does not remove the device from the network, it only removes the alias name from the device - the 2247-N8 will still record the device’s IP or MAC address in logs and messages.

System > Restricted Hosts

The System > Restricted Hosts page lets you control access to the Internet through the 2247-N8. This restriction can be used to set “windows” of time during which certain computers on your network are allowed access to the Internet. Additionally, an access “budget” of time may be defined for devices on the network, defining the maximum number of hours that the device may access the Internet on that date. Host restriction also allows for the creation of accounts that provide access only to the 2247-N8’s Internet connection, or that deny network and Internet access entirely.

System > Restricted Hosts Page

Host restriction is accomplished by creating Access Profiles, each of which may have custom configurations for the days of the week. Those profiles are then applied to known devices.

Note: Restricted Host profiles require the configuration of the 2247-N8s time zone, as described in “Timezone” on page 41.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 38

Page 39

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

How to - restrict the time of day or number of hours computers may access the Internet through the 2247-N8:

Open the System > Restricted Hosts page.

Host restriction requires the creation of at least one Access Profile to define a set of rules. Once one or more profiles are created, they may be applied to devices on your network as described in “How to assign (or remove) Internet access restrictions to specific computers on your net-

work:” on page 40.

1. Click the Add New Profile button. A new profile is created in the Access Profile table of the Restricted Hosts page.

How to - assign (or remove) Internet access restrictions to specific computers on your network:

You may assign a pre-defined Wi-Fi user restriction profile (the GuestNetwork or Blacklist default profiles) or a custom profile (created in “How to

restrict the time of day or number of hours computers may access the Internet through the 2247-N8:” on page 39) to devices on your network.

Open the System > Restricted Hosts page.

Note: this procedure requires that the computers to restrict are “known” to the 2247-N8. Simply connecting to the 2247-N8 wired or wireless network

will let the 2247-N8 discover the device. You may also refresh the list as described in “How to scan for computers on your local networks” on page 24. It may be easier to identify specific devices in the table if you first assign an alias to them, as described in “How to add new device aliases to the

2247-N8:” on page 26.

1. Locate the computer that you want to restrict in the Device Restriction table at the bottom of the page. This table lists all client devices that the 2247-N8 has learned the MAC (hardware) address of.

2. Click the Restriction Type pull-down menu associated with the device. Select a restriction type to apply to the device:

 None: give the device unrestricted access to the Internet.  GuestNetwork (for Wi-Fi users only): restrict the wireless device from accessing any computers on your home (wired or Wi-Fi) network.  Blacklist (for Wi-Fi users only): restrict the wireless device from accessing the Internet, or any computers on the home networks.  ProfileX: Select a profile (where “X” is the profile number) listed in the pull-down menu to enforce the chosen access profile on that device.

3. Repeat the selection process for any devices that you want to apply an access restriction to. You may assign the same access profile to any number of devices known to the 2247-N8.

4. Click the Save button to assign the access profile(s) to the devices.

How to - configure security for your wireless network:

Choose a Wireless security method from the following list, which is ranked from most secure to least secure:

 WPA - PSK: Wireless Protected Access with Pre-Shared Key is designed for home and small office wireless networks that do not require the

security level provided by authentication servers and other security methods. It relies on a key that you set on the 2247-N8 and then manually enter on any device that you add to the Wi-Fi network. WPA uses this key to create an encryption code that wireless clients and the 2247-N8 use to protect and encode wireless traffic.

 WPA - Default Key: Wireless Protected Access with a default key uses a hardware identification code (in the 2247-N8’s case, the Device

Access Code, described in “Acc ess Cod e” on page 29) that you must enter on any device that joins the network. Like WPA-PSK, the code is used to encrypt all wireless traffic between approved devices and the 2247-N8. WPA - Default Key is the factory default security setting used on the 2247-N8.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 75

Page 76

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

 WEP - Manual: Wired Equivalent Protocol is an older security standard that is not recommended if the devices on your Wi-Fi network can

support either WPA mode (above). The WEP - Manual method uses a manually set shared key to encrypt all packets. Due to the operation of the encryption, it is easier to decode packets and determine the encryption key for WEP than for the WPA security methods.

 No Privacy: This mode eliminates all privacy and security, and allows any device to connect to the Wi-Fi network without encryption or the

use of a password or key. This mode is not recommended.

In addition, the 2247-N8 supports Wi-Fi Protected Setup (WPS), which simplifies the configuration and use of security and privacy on the wireless network, but is less secure than the more demanding WPA methods.

Note: If you will be using a WPA protection method on your 2247-N8 wireless network, you may enhance security by disabling Wi-Fi Protected Setup,

as described later in this section.

Open the Wireless > Configure page.

Refer to the procedure below that describes how to configure your selected security method.

To conf igure WPA-PSK Security:

1. Select WPA - PSK from the Security pull-down menu. Wait a moment for the page to refresh and show the WPA-PSK related configuration fields.

2. Click the WPA Version pull-down menu and select the WPA version (WPA-1 or WPA-2) that devices joining the network will use. Select Both (the default) to have the 2247-N8 and the connecting devices automatically determine and use the most secure WPA version that both devices support.

3. Type a custom key value, which must also be entered in the Wi-Fi configuration of all devices that will connect to the 2247-N8 network, in the Key input field. The WPA key may be between 8 and 64 characters, including numbers, mixed upper and lower case letters, special characters, and spaces. Choose a key that is easy for you to remember, but difficult for someone else to guess.

4. Click the Save button to start using the new Wi-Fi security settings and key on the 2247-N8.

1. Click the Service pull-down menu and click the name of the application or game in the list. Click on the Service Details button after choosing an application if you want to examine and adjust the details of the protocols and ports used to

support the application.

Note: if the service, game, or application that you want to add the exception for is not in the list, you must define it as described in “How to define a

custom service for firewall hosted applications:” on page 87, then repeat this procedure.

2. Click the Needed by Device pull-down menu, and select one of the known devices on your home or wireless network that will “host” the application. If you have multiple computers that need to act as hosts for a single application, you must add them separately by repeating the exception process.

3. Click the Add button to create the application hosting exception. The new exception is listed in the Hosted Applications portion of the Firewall >

NAT/Gaming

page.

How to - define a custom service for firewall hosted applications:

Open the Firewall > NAT/Gaming page.

1. Click the Custom Services button. The Custom Services functions of the NAT/Gaming page are shown

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 87

Page 88

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

2. Type the name of the service, game, or application that you want to add to the Service menu (list of hosted applications) of the NAT/Gaming page in the Service Name field.

3. Specify the starting and ending port range used by the hosting application. Type the starting and ending port numbers in the Global Port Range input fields. These values will be between 1 and 65535. The specific values to use are dependent upon the hosting application, and the information is available from the application’s publisher or creators.

If you only need a single port to support the application, enter the same port number in both fields (e.g.; “12620” - “12620”).

4. Type a base port number in the Base Host Port input field. In most cases, this will be the same as the first number in your Global Port Range val- ues.

5. Click the Protocol pull-down menu and choose the protocol type that the hosted application requires from the list.

Note: if the application you are adding to the services list uses multiple port ranges or multiple protocols, you must create separate service entries for

each port and protocol combination.

6. Click the Add button to define the new custom service entry. The new entry is added to the list. All custom entries are identified by a “*” prefix in front of their Service Name in the list.

You may repeat this procedure, from step 2 forward, to define additional pinhole ranges or add additional services.

Firewall > Packet Filter

The 2247-N8 firewall can filter packets based on custom criteria. You create and enable these filtering rules with the Firewall > Packet Filter page.

Firewall > Packet Filter Page

Note: Use caution when creating and implementing filters. Improperly adding filters and filtersets increases the possibility of loss of communication

with the 2247-N8 and the Internet.

Filters are not a substitute for password protection, effective safeguarding of passwords, and general awareness of how your network may be vulnerable.

Before creating filters, you should read the next few sections to learn more about how these powerful security tools work.

Parts of a packet filter

A packet filter consists of criteria based on packet attributes. A typical filter can match a packet on any one of the following attributes:

 The source IP address (where the packet was sent from)  The destination IP address (where the packet is going)  The type of higher-layer Internet protocol the packet is carrying, such as TCP or UDP  The port number of the session source or destination  The packet’s incoming or outgoing 2247-N8 interface (WAN or LAN)  The source or destination MAC address  Any TCP packet flags (i.e. ACK, URG, etc)  The ICMP type value of an ICMP packet

Once a match attribute is selected, it cannot be added again to the same rule - filtering on variations of the same attribute (multiple destination addresses, for example) requires the creation of multiple packet filter rules.

Other filter attributes

There are three other attributes to each filter:

 The rule’s order (i.e., priority) in the packet filter  Whether the rule is currently active  Whether the rule is set to pass packets or to block (discard) packets.

Note: “Pass” rules are especially useful when you have created a Public Subnet and Allow Inbound Traffic is disabled. You can selectively allow access

to particular servers, or particular services on those servers (by TCP/UDP port range).

Design guidelines

Careful thought must go into designing a new packet filter. You should consider the following guidelines:

 Be sure the packet filter’s overall purpose is clear from the beginning. A vague purpose can lead to a faulty set, and that can actually make

your network less secure.

 Be sure each individual rule’s purpose is clear.  Determine how rule priority will affect the set’s actions. Test the set (on paper) by determining how the packet filters would respond to a

number of different hypothetical packets.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 90

Page 91

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

 Consider the combined effect of the rules. Because packets that don't match any rule are implicitly allowed, you may want to consider adding

a catch-all rule as your final rule that exhibits the desired behavior for otherwise-unmatched packets. Be careful that you don't preclude necessary traffic. (Since packet filters only apply to packets traveling through the 2247-N8, and not to it, you need not worry that you will lock yourself out from being able to re-configure the device via a Web browser.)

An approach to using filters

The ultimate goal of network security is to prevent unauthorized access to the network without compromising authorized access. Using the packet filter is part of reaching that goal.

Each rule you design will be based on one of the following approaches:

 That which is not expressly prohibited is permitted.  That which is not expressly permitted is prohibited.

It is strongly recommended that you take the latter, and safer, approach to all of your rule designs. If you do so, you should create a catch-all rule as your final rule.

How to - control packet filter operation:

Open the Firewall > Packet Filter page.

The 2247-N8 Packet Filter is enabled by default, but it does not have any custom packet filter rules applied. The Packet Filter system may be enabled or disabled (turned on or off) by clicking the Disable Packet Filters / Enable Packet Filters button on the Firewall > Packet Filter page.

How to - add and create packet filter rules:

Open the Firewall > Packet Filter page.

1. Click on the type of packet filtering rule you wish to create:

 Click Add a Pass Rule to create a new rule that expressly permits a packet that meets the rules criteria  Click Add a Drop Rule to make a new filter rule that blocks a packet that meets the rules criteria.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 91

Page 92

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

A new rule of the selected type is added to the Packet Filter Rules section of the page.

The new rule contains a default IP Version of “IPv4 or IPv6” rule, which means that both incoming IPv4 and IPv6 addressed packets will match the rule.

2. Click the Add Match... button of the new rule to specify the first filtering criterion of the rule. A Match Entry window opens.

3. Click the Match Type pull-down menu. Choose the type of “test” that you want the match entry to apply to all packets.

 Source IP Address, with an input field for the IP address to match.  Destination IP Address, with an input field for the IP address to match.  Protocol, with sub-selections; TCP, UDP, by number, or by name, with an input field for number or name values.  Ingress Interface, with a pull-down submenu to choose the incoming LAN or WAN interface.  Egress Interface, with a pull-down submenu to choose the outbound LAN or WAN interface.  Source MAC Address, with a list of known devices and a manual MAC address entry input field.  Destination MAC Address, with a list of known devices and a manual MAC address entry input field.  Source Port number, with input fields for the starting and ending port numbers that define the port range.  Destination Port number, with input fields for the starting and ending port numbers that define the port range.  TCP Flag (if Protocol is selected with TCP as a sub-selection), with an activation table for examining or setting TCP packet flags.  ICMP Type (if Protocol is selected with ICMP as a sub-selection), with an entry field for the type match value.

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 92

Page 93

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

Depending on the match that you choose, you must type or click specific values that the filter rule will compare the filtered packets to: Some Match Types (such as TCP Flag) may also be dependent on the selection of prerequisite matches.

4. Click the Enter Match button to close the Match Entry window.

5. Repeat step 2 through step 4 to add up to nine (total) match “tests” to the filter rule.

6. Repeat step 1 (selecting a Pass Rule or a Drop Rule), and the steps for adding match types to the rule to assign additional filtering operations to the packet filter.

Any filter set rules that you create are automatically saved to the 2247-N8.

How to - modify, disable, or delete packet filter rules:

Open the Firewall > Packet Filter page.

Packet filter rules may be changed or deleted from the Packet Filter Rules table of the Firewall > Packet Filter page. Use the controls in the

Packet Filter Rules table to:

 Change the order in which Pass or Drop rules are performed on packets with the up and down arrows to the right of the rule Order number.  Enable or disable individual Pass or Drop rules with the Enabled check box.  Change the match criteria of a rule by clicking on the underlined text describing the rule’s match.

Note: an enabled rule cannot be modified. To change the match criteria of a rule, you must first disable the rule by clicking on the associated Enabled

check box.

 Delete a match from a rule, or delete a rule, by clicking the Delete button associated with the match or rule.

Any rule or match changes that you make are automatically saved to the 2247-N8.

Firewall > DoS Protection

The Firewall > DoS Protection page of the 2247-N8 provides controls for “tuning” the firewall settings that are relevant to most Denial of Service (DoS) attacks. While the default configuration of the 2247-N8 firewall provides protection against common DoS attacks, these settings may be adjusted for special situations using these controls.

Firewall > DoS Protection Page

Please visit www.motorola.com/us/support for FAQs and additional product documentation. 97

Page 98

Motorola 2247-N8 DSL Wi-Fi Gateway User Guide

How to - modify Denial of Service (DoS) protection settings:

Open the Firewall > DoS Protection page.

Use the pull-down menus and input fields of the Firewall > DoS Protection page to control the operation of the system firewall’s detection and handling of DoS attempts:

 Drop packets with invalid source or destination IP address: Whether packets with invalid source or destination IP address(es) are to be

dropped

 Protect against port scan: Whether to detect and drop port scans.  Drop packets with unknown ether types: Whether packets with unknown ethernet types are to be dropped  Drop packets with invalid TCP flags: Whether packets with invalid TCP flag settings (NULL, FIN, Xmas, etc.) should be dropped  Drop incoming ICMP Echo requests: Whether all ICMP echo requests are to be dropped.

The Flood Limit pull-down menu determines if the 2247-N8 should detect and control packet flooding events. The fields below the Flood Limit pull-down menu are only available if flood limiting is enabled.

 Flood Limit: Whether packet flooding should be detected and offending packets be dropped;.  Flood rate limit: Specifies the number limit of packets per second before dropping the remainder.  Flood burst limit: Specifies the number limit of packets in a single burst before dropping the remainder.  Flood limit ICMP enable: Whether ICMP traffic packet flooding should be detected and offending packets be dropped  Flood limit UDP enable: Whether UDP traffic packet flooding should be detected and offending packets be dropped.  Flood limit UDP Pass multicast: Allows exclusion of UDP multicast traffic. On by default.  Flood limit TCP enable: Allows exclusion of TCP traffic. Off by default.  Flood limit TCP SYN-cookie: Allows TCP SYN cookies flooding to be excluded.

IPv6 Protection:

The following controls are only available on the Firewall > DoS Protection page if the 2247-N8 is using IPv6. Configuration of IPv6 is found in

“IPv6” on page 52.

 Neighbor Discovery Attack protection: Prevents downstream traffic from an upstream device that sends excessive traffic but receives no

replies.

 ESP Header Forwarding: Allows the use of Encapsulating Security Payload (ESP) data payload encryption for IP Secure (IPsec) from qualify-

ing endpoints.

 Authentication Header Forwarding: Accept and forward IPSec packets with Authentication Headers, which may be used by some IPSec

implementations to validate packet sources.

 Reflexive ACL: When IPv6 is enabled, Reflexive Access Control Lists can deny inbound IPv6 traffic unless this traffic results from returning

outgoing packets (except as configured through firewall rules).

After making any changes to the DoS protection settings, click the Save button to assign the new configuration to the 2247-N8.
