Installing the router

Role of the router on the network
A router acts as a connection point between two networks. A router is generally used to connect a local area network with multiple computers to the network of an Internet service provider. In other words, a router allows several computers to share an Internet connection. The Sandberg Wireless G54 Router is wireless, meaning that computers with wireless network cards can connect to it without the use of cables.

Internet

• As the router’s role is to create a bridge between two networks, it has one IP address for each network.
• One IP address represents the router on the Internet and is called the external IP address, and the other represents the router on the local area network and is called the internal IP address.
• Each of the computers on the local area network also has its own IP address.
• This can be allocated automatically by the router (using the router’s DHCP function) or it can be specifi ed manually on each computer.
• 172.64.102.85 is the router’s external IP address.
• When communicating with a computer over the Internet, it will be this address that the computer ‘sees’, regardless of which computer on the local area network is being used.
• The external IP address can either be dynamic or fi xed, depending on the type of subscription set up with the Internet service provider.
• A dynamic IP address is one that is allocated by the Internet service provider, but it is not necessarily the same address all the time. A fi xed IP address always remains the same.
• 192.168.2.1 is the router’s internal IP address. This is the address of the router on the local area network, the one that all the computers on the network connect to in order to access the Internet.
• 192.168.2.100 is the IP address of a computer on the network. This can either be defi ned in Windows or be automatically allocated by the router.
• 192.168.2.101 is the IP address of a computer on the network. This can either be defi ned in Windows or be automatically allocated by the router.

Connecting the router

The router can function both as a router and an access point. The connection mode used with the router depends on how it is intended to function on the network.

• Router – Used if the Internet connection is to be shared between multiple computers, either wirelessly, with cables, or both.
• Access Point – Used if the Internet connection is already shared between multiple computers,
  e. g. via a router, and wireless access to the Internet is required. In this case, the role of the router is to provide wireless access to the existing router.
• Connect the electrical plug to a mains socket and the small round connector on the power lead to the 12VDC socket on the router. Check that the “Power” lamp lights up.
• If you will be using the router function, connect the router’s WAN port to your existing ADSL/broadband connection using a network cable.
• If you will be using the access point function, connect a network cable from the existing network (typically the existing router) to port 1, 2, 3 or 4 on the router.
• Screw the antenna fi rmly into the thread on the far right. The antenna can be folded upwards to increase the signal strength.
• Connect up to four computers to the ports marked 1 to 4 on the router. If you will only be connecting wirelessly, skip this step.
• Start the connected computers.

Positioning and installation of the router

Drill template

• To ensure the best possible wireless signal conditions, the router should be placed centrally in relation to the devices connecting wirelessly to it.
• The package includes an installation kit containing four rubber feet, two screws and two rawlplugs. The rubber feet can be stuck to the base of the router to stand it on a fl at surface.
• If you wish to wall-mount the router, drill two holes in the wall 14 centimetres (5.51 inches) apart.
• At the back of this manual there is a drill template that you can cut out and use to ensure the holes are the correct distance apart.
• On the back of the router there are two sets of brackets, allowing it to be mounted with the connectors facing up or down.

Securing a wireless network
If you are using the router’s wireless functionality, the network must be secured against unauthorised access by enabling one of the router’s built-in security features. This protects authorised network users against unauthorised access from the outside.

The router can use one of the following security features:

• WEP
• WPA pre-shared key
• WPA RADIUS

All computers that connect wirelessly to the router must use the same type of security as the router. It is therefore important to select a security method supported by all the network cards on the network. For more information on this, see the user guide for the individual network cards on the network. For additional security, the MAC Address Filtering function can be used. See section 2.3.4 for information on this. Configuration of the various security features is described in the following sections.

Configuring WEP

• Click [General Setup].
• Click [Wireless], then [Security Settings].
• Under Encryption, select WEP.
• Under Key Length, select the encryption strength. You can select either 64-bit or 128-bit.
  For greatest security, 128-bit is recommended.
• Under Key Format, select the format for entering security codes. You can select either HEX
  (digits and/or letters from A to F) or ASCII (letters and/or digits).
• Under Default TX Key, select the security code to use as default.
• In the fields Encryption Key 1-4, enter up to four security codes. If you enter multiple codes, computers can access the network wirelessly by entering any one of them. The codes must comply with the format given in Key Length and Key Format. Both upper and lower case letters can be used.
  • 64- bit HEX – 10 digits and/or letters from A to F
  • 128-bit HEX – 26 digits and/or letters from A to F 64-bit ASCII – 5 letters and/or digits
  • 128-bit ASCII – 13 letters and/or digits
• Click [Apply].
• Click [Continue] to change more settings or [Apply] to restart the router for the new settings to take effect.

 QoS

• Reserve bandwidth for specifi c web applications.
• Limit bandwidth usage for specifi c web applications.

Quality of Service (QoS) is a function that allows the router to prioritise bandwidth usage so that specifi c services are always guaranteed a certain level. This can be very useful for services such as IP telephony, to ensure that call quality is not diminished when there is heavy network traffi c. QoS can also be used to impose a maximum limit on the bandwidth usage of certain applications.
To use Quality of Service, one or more rules must be set up to defi ne the bandwidth requirements for certain applications.

The router has no direct link to applications on the computer, so the only way to control the applications’ network traffi c is to confi gure rules regulating traffi c on the network ports used by the applications. You therefore need to know which network ports are used by an application before you can set up a Quality of Service rule. The ports an application uses can normally be found in the application’s written documentation or on its website.

QoS menu

The QoS menu contains a list of rules that have been set up. Every rule on the list has a priority (Priority). The rule with the highest priority is allocated bandwidth fi rst, and so on down the list. Network traffi c that is not covered by user-defi ned rules is allocated bandwidth last of all.
NB: If the total bandwidth allocated to user-defi ned rules exceeds the bandwidth the Internet connection can deliver, no bandwidth will be available for other applications.

Enable QoS – Enable Quality of Service. Check this box if you wish to use Quality of Service. Click [Apply] to confi rm.

Adding a QoS rule

• Click [Add].
• Enter a name for the rule in the Rule Name field. This could be the name of the application the rule relates to.
• Under Bandwidth, the first field allows you to select whether the rule will apply to incoming traffic (Download) or outgoing traffic (Upload). If you need to establish rules for both incoming and outgoing traffic, you must set up one rule for each.
• In the second field, enter the amount of bandwidth you wish to reserve. This must be given in kilobits per second (kbps).
• In the third field, indicate whether the bandwidth entered is a guaranteed minimum (Guarantee) or a maximum limit that cannot be exceeded (Max).
• In the Local IP Address field, enter the local IP addresses the rule will apply to. Enter a start address and end address in the fields. For example, 192.168.2.1-192.168.2.255 would represent all the computers on the network 192.168.2.xxx (where “xxx” is a number between 1 and 255)
• In the Local Port Range field, enter the local network ports the rule should apply to. If the application only uses a single port, enter it in this field. Otherwise a range of ports can be specified by using a hyphen. For example: 800-1000, which specifies all ports between 800 and 1000.
• In the Remote IP Address field, enter an IP address on the Internet, from which all traffic will be subject to the rule. Traffic not originating from this address will not be affected. It is not normally necessary to enter a value for this fi eld.
• In the Remote Port Range fi eld, enter one or more ports, from which all traffi c will be subject to the rule. Traffi c not originating from these ports and the address entered under Remote IP Address will not be affected. It is not normally necessary to enter a value for this field.
• Traffic Type – Choose between a range of predefined types of network traffic. If you select a type here, you do not need to enter a value for Local Port Range. The options are:
  • None – No traffi c type is selected. Select this if a value has been entered for Local Port Range.
  • SMTP – Outgoing email.
  • HTTP – World Wide Web.
  • POP3 – Incoming email.
  • FTP – FTP server.
• Protocol – Select the network protocol the rule applies to. You can select either TCP or UDP. Information on the protocols used by an application can be found in the application’s documentation. If an application uses both protocol types, two QoS rules must be set up.
• Click [Save] to add the rule. Click [OK]. Click [Apply].

Moving a QoS rule

If a rule needs to be allocated higher or lower priority, it can be moved up or down the list.

• To select a rule, check the box next to it in the Select column.
• Click [Move Up] to give the rule higher priority or [Move Down] to give it lower priority.
• Click [Apply].

Deleting a QoS rule

• To select a rule, check the box next to it in the Select column.
• Click [Delete Selected].
• Click [OK] in the two boxes that appear.
• Click [Apply].

Deleting all QoS rules

• To select a rule, check the box next to it in the Select column.
• Click [Delete All].
• Click [OK] in the two boxes that appear.
• Click [Apply].

NAT (Network Address Translation) is a technology that allows multiple computers on a local area network to share the same external IP address. The way this works is that the router manages all the network traffic originating from the computers on the network and sorts incoming network traffic so it is redirected to the right computer. However, this may cause a problem for network traffic that is not initiated at the request of a computer on the local area network.

A typical scenario is when a computer on the local area network is set up as a server. In this case, a computer on the Internet would connect to the router’s external IP address. However, this network request does not indicate which computer on the local area network it is addressed to, and the router therefore has no means of knowing where to forward it. This is solved by setting up the router’s NAT function so that it forwards incoming network traffic on certain network ports to a specific IP address on the local area network.

Example: An FTP server is set up on a computer on the network with the IP address 192.168.2.100. FTP uses network port 21 by default. The router’s NAT function is set up to forward all incoming traffic on port 21 to IP address 192.168.2.100.

It may also be necessary to configure NAT for applications such as IP telephony, fi le sharing and online gaming to work properly. NAT can be configured in two modes: Port Forwarding and/or Virtual Server. These are described in the following sections.

Port Forwarding

Port Forwarding means setting up rules specifying the type of network traffi c to be redirected to a particular computer on the local area network.
NB: For Port Forwarding to work as intended, the computer that network traffi c is forwarded to must be confi gured with a static IP address. See section 3.6.3 for information on this.

• Click [General Setup]. Click [NAT]. Click [Port Forwarding].
• Check the box next to Enable Port Forwarding.
• Enter the IP address of the computer on the local area network to redirect to in the
  Private IP field.
• Specify the type of network traffic to redirect under Type. Select TCP, UDP or both (Both).
• The network traffic type depends on the type of application used on the computer that traffic is forwarded to. If necessary, see the application’s documentation for details on this.
• Enter the ports from which network traffic should be forwarded in the Port Range field.
• If you wish, enter a comment in the Comment field.
• Click [Apply].

You can edit the defined rules in the list at the bottom of the screen.
Delete a rule – Check the box next to the rule in the Select column. Click [Delete Selected]. Delete all rules – Click [Delete All].

Virtual Server

Virtual Server works in almost the same way as Port Forwarding. The only difference is that network traffi c arriving at an external network port can be forwarded to another network port on a computer on the local area network. This might be useful if you have a server set up on the local area network that does not use the default port.

Example: An FTP server is set up on a computer on the local area network with the IP address 192.168.2.100. This server does not use default port 21, but instead uses port 3015. Virtual Server can be set up to forward all incoming traffi c on port 21 to IP address 192.168.2.100 on port 3015. This means that users of the FTP server do not have to change the port number used by their FTP application to connect to the server.

NB: For Virtual Server to work as intended, the computer that network traffi c is forwarded to must be confi gured with a static IP address. See section 3.6.3 for information on this.

• Click [General Setup]. Click [NAT]. Click [Virtual Server].
• Check the box next to Enable Virtual Server.
• Enter the IP address of the computer on the local area network to redirect to in the Private IP field.
• Enter the port on the local area network to redirect traffi c to in the Private Port fi eld.
• Specify the type of network traffi c to redirect under Type. Select TCP, UDP or both (Both).
• The network traffic type depends on the type of application used on the computer that traffic is forwarded to. If necessary, see the application’s documentation for details on this.
• Enter the external ports from which network traffic should be forwarded in the Public Port fi eld.
• If you wish, enter a comment in the Comment field.
• Click [Apply].

You can edit the defi ned rules in the list at the bottom of the screen.
Delete a rule – Check the box next to the rule in the [Select] column. Click [Delete Selected]. Delete all rules – Click [Delete All].
