Introduction to GlobeSurfer 3G
Welcome to the third generation wireless network. By combining a wireless router following the 802.11 b/g WLAN standard with a 3G UMTS Gateway the GlobeSurfer 3G presents a new style of wireless freedom.
The GlobeSurfer 3G is a 802.11b/g wireless router and Internet gateway that provides Internet access for homes and small offices over the 3G UMTS net­work. By connecting laptops and stationary computers with either WLAN or Ethernet to the GlobeSurfer 3G you will get Internet access with a speed similar to a fixed DSL connection. And while sharing the wireless Internet connection you will also be able to share the resources of the local computers connected to the GlobeSurfer 3G.
GlobeSurfer 3G is easy to install and use. Yet it provides advanced network­ing functions and security functions that can be configured with a web-based management interface. Its small attractive design and powerful built-in func­tionality makes your Internet surfing easy and secure in any location with 3G access and a power outlet.
Some of the attractive features of the GlobeSurfer 3G:
• WAN - UMTS uplink and downlink
• Small attractive design with informative display
• Sends and receives SMS
• WLAN according to 802.11 b/g for maximum compatibility
• Ethernet connection for stationary computers
• Built-in firewall to protect against hacker attacks

1.1 About This Manual
This manual describes configuration and operation of the GlobeSurfer 3G. It is intended as a complement to the GlobeSurfer 3G User Guide to provide ref­erence information for the advanced user of the GlobeSurfer 3G. It is assumed that the hardware installation of the GlobeSurfer 3G has been done when the Reference Manual is read.
This version of the manual is valid for GlobeSurfer 3G version 3.15.4 R2H. Other product versions with customer specific functions not described in this manual, may be available.

Figure 1.2: Hardware Configuration
1.2 Basic Setup
Connecting your computer or local network to the GlobeSurfer 3G is a simple procedure, varying slightly depending on your operating system. The setup is designed to seamlessly integrate GlobeSurfer 3G with your computer or local network.
The Windows default network settings will in most cases make the setup pro­cedure described below unnecessary. For example, the default DHCP setting in Windows is client, requiring no further modification.
However, it is advised to follow the setup procedure described below to verify that all communication parameters are valid and that the physical cable con­nections are correct.
The basic setup procedure consists of three consecutive configuration steps (Please refer to figure 1.2):
1. Setting up LAN and WAN connections [1.3]
2. PC network configuration [1.4]
3. GlobeSurfer 3G Quick Setup [1.5]
1.3 Step 1 - Setting up LAN and WAN Connections
1.3.1 LAN Connection
Your computer can connect to the GlobeSurfer 3G either with a fixed cable connection or with a wireless connection.
If you want to use a fixed connection, connect a standard Ethernet RJ-45 cable (Category 5) between the LAN socket on the GlobeSurfer 3G and the corre­sponding Ethernet LAN port of your PC network card. Consult the GlobeSurfer 3G User Guide for more information about the LAN port.

Page 12
If you want to use a wireless connection, according to the 802.11 b/g WLAN standard, follow the instructions from the supplier of your WLAN adapter card, or your PC if the WLAN adapter is built into the PC.
1.3.2 WAN Connection
Setting up the WAN connection requires that a SIM card is inserted correctly into the SIM slot of the GlobeSurfer 3G. See the User Guide for instructions on how to insert the SIM card. With the SIM card in place you configure the WAN connection through the Quick Setup of the GlobeSurfer 3G (see section 1.5. The first time you login to the GlobeSurfer 3G you will have to enter a PIN code. The PIN code is received from your ISP, but normally provided separately from the SIM card for security reasons.
1.4 Step 2 - PC Network Configuration
The GlobeSurfer 3G provides a DHCP server, which means that each computer connected to the LAN can obtain its network addresses – IP address and DNS server IP addresses – automatically from the GlobeSurfer 3G. This is the de­fault setting in Windows and valid in most cases. Alternatively, each network interface on the LAN PCs can be configured with a statically defined IP ad­dress and DNS address. If this is the case you must receive valid addresses from your network operator and configure your PC and the GlobeSurfer 3G accordingly. Then refer to section 4.2.
Figure 1.3 displays the TCP/IP Properties dialog box as it appears in Windows XP. These properties are available on all operating systems but are accessed slightly differently on each operating system.

Figure 1.6: Quick Setup
1.5.1 UMTS Setup
Check or change the following settings on the Quick setup screen to configure the UMTS connection:
Access point name: Enter the access point name as provided by your Internet Service Provider (ISP), or accept the name already set.
7
Page 16
Connect automatically: To automatically set up a UMTS connection when data is about to be sent or received, select Automatically. If Manually is se­lected, you must press the Connect button on the GlobeSurfer 3G each time a connection is required.
Inactivity timeout: There is normally no need to change the default value of 10 minutes. Set it to zero (0) if you don’t want the UMTS connection to disconnect automatically at all. The maximum value is 1440 minutes (24 h). The inactivity timeout is not affected by incoming traffic.
1.5.2 Wireless Setup
The following settings are the most important to set up for the local Wireless LAN:
SSID: The Service Set Identifier (SSID) is the name of the specific wire­less network. Enter a name that you want to use as an identifier of your specific local wireless network (maximum 32 characters).
SSID broadcast: When this checkbox is set to Enabled the GlobeSurfer 3G will broadcast the SSID on your wireless network. This will allow unau­thorized devices from detecting your SSID and attempting to connect to your network. De-select the checkbox to disable broadcasting of the SSID. Disabling SSID broadcast will hide the name of the network from other wireless devices. This provides a very basic form of security. Other devices will still be able to connect, provided that they are supplied with the SSID. A recommendation is to install your wireless network with this feature enabled and then disable it once you have set up the GlobeSurfer 3G and any wireless clients.
Encryption: With No encryption selected, anyone with a Wireless PC can eavesdrop on your network. No encryption should only be used during installation of your network to simplify the setup procedure. Select WEP encryption or WPA encryption once your local wireless network has been set up. See below for instructions on how to set the encryption type.
1.5.2.1 Encryption
The GlobeSurfer 3G supports two types of encryption:
WEP: Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption method with user configurable fixed keys. However, only 40/104 bits are effectively used.
WPA: Wi-Fi Protected Access (WPA) is a 256 bit encryption method with keys that change over time.
Note: WPA provides a higher level of security, provided by its longer key and dynamic changes made to the key over time. Use WPA with any clients that support it. If you enable encryption on the GlobeSurfer 3G, you must configure your wireless PCs to use exactly the same encryption type and keys, otherwise the devices will not understand each other. The encryption secures the wire­less communication between GlobeSurfer 3G and its wireless clients. Enabling
8
Page 17
encryption has no security effect on data transmitted through wired (Ethernet) connections.
• Configuring WEP:
There are two levels of WEP encryption available, 64 bit and 128 bit. Se­lect the desired level. Enter the pre-shared key in either hexadecimal (0-9, A-F) format, 10 or 26 characters, or plain text (ASCII) format, 5 or 13 characters.
• Configuring WPA:
With WPA there is only one level of encryption available. Enter the pre­shared key, either as a 256 bit series of hexadecimal digits (64 characters) or as a plain text (ASCII) pass-phrase (at least 8 characters).
Note: A plain text string is much easier to remember than hex keys, but it may be easier to crack. Also note that the ASCII-text format may not be supported by all wireless devices, since different manufacturers have developed different ways of converting plain text. If you are experiencing difficulty, the hex key format is supported by most vendors.
1.5.3 Firewall Setup
The GlobeSurfer 3G firewall has three pre-defined levels of security. As default the typical security is set, which blocks all traffic that has been initiated by an external (Internet) source, and allows all traffic that has been initiated from your local network.
Note: It is the origin of the request, not subsequent responses to this request, that determines whether the incoming or outgoing traffic is allowed or blocked.
To learn more about how to configure your firewall security parameters, please refer to Section 5. If you wish to apply corporate-grade security to your net­work refer to Section 5.11.
1.6 Additional Network Configuration
GlobeSurfer 3G does not require further configuration in order to start work­ing. After the setup described in this chapter, you can immediately start using the GlobeSurfer 3G to:
• Build a local network by connecting additional PCs and network devices to the GlobeSurfer 3G.
• Share the Internet connection among multiple users and between all of the computers connected to your local network.
• Share resources like file servers, printers, etc. between computers in the local network.
• Control network parameters to, for example, set up Virtual Private Net­works, LAN bridges and configure the security settings.
• View network status, traffic statistics, system log and more.

4.1.3 PPP Authentication
Point-to-Point Protocol (PPP) currently supports four authentication protocols: Password Authentication Protocol (PAP), Challenge Handshake Authentica­tion Protocol (CHAP), and Microsoft CHAP version 1 and 2.
Please note that encryption is performed only if Microsoft CHAP, Microsoft CHAP version 2, or both are selected.
Figure 4.4: PPP Authentication Settings
Login username As agreed with ISP.
Login password As agreed with ISP.
Support unencrypted password (PAP) Password Authentication Protocol (PAP)
is a simple, plaintext authentication scheme. The user name and pass­word are requested by your networking peer in plaintext. PAP, how­ever, is not a secure authentication protocol. Man-in-the-middle attacks can easily determine the remote access client’s password. PAP offers no protection against replay attacks, remote client impersonation, or remote server impersonation.
Support Challenge Handshake Authentication (CHAP) The Challenge Hand-
shake Authentication Protocol (CHAP) is a challenge-response authenti­cation protocol that uses MD5 to hash the response to a challenge. CHAP protects against replay attacks by using an arbitrary challenge string per authentication attempt.
Support Microsoft CHAP Select this check box if you are communicating with
a peer that uses Microsoft CHAP authentication protocol.

Routing Mode When Advanced routing is selected, select one of the f ollowing
Routing modes:
Route Use route mode if you want your GlobeSurfer 3G to function as
a router between two networks.
NAT Network Address Translation (NAT) translates an IP address to a
valid, public address on the Internet. This adds security since in­ternal LAN addresses are not transmitted over the Internet. In ad­dition, NAT allows many addresses to exist behind a single valid address. Use the NAT routing mode if your LAN consists of a sin­gle device, otherwise collisions may occur if more than one device attempts to communicate using the same port.
NAPT Network Address and Port Translation (NAPT) refers to network
address translation involving the mapping of port numbers, allow­ing multiple machines to share a single IP address. Use NAPT if your LAN encompasses multiple devices, a topology that necessi­tates port translation in addition to address translation.

4.3.3.3 MAC filtering settings
MAC filtering mode A common method of restricting WLAN network access
is to specify the Media Access Control (MAC) address of computers that are allowed or denied access to your network. Every WLAN network adapter is identified by a unique MAC address. The GlobeSurfer 3G sup­ports MAC filtering based on either a list of denied or allowed comput­ers. MAC filtering mode Allow specifies that the list of MAC addresses is granted access to GlobeSurfer 3G. MAC filtering mode Deny specifies that all computers except those in the list of MAC addresses are granted access to GlobeSurfer 3G. Select Disable if you want to disable MAC fil­tering.
MAC filtering settings Click the New MAC address link to define MAC ad-
dresses to filter. The selected MAC filtering mode will be performed on the corresponding network adapters.

intercept Wireless-G and 802.11b transmissions. Conversely, CTS protec­tion mode decreases performance. Leave this feature disabled unless you
48
Page 57
encounter severe communication difficulties between the GlobeSurfer 3G and Wireless-G products.
Beacon interval A beacon is a packet broadcast by GlobeSurfer 3G to syn-
chronize the wireless network. The beacon interval value indicates how often the beacon is sent.
DTIM interval The Delivery Traffic Indication Message (DTIM) is a count-
down value that informs wireless clients of the next opportunity to re­ceive multicast and broadcast messages. This value ranges between 1 and 16384.
Fragmentation threshold Packets that are larger than this threshold are frag-
mented into multiple packets. Try to increase the fragmentation thresh­old if you encounter high packet error rates. Do not set the threshold too low, since this can result in reduced networking performance.
RTS threshold GlobeSurfer 3G sends Request to Send (RTS) packets to the
wireless client in order to negotiate the dispatching of data. The wire­less client responds with a Clear to Send (CTS) packet, signaling that transmission can commence. In case packets are smaller than the pre­set threshold, the RTC/CTS mechanism is not active. If you encounter inconsistent data flow, try a minor reduction of the RTS threshold size.

4.6.2.2 PPP Settings
Point-to-Point Protocol (PPP) is the most popular method for transporting pack­ets between the user and the Internet service provider. PPP supports authen­tication protocols such as PAP and CHAP, as well as other compression and encryption protocols.
L2TP Server Host name and shared secret should be configured according to
your ISP information.
PPP-on-Demand Use PPP on demand to initiate the point-to-point protocol
session only when packets are actually sent over the Internet.
Time between reconnect attempts Specify the duration between PPP recon-
nected attempts, as provided by your ISP.

4.6.2.3 PPP Authentication
Point-to-Point Protocol (PPP) currently supports four authentication protocols: Password Authentication Protocol (PAP), Challenge Handshake Authentica­tion Protocol (CHAP), and Microsoft CHAP version 1 and 2.
Please note that encryption is performed only if Microsoft CHAP, Microsoft CHAP version 2, or both are selected.
Figure 4.94: PPP Authentication Settings
Login username As agreed with ISP.
Login password As agreed with ISP.
Support unencrypted password (PAP) Password Authentication Protocol (PAP)
is a simple, plaintext authentication scheme. The user name and pass­word are requested by your networking peer in plaintext. PAP, how­ever, is not a secure authentication protocol. Man-in-the-middle attacks can easily determine the remote access client’s password. PAP offers no protection against replay attacks, remote client impersonation, or remote server impersonation.
Support Challenge Handshake Authentication (CHAP) The Challenge Hand-
shake Authentication Protocol (CHAP) is a challenge-response authenti­cation protocol that uses MD5 to hash the response to a challenge. CHAP protects against replay attacks by using an arbitrary challenge string per authentication attempt.
Support Microsoft CHAP Select this check box if you are communicating with
a peer that uses Microsoft CHAP authentication protocol.
Support Microsoft CHAP Version 2 Select this check box if you are commu-
nicating with a peer that uses Microsoft CHAP Version 2 authentication protocol.
4.6.2.4 PPP Encryption
PPP supports encryption facilities to secure the data across the network con­nection. A wide variety of encryption methods may be negotiated, although typically only one method is used in each direction of the link.
Please note that PPP encryption can only be used with MS-CHAP or MS-CHAP­V2 authentication algorithms.

if your peer supports 128 bit encryption keys.
4.6.2.5 PPP Compression
The PPP Compression Control Protocol (CCP) is responsible for configuring, enabling, and disabling data compression algorithms on both ends of the point­to-point link. It is also used to signal a failure of the compression/ decompres­sion mechanism in a reliable manner.
Figure 4.96: PPP Compression
For each compression algorithm, select one of the following from the drop down menu:
Reject Reject PPP connections with peers that use the compression algorithm.
Allow Allow PPP connections with peers that use the compression algorithm.
Require Ensure a connection with a peer is using the compression algorithm.
4.6.2.6 Internet Protocol
