This Gateway connects your local network, or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks. The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers. This is how your network remains private. The Gateway protects your network by inspecting every packet coming in through the Internet port before delivery to the appropriate computer on your network. The Gateway inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate computer on your network. Remember that the Gateway’s ports connect to two sides. The network ports connect to your network, and the ADSL port connects to the Internet. The network ports transmit data at 10/100Mbps. IP Addresses What’s an IP Address? IP stands for Internet Protocol. Every device on an IP-based network, including computers, print servers, and Gateways, requires an IP address to identify its “location,” or address, on the network. This applies to both the Internet and network connections. There are two ways of assigning an IP address to your network devices. You can assign static IP addresses or use the Gateway to assign IP addresses dynamically. Static IP Addresses A static IP address is a fixed IP address that you assign manually to a computer or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses must be unique and are commonly used with network devices such as server computers or print servers. Chapter 1: Planning Your Network The Gateway’s Functions Figure 1-1: Network NOTE: Since the Gateway is a device that connects two networks, it needs two IP addresses—one for your network, and one for the Internet. In this User Guide, you’ll see references to these address.” Since the Gateway uses NAT technology, the only IP address that can be seen from the Internet for your network is the Gateway’s Internet IP address. However, even this Internet IP address can be blocked, so that the Gateway and network seem invisible to the Internet—see the Block WAN Requests description under Security in Chapter 4: Configuring the Gateway. Wireless-G ADSL Gateway with 2 Phone Ports Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Gateway. You can get that information from your ISP. Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device. After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address. DHCP (Dynamic Host Configuration Protocol) Servers Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The computer or networking device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. A DHCP server can either be a designated computer on the network or another network device, such as the Gateway. By default, the Gateway’s DHCP Server function is enabled. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Gateway, see the DHCP section in Chapter 4: Configuring the Gateway. What is a VPN? A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Gateway, for instance - in different networks that allows private data to be sent securelybetween networks. This establishes a private network that can send data securely between these two locations or networks. This is done by creating a “tunnel”. A VPN tunnel connects the two computers or networks and allows data to be transmitted over the Internet as if it were still within those networks. While not a literal tunnel, this is a connection secured by encrypting the data sent between the two networks. VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual Private Networking can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN Gateway using any computer with VPN client software that supports IPSec, such as SSH Sentinel.) Chapter 1: Planning Your Network What is a VPN? Wireless-G ADSL Gateway with 2 Phone Ports There are two basic ways to create a VPN connection: • VPN Gateway to VPN Gateway • Computer (using VPN client software that supports IPSec) to VPN Gateway The VPN Gateway creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software that supports IPSec can be one of the two endpoints. Any computer with the built-in IPSec Security Manager (Microsoft 2000 and XP) allows the VPN Gateway to create a VPN tunnel using IPSec (refer to Appendix C: Configuring IPSec between a Windows 2000 or XP computer and the VPN Gateway). Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPSec to be installed. Computer (using VPN client software that supports IPSec) to VPN Gateway The following is an example of a computer-to-VPN Gateway VPN. In her hotel room, a traveling businesswoman dials up her ISP. Her notebook computer has VPN client software that is configured with her office's VPN settings. She accesses the VPN client software that supports IPSec and connects to the VPN Gateway at the central office. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office's network, as if she were physically connected. Figure 1-2: Computer-to-VPN Gateway IMPORTANT: You must have at least one VPN Gateway on one end of the VPN tunnel. At the other end of the VPN tunnel, you must have a second VPN Gateway or a computer with VPN client software that supports IPSec. Chapter 1: Planning Your Network What is a VPN? Wireless-G ADSL Gateway with 2 Phone Ports VPN Gateway to VPN Gateway An example of a VPN Gateway-to-VPN Gateway VPN would be as follows. At home, a telecommuter uses his VPN Gateway for his always-on Internet connection. His Gateway is configured with his office's VPN settings. When he connects to his office's Gateway, the two Gateways create a VPN tunnel, encrypting and decrypting data. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office's network, as if he were physically connected. For additional information and instructions about creating your own VPN, please visit Linksys’s website at www.linksys.com or refer to Appendix C: Configuring IPSec between a Windows 2000 or XP computer and the VPN Gateway. Why do I need a VPN? With the flexibility that comes with computer networking, there is also an increased risk in security. This is why firewalls were first introduced. Firewalls help to protect data inside of a local network. But what do you do once information is sent outside of your local network, when emails are sent to their destination, or when you have to connect to your company's network when you are out on the road? How is your data protected? That is when a VPN can help. VPNs secure data moving outside of your network as if it were still within that network. When data is sent out across the Internet from your computer, it is always open to attacks. You may already have a firewall, which will help protect data moving around or held within your network from being corrupted or intercepted by entities outside of your network, but once data moves outside of your network - when you send data to someone via email or communicate with an individual over the Internet - the firewall will no longer protect that data. Figure 1-3: VPN Gateway-to-VPN Gateway At this point, your data becomes open to hackers using a variety of methods to steal not only the data you are transmitting but also your network login and security data. Some of the most common methods are as follows: 1) MAC Address Spoofing Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header. These packet headers contain both the source and destination information for that packet to transmit efficiently. A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user. Chapter 1: Planning Your Network Why do I need a VPN? Wireless-G ADSL Gateway with 2 Phone Ports 2) Data Sniffing Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text. 3) Man in the Middle Attacks Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the middle” attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the data to a new destination. Even though the data is not received by its intended recipient, it appears that way to the person sending the data. These are only a few of the methods hackers use and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the Internet will often pass through many different servers around the world before reaching its final destination. That's a long way to go for unsecured data and this is when a VPN serves its purpose. Chapter 1: Planning Your Network Why do I need a VPN?

Chapter 2: Getting to Know the Wireless-G ADSL Gateway with 2 Phone Ports The Front Panel Wireless-G ADSL Gateway with 2 Phone Ports Chapter 3: Connecting the Wireless-G ADSL Gateway Overview The Gateway’s setup consists of more than simply plugging hardware together. You will have to configure your networked computers to accept the IP addresses that the Gateway assigns them (if applicable), and you will also have to configure the Gateway with setting(s) provided by your Internet Service Provider (ISP). The installation technician from your ISP should have left the setup information for your modem with you after installing your broadband connection. If not, you can call your ISP to request that data. After you have the setup information you need for your specific type of Internet connection, you can begin installation and setup of the Gateway. If you want to use a computer with an Ethernet adapter to configure the Gateway, continue to “Wired Connection to a computer.” If you want to use a computer with a wireless adapter to configure the Gateway, continue to “Wireless Connection to a Computer.” Chapter 3: Connecting the Wireless-G ADSL Gateway Overview Wireless-G ADSL Gateway with 2 Phone Ports Wired Connection to a Computer 1. Before you begin, make sure that all of your network’s hardware is powered off, including the Gateway and all computers. 2. Connect one end of an Ethernet network cable to one of the Ethernet ports (labeled 1-4) on the back of the Gateway, and the other end to an Ethernet port on a computer. Repeat this step to connect more computers, a switch, or other network devices to the Gateway. Figure 3-1: Connecting your networking devices 3. Connect a phone cable from the Line port on the Gateway’s back panel to the wall jack of the ADSL line. NOTE: A small device called a microfilter (not included) may be necessary between each phone and wall jack to prevent interference. Contact your ISP if you have any questions. IMPORTANT: For countries that have phone jacks with RJ-11 connectors, make sure to only place the microfilters between the phone and the wall jack and not between the Modem and the wall jack or your ADSL will not connect. Figure 3-2: Connecting your ADSL line For countries that do not have phone jacks with RJ-11 connectors (e.g. France, Sweden, Switzerland, United Kingdom, etc.), except for ISDN users, the microfilter has to be used between the modem and the wall jack, because the microfilter will have the RJ-11 connector. Annex B users must use the included special cable to connect the gateway to the wall jack (RJ-45 to RJ-12). If you require splitters or special jacks, please contact your service provider. 4.

The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network. Local DHCP Server. A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP address to each computer on your network for you. Unless you already have one, you should leave the Gateway enabled as a DHCP server. DHCP Relay Server. If you have a local DHCP server that you would like to use instead, enable the DHCP Relay mode for the Local DHCP Server setting and enter the IP address of the DHCP server. Chapter 4: Configuring the Gateway The Setup Tab 23 Wireless-G ADSL Gateway with 2 Phone Ports AutoDetect LAN DHCP Server. If you want the Gateway to automatically detect a DHCP server on the local network, then select the Enable radio button. (When this feature is enabled, the DHCP Relay radio button for the Local DHCP Server setting will be unavailable.) Otherwise, keep the default, Disable. Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default Starting IP Address is 192.168.1.100. Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50. Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased” this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day. Static DNS (1-3). The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers. Figure 4-10: Basic Setup Tab - Network Setup WINS.

Chapter 4: Configuring the Gateway The Wireless Tab 28 Wireless-G ADSL Gateway with 2 Phone Ports Wireless Security Tab The Gateway’s wireless security settings configure the security of your wireless network. There are three wireless security mode options supported by the Gateway: WPA Pre-Shared Key, WPA RADIUS, and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These are briefly discussed here. For detailed instructions on configuring wireless security for the Gateway, turn to Appendix B: Wireless Security. If you want to disable wireless security, select Disable from the drop-down menu for Security Mode. WPA Pre-Shared Key. Enter a WPA Shared Key of 8-32 characters. Then, enter a Group Key Renewal period, which instructs the Gateway how often it should change the encryption keys. Figure 4-17: Wireless Tab - Wireless Security (WPA Pre-Shared Key) WPA RADIUS. This option features WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Gateway.) Enter the RADIUS server’s IP Address and port number, along with a key shared between the Gateway and the server. Then, enter a Key Renewal Timeout, which instructs the Gateway how often it should change the encryption keys. Figure 4-18: Wireless Tab - Wireless Security (WPA RADIUS) Chapter 4: Configuring the Gateway The Wireless Tab 29 Wireless-G ADSL Gateway with 2 Phone Ports WEP. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a Default Key (choose which Key to use), and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Then either generate a WEP key using a Passphrase or enter the WEP key manually. • WEP Encryption. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode data transmissions, all devices in a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. To enable WEP, select 64 bits (10 hex digits) or 128 bits (26 hex digits). • Default Transmit Key Select which WEP key (1-4) will be used when the Gateway sends data. Make sure that the receiving device (wireless client) is using the same key. • Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. This passphrase is used to generate one or more WEP keys. It is case-sensitive and should not be longer than 32 alphanumeric characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be used with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless products or Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and enter it manually in the wireless client.) After you enter the Passphrase, click the Generate button to create WEP keys. Figure 4-19: Wireless Tab - Wireless Security (WEP) • WEP Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.

Select from the range of speeds, or have the Gateway automatically use the fastest possible data rate, be default, and enable the Auto-Fallback feature. Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Gateway to synchronize the wireless network. DTIM Interval. The default value is 3. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Gateway has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. Fragmentation Threshold. This value should remain at its default setting of 2346. The range is 256-2346 bytes. It specifies the maximum size of a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor modifications of this value are recommended. RTS Threshold. This value should remain at its default setting of 2347. The range is 0-2347 bytes. If you encounter inconsistent data flow, only make minor modifications. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Gateway sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission.

IPSec VPN Tunnel The VPN Gateway creates a tunnel or channel between two endpoints, so that the data or information between these endpoints is secure. To establish this tunnel, select the tunnel you wish to create in the Select Tunnel Entry drop-down box. It is possible to create up to five simultaneous tunnels. Then click Enabled to enable the IPSec VPN tunnel. Once the tunnel is enabled, enter the name of the tunnel in the Tunnel Name field. This is to allow you to identify multiple tunnels and does not have to match the name used at the other end of the tunnel. To delete a tunnel entry, select the tunnel, then click Delete. To view a summary of the settings, click Summary. Figure 4-24: Security Tab - VPN Local Secure Group and Remote Secure Group. The Local Secure Group is the computer(s) on your network that can access the tunnel. The Remote Secure Group is the computer(s) on the remote end of the tunnel that can access the tunnel. These computers can be specified by a Subnet, specific IP address, or range. Figure 4-25: VPN Settings Summary Local Security Gateway. This pull-down menu will provide you with your available Internet connection options. Chapter 4: Configuring the Gateway The Security Tab 34 Wireless-G ADSL Gateway with 2 Phone Ports Remote Security Gateway. The Remote Security Gateway is the VPN device, such as a second VPN Gateway, on the remote end of the VPN tunnel. Enter the IP Address or Domain of the VPN device at the other end of the tunnel. The remote VPN device can be another VPN Gateway, a VPN Server, or a computer with VPN client software that supports IPSec. The IP Address may either be static (permanent) or dynamic (changing), depending on the settings of the remote VPN device. Make sure that you have entered the IP Address correctly, or the connection cannot be made. Remember, this is NOT the IP Address of the local VPN Gateway, but the IP Address of the remote VPN Gateway or device with which you wish to communicate. If you enter an IP address, only the specific IP Address will be able to acess the tunnel. If you select Any, any IP Address can access the tunnel. • Encryption. Using Encryption also helps make your connection more secure. There are two different types of encryption: DES or 3DES (3DES is recommended because it is more secure). You may choose either of these, but it must be the same type of encryption that is being used by the VPN device at the other end of the tunnel. Or, you may choose not to encrypt by selecting Disable. DES is selected by default. • Authentication. Authentication acts as another level of security. There are two types of authentication: MD5 and SHA (SHA is recommended because it is more secure). As with encryption, either of these may be selected, if the VPN device at the other end of the tunnel is using the same type of authentication. Or, both ends of the tunnel may choose to Disable authentication. In the Manual Key Management screen, MD5 (the default) has been selected. Key Management. Select Auto (IKE) or Manual from the drop-down menu. The two methods are described below. • Auto (IKE). Select Auto (IKE) and enter a series of numbers or letters in the Pre-shared Key field. Based on this word, which MUST be entered at both ends of the tunnel if this method is used, a key is generated to scramble (encrypt) the data being transmitted over the tunnel, where it is unscrambled (decrypted). You may use any combination of up to 24 numbers or letters in this field. No special characters or spaces are allowed. In the Key Lifetime field, you may select to have the key expire at the end of a time period. Enter the number of seconds you’d like the key to be useful, or leave it blank for the key to last indefinitely. Check the box next to PFS (Perfect Forward Secrecy) to ensure that the initial key exchange and IKE proposals are secure. • Manual. Select Manual, then select the Encryption Algorithm from the drop-down menu. Enter the Encryption Key in the field (if you chose DES for your Encryption Algorithm, enter 16 hexadecimal characters, if you chose 3DES, enter 48 hexadecimal characters). Select the Authentication Algorithm from the drop-down menu. Enter the Authentication Key in the field (if you chose MD5 for your Authentication Algorithm, enter 32 hexadecimal characters, if you chose SHA1, enter 40 hexadecimal characters). Enter the Inbound and Outbound SPIs in the respective fields. Figure 4-26: Auto Key Management Figure 4-27: Manual Key Management Status. The status of the connection is shown.

After Phase 1 is completed, Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions. Operation Mode. There are two modes: Main and Aggressive, and they exchange the same IKE payloads in different sequences. Main mode is more common; however, some people prefer Aggressive mode because it is faster. Main mode is for normal usage and includes more authentication requirements than Aggressive mode. Main mode is recommended because it is more secure. No matter which mode is selected, the VPN Gateway will accept both Main and Aggressive requests from the remote VPN device. Encryption. Select the length of the key used to encrypt/decrypt ESP packets. There are two choices: DES and 3DES. 3DES is recommended because it is more secure. Authentication. Select the method used to authenticate ESP packets. There are two choices: MD5 and SHA. SHA is recommended because it is more secure. Group.

Introduction The Linksys Parental Control Service makes it easy for you to keep your family safe on the Internet. The Service gives you powerful tools to control the availability of Internet services, access, and features, customizable for each member of the family. Choosing from 16 different web content categories, you control what each family member is allowed to see. Each website request triggers a search through our constantly updated database, which determines whether or not to allow the content through, based on who's logged in. You can also manually block or allow specific websites based on your own judgment. database: a collection of data that is organized so that its contents can easily be accessed, managed, and updated. To protect your family from unsolicited messages, you can set up e-mail and Instant Message filters. You select who can send messages to, and receive messages from, your family. If your children are spending too much time online, you can set time restrictions by hour and day of the week. To keep you informed of your family's online activities, full reports are available to view or download. You can see each family member’s blocked and unblocked Internet activities, to keep you “in the loop” on their changing interests. Setting up and customizing each family member’s settings is a snap with the friendly web-based menus—even if you're not the family's usual network administrator. Because the Parental Control Service is based in the Router, not your PCs, it can't be bypassed and keeps every Internet device in your household equally protected. * Available in US and Canada only.

D. In the command prompt, type ping www.yahoo.com and press the Enter key. • If you get a reply, the computer is connected to the Internet. If you cannot open a webpage, try the ping command from a different computer to verify that your original computer is not the cause of the problem. • If you do NOT get a reply, there may be a problem with the connection. Try the ping command from a different computer to verify that your original computer is not the cause of the problem. 3. I am not getting an IP address on the Internet with my Internet connection. • Refer to “Problem #2, I want to test my Internet connection” to verify that you have connectivity. 1. Make sure you are using the right Internet connection settings. Contact your ISP to see if your Internet connection type is RFC 1483 Bridged, RFC 1483 Routed, RFC 2516 PPPoE, IPoA or RFC 2364 PPPoA. Please refer to the Setup section of Chapter 4: Configuring the Gateway for details on Internet connection settings. 2. Make sure you have the right cable. Check to see if the Gateway column has a solidly lit ADSL LED. 3. Make sure the cable connecting from your Gateway’s ADSL port is connected to the wall jack of the ADSL service line. Verify that the Status page of the Gateway’s web-based utility shows a valid IP address from your ISP. 4. Turn off the computer and Gateway. Wait 30 seconds, and then turn on the Gateway, and computer. Check the Status tab of the Gateway’s web-based utility to see if you get an IP address. 4. I am not able to access the Setup page of the Gateway’s web-based utility. • Refer to “Problem #2, I want to test my Internet connection” to verify that your computer is properly connected to the Gateway. 1. Refer to Appendix D: Finding the MAC Address and IP address for Your Ethernet Adapter to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS. 2. Set a static IP address on your system; refer to “Problem #1: I need to set a static IP address.” 3. Refer to “Problem #10: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE users).” Appendix A: Troubleshooting Common Problems and Solutions 78 Wireless-G ADSL Gateway with 2 Phone Ports 5. I can’t get my Virtual Private Network (VPN) working through the Gateway. Access the Gateway’s web interface by going to http://192.168.1.1 or the IP address of the Gateway, and go to the Security tab. Make sure you have IPsec passthrough and/or PPTP pass-through enabled. • VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will work fine. At least one IPSec session will work through the Gateway; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs. • VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Gateway. AH has limitations due to occasional incompatibility with the NAT standard. • Change the IP address for the Gateway to another subnet to avoid a conflict between the VPN IP address and your local IP address. For example, if your VPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254) and your local IP address is 192.168.1.X (X is the same number used in the VPN IP address), the Gateway will have difficulties routing information to the right location. If you change the Gateway’s IP address to 192.168.2.1, that should solve the problem. Change the Gateway’s IP address through the Setup tab of the web interface. • If you assigned a static IP address to any computer or network device on the network, you need to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to 254). Note that each IP address must be unique within the network. • Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec server. Refer to “Problem #7, I need to set up online game hosting or use other Internet applications” for details. • Check the Linksys international website for more information at www.linksys.com/international. 6. I need to set up a server behind my Gateway and make it available to the public. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed. • Follow these steps to set up port forwarding through the Gateway’s web-based utility. We will be setting up web, ftp, and mail servers. 1. Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the Gateway. Go to the Applications and Gaming => Port Range Forwarding tab. 2. Enter any name you want to use for the Customized Application. 3. Enter the External Port range of the service you are using. For example, if you have a web server, you would enter the range 80 to 80. 4. Check the protocol you will be using, TCP and/or UDP. 5. Enter the IP address of the computer or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. Appendix A: Troubleshooting Common Problems and Solutions 79 Wireless-G ADSL Gateway with 2 Phone Ports 6. Check the Enable option for the port services you want to use. Consider the example below: Customized Application Web server FTP server SMTP (outgoing) POP3 (incoming) External Port 80 to 80 21 to 21 25 to 25 110 to 110 TCP UDP IP Address 192.168.1.100 192.168.1.101 192.168.1.102 192.168.1.102 Enable When you have completed the configuration, click the Save Settings button. 7. I need to set up online game hosting or use other Internet applications. If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Gateway to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way to get the information on what port services to use is to go to the website of the online game or application you want to use. Follow these steps to set up online game hosting or use a certain Internet application: 1. Access the Gateway’s web interface by going to http://192.168.1.1 or the IP address of the Gateway. Go to the Applications and Gaming => Port Range Forwarding tab. 2. Enter any name you want to use for the Customized Application. 3. Enter the External Port range of the service you are using. For example, if you want to host Unreal Tournament (UT), you would enter the range 7777 to 27900. 4. Check the protocol you will be using, TCP and/or UDP. 5. Enter the IP address of the computer or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. 6. Check the Enable option for the port services you want to use. Consider the example below: Customized Application UT Halflife PC Anywhere VPN IPSEC External Port 7777 to 27900 27015 to 27015 5631 to 5631 500 to 500 TCP UDP IP Address 192.168.1.100 192.168.1.105 192.168.1.102 192.168.1.100 Enable When you have completed the configuration, click the Save Settings button. 8. I can’t get the Internet game, server, or application to work. Appendix A: Troubleshooting Common Problems and Solutions 80 Wireless-G ADSL Gateway with 2 Phone Ports If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one computer to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words, data that enters the Gateway will be checked first by the forwarding settings. If the port number that the data enters from does not have port forwarding, then the Gateway will send the data to whichever computer or network device you set for DMZ hosting.) • Follow these steps to set DMZ hosting: 1. Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the Gateway. Go to the Applications and Gaming => DMZ tab. Click Enabled and enter the IP of the computer. 2. Check the Port Forwarding pages and disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time. • Once completed with the configuration, click the Save Settings button. 9. I forgot my password, or the password prompt always appears when I am saving settings to the Gateway. • Reset the Gateway to factory default by pressing the Reset button for 10 seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps: 1. Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the Gateway. Enter the default username and password admin, and click the Administrations => Management tab. 2. Enter a different password in the Gateway Password field, and enter the same password in the second field to confirm the password. 3. Click the Save Settings button. 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. If you have proxy settings, you need to disable these on your computer. Because the Gateway is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the network. • For Microsoft Internet Explorer 5.0 or higher: 1. Click Start, Settings, and Control Panel. Double-click Internet Options. 2. Click the Connections tab. 3. Click the LAN settings button and remove anything that is checked. 4. Click the OK button to go back to the previous screen. 5. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users. • For Netscape 4.7 or higher: Appendix A: Troubleshooting Common Problems and Solutions 81 Wireless-G ADSL Gateway with 2 Phone Ports 1. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies. 2. Make sure you have Direct connection to the Internet selected on this screen. 3. Close all the windows to finish. 11. To start over, I need to set the Gateway to factory default. Hold the Reset button for 10 seconds and then release it. This will return the Internet settings, password, forwarding, and other settings on the Gateway to the factory default settings. In other words, the Gateway will revert to its original factory configuration. 12. I need to upgrade the firmware. In order to upgrade the firmware with the latest features, you need to go to the Linksys international website and download the latest firmware at www.linksys.com/international. • Follow these steps: 1. Go to the Linksys international website at http://www.linksys.com/international and select your region or country. 2. Click the Products tab and select the Gateway. 3. On the Gateway’s webpage, click Firmware, and then download the latest firmware for the Gateway. 4. To upgrade the firmware, follow the steps in the Administration section found in Chapter 4: Configuring the Gateway. 13. The firmware upgrade failed, and/or the Power LED is flashing. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Power LED stop flashing: • If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open the pdf that was downloaded along with the firmware and TFTP program, and follow the pdf’s instructions. • Set a static IP address on the computer; refer to “Problem #1, I need to set a static IP address.” Use the following IP address settings for the computer you are using: IP Address: 192.168.1.50 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 • Perform the upgrade using the TFTP program or the Gateway’s web-based utility through its Administration tab. 14. My DSL service’s PPPoE is always disconnecting. PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a period of inactivity, just like a normal phone dial-up connection to the Internet. • There is a setup option to “keep alive” the connection. This may not always work, so you may need to reestablish connection periodically. Appendix A: Troubleshooting Common Problems and Solutions 82 Wireless-G ADSL Gateway with 2 Phone Ports 1. To connect to the Gateway, go to the web browser, and enter http://192.168.1.1 or the IP address of the Gateway. 2. Enter the username and password, if asked.

Click the Status tab, and click the Connect button. 5. You may see the login status display as Connecting. Press the F5 key to refresh the screen, until you see the login status display as Connected. 6. Click the Save Settings button to continue. • If the connection is lost again, follow steps 1- 6 to re-establish connection. 15. I can’t access my e-mail, web, or VPN, or I am getting corrupted data from the Internet. The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set automatically. • If you are having some difficulties, perform the following steps: 1. To connect to the Gateway, go to the web browser, and enter http://192.168.1.1 or the IP address of the Gateway. 2. Enter the username and password, if asked. (The default username and password is admin.) 3. Look for the MTU option, and select Manual. In the Size field, enter 1492. 4. Click the Save Settings button to continue. • If your difficulties continue, change the Size to different values. Try this list of values, one value at a time, in this order, until your problem is solved: 1462 1400 1362 1300 16. The Power LED flashes continuously. The Power LED lights up when the device is first powered up. In the meantime, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED remains steady to show that the system is working fine. If the LED continues to flash after this time, the device is not working properly. Try to flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using the following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0. 17. When I enter a URL or IP address, I get a time-out error or am prompted to retry. • Check if other computers work. If they do, ensure that your computer’s IP settings are correct (IP Address, Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem. • If the computers are configured correctly, but still not working, check the Gateway. Ensure that it is connected and powered on. Connect to it and check its settings. (If you cannot connect to it, check the network and power connections.) Appendix A: Troubleshooting Common Problems and Solutions 83 Wireless-G ADSL Gateway with 2 Phone Ports • If the Gateway is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is working correctly. You can remove the Gateway to verify a direct connection. • Manually configure the TCP/IP settings with a DNS address provided by your ISP. • Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet. Frequently Asked Questions What is the maximum number of IP addresses that the Gateway will support? The Gateway will support up to 253 IP addresses. Is IPSec Passthrough supported by the Gateway? Yes, it is a built-in feature that is enabled by default. Where is the Gateway installed on the network? In a typical environment, the Gateway is installed between the ADSL wall jack and the network. Does the Gateway support IPX or AppleTalk? No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for network to network connections, but those protocols cannot connect from the Internet to a network. Do the Gateway’s network connections support 100Mbps Ethernet? The Gateway supports 100Mbps over the auto-sensing network ports. What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private network to one public address that is sent out to the Internet. This adds a level of security since the address of a computer connected to the private network is never transmitted on the Internet. Furthermore, NAT allows the Gateway to be used with low cost Internet accounts when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP. Does the Gateway support any operating system other than Windows 98SE, Windows Millennium, Windows 2000, or Windows XP? Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems. Does the Gateway support ICQ send file? Appendix A: Troubleshooting Frequently Asked Questions 84 Wireless-G ADSL Gateway with 2 Phone Ports Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the Gateway. I set up an Unreal Tournament Server, but others on the network cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the network’s computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port. (Port 8080 usually works well but is used for remote admin. You may have to disable this.) Then in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and ServerName to the IP assigned to the Gateway from your ISP. Can multiple gamers on the network get on one game server and play simultaneously with just one public IP address? It depends on which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. How do I get Half-Life: Team Fortress to work with the Gateway? The default client port for Half-Life is 27005. The computers on your network need to have “+clientport 2700x” added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at the same time, even if on the same network (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer. The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do? Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.com/international for more information. If all else fails in the installation, what can I do? Reset the Gateway by holding down the reset button until the Power LED fully turns on and off. Reset your DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available on the Linksys international website, www.linksys.com/international. How will I be notified of new Gateway firmware upgrades? All Linksys firmware upgrades are posted on the Linksys international website at www.linksys.com/international, where they can be downloaded for free. To upgrade the Gateway’s firmware, use the Administration tab of the Appendix A: Troubleshooting Frequently Asked Questions 85 Wireless-G ADSL Gateway with 2 Phone Ports Gateway’s web-based utility. If the Gateway’s Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Will the Gateway function in a Macintosh environment? Yes, but the Gateway’s setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 or higher for Macintosh. I am not able to get the web configuration screen for the Gateway. What can I do? You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet Explorer. Check with your browser documentation, and make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet. What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ Hosting. To get the IP address, see Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter. If DMZ Hosting is used, does the exposed user share the public IP with the Gateway? No. Does the Gateway pass PPTP packets or actively route PPTP sessions? The Gateway allows PPTP packets to pass through. Is the Gateway cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the Gateway. How many ports can be simultaneously forwarded? Theoretically, the Gateway can establish 520 sessions at the same time, but you can only forward 10 ranges of ports. What are the advanced features of the Gateway? The Gateway’s advanced features include Advanced Wireless settings, Filters, Port Forwarding, Routing, and DDNS. What is the maximum number of VPN sessions allowed by the Gateway? The maximum number depends on many factors. At least one IPSec session will work through the Gateway; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs. Appendix A: Troubleshooting Frequently Asked Questions 86 Wireless-G ADSL Gateway with 2 Phone Ports How can I check whether I have static or DHCP IP Addresses? Consult your ISP to obtain this information. How do I get mIRC to work with the Gateway? Under the Port Forwarding tab, set port forwarding to 113 for the computer on which you are using mIRC. Can the Gateway act as my DHCP server? Yes. The Gateway has DHCP server software built-in. Can I run an application from a remote computer over the wireless network? This will depend on whether or not the application is designed to be used over a network. Consult the application’s documentation to determine if it supports operation over a network. What is the IEEE 802.11g standard? It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. What IEEE 802.11b and 802.11g features are supported? The product supports the following IEEE 802.11b and IEEE 802.11g functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What is ad-hoc mode? When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other, peer-to-peer without the use of an access point. What is infrastructure mode? When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a network through a wireless access point. What is roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the computer must make sure that it is the same channel number with the access point of dedicated coverage area. Appendix A: Troubleshooting Frequently Asked Questions 87 Wireless-G ADSL Gateway with 2 Phone Ports To achieve true seamless connectivity, the wireless network must incorporate a number of different functions. Each node and access point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone. Based on that information, the node next selects the right access point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should seek a new one. When a node no longer receives acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it then re-registers, and the communication process continues. What is the ISM band? The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). What is DSSS? What is FHSS? And what are their differences? Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence SpreadSpectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Appendix A: Troubleshooting Frequently Asked Questions 88 Wireless-G ADSL Gateway with 2 Phone Ports Will the information be intercepted while it is being transmitted through the air? WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN offers the encryption function (WEP) to enhance security and access control. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard. What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for the network. How do I reset the Gateway? Press the Reset button on the back panel for about ten seconds. This will reset the Gateway to its default settings. How do I resolve issues with signal loss? There is no way to know the exact range of your wireless network without testing. Every obstacle placed between the Gateway and a wireless computer will create signal loss. Lead glass, metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with the Gateway and your wireless computer in the same room and move it away in small increments to determine the maximum range in your environment. You may also try using different channels, as this may eliminate interference affecting only one channel. I have excellent signal strength, but I cannot see my network. WEP is probably enabled on the Gateway, but not on your wireless adapter (or vice versa). Verify that the same WEP keys and levels (64 or 128) are being used on all nodes of your wireless network. How many channels/frequencies are available with the Gateway? There are eleven available channels, ranging from 1 to 11 (in North America). If your questions are not addressed here, refer to the Linksys international website, www.linksys.com/international.

While the following is a complete list, steps A through E should, at least, be followed: A. Change the default SSID. B. Disable SSID Broadcasts. C. Change the default password for the Administrator account. D. Enable MAC Address Filtering. Appendix B: Important Information for Wireless Products 90 Wireless-G ADSL Gateway with 2 Phone Ports E. Change the SSID periodically. F. Enable WEP 128-bit Encryption. Please note that this will reduce your network performance. G. Change the WEP encryption keys periodically. For information on implementing these security features, please refer to the User Guide. 4. Security Threats Facing Wireless Networks Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking products first listen for “beacon messages”. These messages are decrypted and contain much of the network’s information, such as the network’s SSID (Service Set Identifier) and the IP Address of the network PC or access point. Here are the steps you can take: Change the administrator’s password regularly. With every wireless networking device you use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s password regularly. SSID. There are several things to keep in mind about the SSID: A. Disable Broadcast B. Make it unique C. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast the SSID. Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use. Change your SSID regularly so that any hackers who have gained access to your wireless network will have start from the beginning in trying to break in. Appendix B: Important Information for Wireless Products 91 Wireless-G ADSL Gateway with 2 Phone Ports MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address. WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a panacea for wireless security concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job more difficult. There are several ways that WEP can be maximized: A. Use the highest level of encryption possible B. Use a “Shared” Key C. Use multiple WEP keys D. Change your WEP key regularly Implementing encryption will have a negative impact on your network’s performance. If you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer.
