Configuration and Management 3.3.2 Network Name All clients on the local wireless network share a common Service Set IDentifier (SSID) or network name. This name is required to establish connection between the Ericsson W3x and the wireless client(s), and to distinguish the wireless network from any other(s) that may be in use nearby. Only devices configured with the same network name as the one set on the Ericsson W3x can obtain access to it. Figure 15 – Wireless LAN: Network Name (SSID) page The network name is case-sensitive (distinguish between uppercase and lowercase letters) and can be changed to any combination of numbers (0 – 9), letters (a – z), and hyphens (-) with a maximum length of 32 characters. If the “Enable SSID broadcast” option is selected, your local wireless client(s) will find the network name when scanning the air. If not, the network name is hidden and has to be manually provided to the wireless client(s). If you want to change the preconfigured network name (MBR), type a new name in the “Network name (SSID):” field and also select if the SSID shall be hidden or not. Click Next to proceed. 3.3.3 Wireless LAN Authentication All communication on the wireless LAN can be protected from potential intruders and eavesdroppers through standard authentication and encryption methods. 22 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management Authentication is used to restrict access to the wireless network and encryption is the translation of data into a form that cannot be easily understood by unauthorized users. The encrypted data can only be sent and received by users with access to a private encryption key. Note: Make sure that the operating system(s) and Wireless LAN interface(s) of the wireless client(s) support the selected authentication method. Figure 16 – Wireless LAN: Authentication page Select one of the authentication methods from the “Authentication” drop-down list. The available options are as follows: • Open (No security); f you select “Open” as authentication method no client configuration is needed but be aware of that the WLAN will now be open without any kind of security. • WEP-64, WEP-128 (Low security); WEP (Wired Equivalent Privacy) is considered to be a low security option. WEP encrypted data is translated into blocks of either 64 bits length or 128 bits length. • WPA, WPA2 (High security); WPA (Wi-Fi Protected Access) and its successor WPA2 are the most reliable security options. WPA encryption uses the Temporal Key Integrity Protocol (TKIP) while WPA2 encryption follows the Advanced Encryption Standard (AES). AES offers a higher level of security and is approved for sensitive corporate and government data transmission. 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 23
Configuration and Management • WPA/WPA2 Mixed (High security) WPA/WPA2 Mixed enables connection of both WPA and WPA2 clients.

Configuration and Management Table 13 - LAN page description Text Description The LAN IP address of the Ericsson W3x. IP address: The subnet mask, which determines the range of IP addresses on the subnet. Subnet mask: The LAN IP address and subnet mask can be changed, but before you do this, consider the following: • Make sure that the new address is not included in the DHCP server IP address range, displayed in the “DHCP Server” section. The default range is 192.168.1.2 – 192.168.1.100. • Make sure that the DHCP server IP address range is included in the new subnet. If you want to change the subnet not to include the DHCP IP address range, you first have to disable the DHCP server. • If port forwarding rules have been configured, those settings have to be removed before changing the IP address or subnet mask. For information, see section 3.7.3 – Port Forwarding. To change the LAN IP address or subnet mask of the Ericsson W3x, type the new values in the corresponding fields and click Apply to save the settings. Note: If you change the LAN IP address while connected to the WUI, you will be disconnected. You have to redirect the web browser to the new address in order to confirm the new settings. Type the new LAN IP address in the Address (URL) field and press Enter. 3.5.2 DHCP Server The Ericsson W3x incorporates a DHCP (Dynamic Host Configuration Protocol) server which dynamically assigns IP addresses to devices on the LAN/WLAN whenever they are switched on. The DHCP server also puts the hostname, supplied by the client DHCP request, in the local DNS (Domain Name System/Service) proxy. The DNS proxy contains a small database of local host names and addresses supplied by client DHCP requests. In addition it also caches requests to remote DNS servers. The following configuration options are displayed in the “DHCP server” section on the LAN page: 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 37
Configuration and Management Table 14 - DHCP Server configuration options Text Description Select this checkbox to enable the DHCP server. Enable DHCP server Note: If you already have a DHCP server on your network, you should disable this feature in the Ericsson W3x. IP address range from: The IP addresses that can be assigned to LAN/WLAN clients are collected from a predefined range of available IP addresses. The preconfigured range – from 92.168.1.2 to 192.168.1.100 is suitable for most local networks. IP address range to: The DHCP server uses the concept of a “lease”, that is the amount of time that a given IP address will be valid for a specific device. If the lease time expires and the device is still connected, the lease is automatically renewed. Lease Time [sec]: The preconfigured lease time is 7200 seconds (2 hours) and a valid value must be within the range 60 and 2147483647 seconds. Note: If you want to configure a connected device with a static IP address, make sure that the address is outside the DHCP server IP address range. Before changing any of the DHCP server settings, read the following: • The DHCP server IP address range has to be on the same subnet as the LAN IP address on the Ericsson W3x. • The DHCP server IP address range must not include the LAN IP address on the Ericsson W3x. • If port forwarding rules have been created, those settings have to be removed before changing the DHCP server IP address range.

Configuration and Management 3.6 Wireless LAN A Wireless LAN (WLAN) is a local network that communicates through wireless connections. The Ericsson W3x can be used as a WLAN Access Point (AP), connecting to wireless PCs according to the IEEE standard 802.11b/g, providing Internet and LAN access. The WLAN settings are displayed on the Wireless LAN page. Figure 35 - Wireless LAN page 3.6.1 Enable WLAN To enable the wireless LAN on the Ericsson W3x select the “Enable WLAN” check box and click the Apply button to save the setting. To ensure the security of your Wireless LAN, you are recommended to change the default settings for SSID and authentication. Note: The wireless setup typically requires configuration of both the Ericsson W3x and the wireless client(s). For more information on configuration of wireless clients, see section 6.2 – Wireless LAN Settings. 40 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management 3.6.2 Region Wireless devices are thoroughly regulated and the countries have slightly different regulations. Therefore, the geographical region where the Ericsson W3x is used must be stated to make sure the correct radio frequencies are used when transmitting data. Select the geographical region in which you reside from the “Region” drop-down list and click Apply to save the setting. 3.6.3 Radio Channel The radio channel must be in accordance with the previous set region and only channels that are allowed in the configured region are available in the “Radio channel” drop-down list. By selecting “Auto” (recommended) the radio in the Ericsson W3x will automatically scan each valid channel and choose the one with least interference. Select either “Auto” or a specific channel number from the “Radio channel” drop-down list and click Apply to save the setting. 3.6.4 Transmit Power [dBm] To avoid interference with other wireless networks, the transmit power level can be reduced. If you want to change the transmit power level according to your specific conditions, select an appropriate level from the “Transmit power [dBm]” drop-down list and click Apply to save the setting. 3.6.5 Data Rate According to wireless LAN standards and the IEEE 802.11 protocols there are different data rates available for different modes. From the “Data rate” drop down list there are the following modes available: • B-Mode Only (supporting IEEE 802.11b clients with a maximum data rate of 11 Mbit/s) • G-Mode Only (supporting IEEE 802.11g clients with a maximum data rate of 54 Mbit/s) • B/G-Mixed Mode (supporting both IEEE 802.11b/g clients as described above) • Legacy B-Mode (supporting IEEE 82.11b legacy clients). 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 41

Configuration and Management 3.6.7 Network Name (SSID) All clients on the WLAN share a common network name or SSID (Service Set IDentifier). This name is required to establish connection between the Ericsson W3x and other wireless client(s) and to distinguish the WLAN from any other(s) that may be in use nearby. Only clients configured with the same network name (SSID) as the one set on the Ericsson W3x can obtain access to it. Note: It is recommended to change the preconfigured network name “MBR” to something else that makes it harder for unauthorized persons to access your wireless network. The following settings concerning the network name are displayed and can be modified on the Wireless LAN page: Table 16 - Network name description Text Description The network name (SSID) of the wireless network. Network name (SSID): The network name is case-sensitive (distinguish between uppercase and lowercase letters) and can be changed to any combination of numbers (0-9), letters (a-z), and hyphens (-) with a maximum length of 32 characters. If “Enable SSID broadcast” is checked, the SSID is continuously broadcasted and any nearby wireless client(s) will find it when scanning the air. Enable SSID broadcast If the checkbox is cleared, the SSID will be hidden and in this case the name has to be provided manually to every wireless client where access is to be granted. To change settings for the Network Name (SSID), type the new values in the corresponding fields and click Apply to save the settings. 3.6.8 WLAN Security All communication on the wireless network can be protected using different authentication and encryption methods. The most common is to encrypt the WLAN using an encryption method such as WEP, WPA and WPA2. 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 43
Configuration and Management Which authentication and encryption method that should be used depends on what is supported by the connected wireless client(s). Note: Each wireless client must be configured to use exactly the same security mode and key/passphrase as the Ericsson W3x or they will not be able to connect. In the “Authentication” drop-down list you select which type of authentication/encryption you want to use for your WLAN. The following subsections describe the authentication methods supported by the Ericsson W3x. 3.6.8.1 Open (No security) If you select “Open” as authentication method no client configuration is needed but be aware of that the WLAN will now be open without any kind of security. For example, it is now possible for anyone with a computer and a wireless interface card to connect to the Ericsson W3x at any time and having access to both your home network and Internet connection. 3.6.8.2 WEP and WEP Encryption Key (Low security) WEP (Wired Equivalent Privacy) is considered to be a low security option. The data is encrypted into blocks of either 64 bits length or 128 bits length. WEP encrypted data can only be sent and received by users with access to a private encryption key. This means that each client on your wireless network has to be manually configured with exactly the same key as the one entered in the Ericsson W3x in order to allow encrypted data transmissions. • WEP-64 bit data encryption requires a key including 10 characters. Only hexadecimal numbers 0-9 and letters a-f (uppercase or lowercase) are allowed. • WEP-128 bit data encryption requires a key including 26 characters. Only hexadecimal numbers 0-9 and letters a-f (uppercase or lowercase) are allowed. Enter an encryption key in the “Passphrase / Key” field and click Apply to save the settings. 3.6.8.3 WPA/WPA2 and Passphrase (High security) WPA (Wi-Fi Protected Access) and its successor WPA2 are the most reliable security options. WPA encryption uses the TKIP (Temporal Key 44 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management Integrity Protocol) while WPA2 encryption follows AES (Advanced Encryption Standard). AES offers a higher level of security and is approved for sensitive corporate and government data transmission. WPA/WPA2 Mixed enables connection of both WPA and WPA2 clients. WPA and WPA2 authentication and encryption require a passphrase. A passphrase is a sequence of words or other text and is similar to a password in usage, but is generally longer for added security. Each client on your wireless network has to be configured with exactly the same passphrase as the one entered in the Ericsson W3x in order to allow encrypted data transmission. A WPA or WPA2 passphrase is case sensitive (distinguish between uppercase and lowercase letters) and consists of between 8 and 63 characters. It is recommended that the passphrase contains at least 20 characters. Enter a passphrase in the “Passphrase / Key” field and click Apply to save the settings. Note: Avoid using special characters (such as :, “ and ¤) when entering a passphrase. 3.6.9 Connected Devices The “CONNECTED DEVICES” list on the Wireless LAN page includes the MAC (Media Access Control) addresses of all wireless clients currently connected to the Ericsson W3x. 3.6.10 Whitelist A common method of restricting WLAN access is to specify the MAC address(es) in a “whitelist” for those computers to be granted access to the WLAN. This kind of whitelist is also known as “MAC Association” or “MAC Access list”. Up to 20 MAC addresses for wireless clients can be added to the whitelist. Once the whitelist has been enabled, only clients with an associated MAC address are allowed to connect to the WLAN. Note: This feature does not require any configuration of clients, but it is recommended that some kind of encryption (WEP, WPA/WPA2) is used in combination with the whitelist. 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 45
Configuration and Management 3.6.10.1 Add Client(s) to the Whitelist To add a client to the whitelist, you can either copy/paste a MAC address from the “CONNECTED DEVICES” list or type the client’s MAC address in the field below “WHITELIST” and click Add . The MAC address has the form of xx:xx:xx:xx:xx:xx, where x is a hexadecimal number (0-9 and/or letters a-f), for example 00:80:37:8c:10:46. Check “Enable whitelist” to activate the feature and click Apply to save the settings. To delete a MAC address from the whitelist, click the Delete button next to the MAC address to delete. 3.6.10.2 Find a Wireless Client MAC Address The MAC address for a WLAN adapter is normally found on the product label. For internal wireless PCI cards running on Windows platform, the command ipconfig /all (run from a Command Prompt window) can be used to display the MAC address (displayed as “Physical Address” against the network adapter). For example: Wireless LAN adapter Wireless Network Connection: Media State . . . . . . . . . . . : Connected Description . . . . . . . . . . . : Intel(R) PRO/Wireless 3945ABG Physical Address. . . . . . . . . : 00-19-D2-39-14-54 DHCP Enabled . . . . . . . . . . .: Yes Autoconfiguration Enabled . . . . : Yes 46 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management 3.7 NAT The Ericsson W3x includes a NAT (Network Address Translation) service. With this service several computers on a LAN/WLAN can share the same Internet connection using a single public IP address. Devices on the LAN/WLAN use dedicated private IP addresses, which cannot be used on the Internet. When a computer on the LAN/WLAN want to send a data package to the Internet, its IP address is automatically translated by NAT to an external (public) IP address allowed on the Internet. When a reply receives to this external IP address, it is translated back to the origin private IP address to be able to found its way back to the sending computer on the LAN/WLAN. In this way, details about the local devices remain private and it is not possible to access a local computer on the LAN/WLAN directly from the Internet. The NAT page includes the following settings: Figure 37 - NAT page 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12 47
Configuration and Management 3.7.1 UPnP IGD The Ericsson W3x supports the Universal Plug and Play (UPnP) Internet Gateway Device (IGD) standard. UPnP IGD is used to provide automatic port forwarding allowing communication between certain Internet applications and the local network. When UPnP IGD is enabled, programs like MSN Messenger® and most network enabled games are allowed to pass the NAT service. UPnP IGD is enabled by default, but if you want to disable the feature, clear the “Enable UPnP IGD” check box and click Apply to save the settings. 3.7.2 Application Level Gateways From a security perspective, certain Internet applications, for example FTP applications that open additional ports upon transfer, are especially problematic to handle. An Application Level Gateway (ALG) provides a translation and transportation service for such a specific application. Incoming data packets are checked against existing NAT and packet filtering rules, IP addresses are evaluated and a detailed packet analysis is performed. If necessary, the contents of a packet are modified and if a secondary port is required, the ALG will open one. The Ericsson W3x includes ALG support for the following applications: Table 17 - ALG Supported Applications Application Protocol Port number File Transfer Protocol (FTP) TCP 21 Trivial File Transfer Protocol (TFTP) UDP 69 Point-to-Point Tunneling Protocol (PPTP) TCP/UDP 1723 Session Initiation Protocol (SIP) TCP/UDP 5060 Real Time Streaming Protocol (RTSP) TCP/UDP 554 The ALG for each application does not require additional configuration. The supported ALGs can be enabled and disabled individually. To disable an ALG, clear the corresponding check box and click Apply to save the settings. 48 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management 3.7.3 Port Forwarding Port forwarding is used to allow an external user to access a service residing on a server connected to the LAN (to cross the NAT border). It enables access to servers on the LAN from the Internet (e.g. Web server) and also enables applications to work from the LAN (e.g. games, voice and chat) to the Internet. Note: Port forwarding requires that the Ericsson W3x has a public IP address for Port Forwarding requests from the Internet to be handled correctly. This IP address is displayed on the Overview page as the “Internet: IP address”. A private IP address usually begins with 10, 172, or 192. In this case, no incoming access from the Internet is allowed. For more information on public and private IP addresses, contact your service provider. When a computer on the Internet sends data to the public IP address of the Ericsson W3x, it needs to know what to do with the data. A port forwarding rule tells the Ericsson W3x which computer on the local area network to send the data to. The “PORT FORWARDING” section on the NAT page includes the following information about port forwarding rules: Table 18 - Port Forwarding description Text Description NAT Port The NAT port number that the data traffic is allowed to be transported on. The IP address of the destination server on the LAN. Server IP The port number on the destination server which identifies the type of service that is directed, for example web service on port 8080. Server Port The protocol to be used for the service; TCP or UDP. Protocol Click on the button to delete the port forwarding rule. Delete Click on the button to edit the port forwarding rule.

Below are some examples of common applications and corresponding server port they use for network access. The “NAT Port” has often the same value as the “Server Port” value. Exceptions are made when the same applications are used on many clients on the LAN/WLAN, where each “Server IP” value needs to be unique and differ from the “NAT Port” value. Table 19 - Common applications server ports Application Server Port MSN Messenger® 6901 Unreal Tournament 2004® 7777, 7778, 7787, 28902 NetMeeting® 1720, 1503 Quake III® 27669 (+1 for each player) Note: If multiple ports or port ranges are required, create a new port entry for each port or port range. 3.7.3.2 Port Forwarding Example In the following example, port forwarding is used to allow incoming access (from the external network (Internet)) to an internal web server (on the LAN/WLAN). The TCP protocol is used for data traffic. The NAT port 80 on the Ericsson W3x is open and the destination computer on the LAN with static server IP address 192.168.1.101 has appointed the server port 8080 to be used. 50 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12

Configuration and Management 3.8 File and Printer Sharing The Ericsson W3x supports local network storage and printer sharing through the USB port. If an external USB hub is connected, the Ericsson W3x supports connection of up to two storage devices and one printer at the same time. The Sharing page displays information about connected USB device(s): Figure 41 - Sharing page 3.8.1 How it Works The Ericsson W3x uses Samba (www.samba.org) as the base to implement file and printer sharing through SMB/CIFS. SMB and CIFS are the protocols used by Microsoft for sharing and the service is called “smb” on the Ericsson W3x. • Linux Kernel auto detection of USB devices is used as part of the automatic configuration of the storage and printer sharing. When a new USB device (storage or printer) is detected, the Ericsson W3x automatically creates configuration files for Samba containing the new device. It then makes the smb service use the new configuration, 52 1/1551-CRH 102 168 Uen Rev PA2 2008-11-12
Configuration and Management thereby sharing the USB device via the SMB/CIFS protocol. This process is totally automatic and there are no configuration parameters that can be set, other than renaming the shared resources. The Ericsson W3x uses a relatively low powered processor and is not designed to be a multi tasking platform. This means that you may experience problems during high load situations such as simultaneously downloading a large file through the mobile network and printing a large document or copying a large file to/from a shared storage device mounted on the Ericsson W3x. Don’t expect to have full performance on all simultaneous tasks. 3.8.1.1 Safe Removal of a USB Device Before removing a USB device from the Ericsson W3x wait until the activity LED (if any) on the device stops blinking or wait some 30 seconds to be sure there is not any ongoing/remaining write operations to be made. 3.8.2 Host Name and Workgroup All devices on the LAN/WLAN that want to access a USB shared storage device or printer must belong to the same workgroup as the Ericsson W3x. The following information can be changed on the Sharing page: Table 20 - Sharing information Text Description The name of the Ericsson W3x on the local network.

TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. SSID – Service Set Identifier A unique network name, or identifier, that differentiates one wireless LAN from another. All access points and clients attempting to connect to a specific WLAN must use the same SSID. Subnet A portion of a network. The subnet is distinguished from the larger network by a subnet mask that selects some of the computers of the network and excludes all others. The subnet’s devices remain physically connected to the rest of the network, but they are treated as though they were on a separate network. UDP – User Datagram Protocol A connection-less transport service that dispenses with the reliability services provided by TCP. UDP gives applications a direct interface with IP and the ability to address a particular application process running on a host via a port number, without setting up a connection session.
