Installing Environmental specifications

Installing

This chapter describes installing your FortiWiFi unit in your server room, environmental specifications and how to mount the FortiWiFi in a rack if applicable.

This chapter contains the following topics:

• Environmental specifications

• Cautions and warnings

• Plugging in the FortiWiFi

• Turning off the FortiWiFi unit

Environmental specifications

• Operating temperature: 32 to 104°F (0 to 40°C) If you install the FortiWiFi unit in a closed or multi-unit rack assembly, the

operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, make sure to install the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature.

• Storage temperature: -13 to 158°F (-25 to 70°C)

• Humidity: 5 to 90% non-condensing

• Air flow - For rack installation, make sure that the amount of air flow required for safe operation of the equipment is not compromised.

• For free-standing installation, make sure that the appliance has at least 1.5 in. (3.75 cm) of clearance on each side to allow for adequate air flow and cooling.

This device complies with part FCC Class A, Part 15, UL/CUL, C Tick, CE and VCCI. Operation is subject to the following two conditions:

• This device may not cause harmful interference, and

• This device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

FortiWiFi-60B FortiOS 3.0 MR6 Install Guide 01-30006-0447-20080131 13

Cautions and warnings Installing

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

The equipment compliance with FCC radiation exposure limit set forth for uncontrolled Environment.

Cautions and warnings

Review the following cautions before installing your FortiWiFi unit.

Grounding

• Ensure the FortiWiFi unit is connected and properly grounded to a lightning and surge protector. WAN or LAN connections that enter the premises from outside the building should be connected to an Ethernet CAT5 (10/100 Mb/s) surge protector.

• Shielded Twisted Pair (STP) Ethernet cables should be used whenever possible rather than Unshielded Twisted Pair (UTP).

• Do not connect or disconnect cables during lightning activity to avoid damage to the FortiWiFi unit or personal injury.

Rack mount instructions

Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.

Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

Mounting

If required to fit into a rack unit, remove the rubber feet from the bottom of the FortiWiFi unit.

Adhere the rubber feet included in the package to the underside of the FortiWiFi unit, near the corners of the device.

FortiWiFi-60B FortiOS 3.0 MR6 Install Guide

14 01-30006-0447-20080131

Installing Setting up a wireless network

Place the FortiWiFi unit on any flat, stable surface. Ensure the unit has at least 1.5 inches (3.75 cm) of clearance on each side to ensure adequate airflow for cooling.

Alternatively, you can use the mounting brackets to mount the FortiWiFi to a wall. To attach the mounting brackets, place the bracket so that the flat portion is away from the FortiWifi, and the bracket is supported by the bracket side bars. Use the four screws supplied to attach the bracket to the FortiWiFi unit. Repeat for the other bracket. See the illustration below for how the bracket is attached.

Figure 2: FortiWiFi with attached mounting bracket

To mount to the wall, measure where the holes in the brackets are on the wall, and inser nails or screws. Hang the FortiWiFi on the nails or screws from the brackets.

Setting up a wireless network

When placing the FortiWiFi access point (AP), your main concern is providing a strong signal to all users. A strong signal ensures a fast connection and the efficient transfer of data. A weaker signal means a greater chance of data transmission errors and the need to re-send information, slowing down data transfer.

Consider the following guidelines when placing the FortiWiFi AP:

• Physical barriers can impede the radio signals. Solid objects such as walls, furniture and people absorb radio waves, weakening the signal. Be aware of the physical barriers in your office space that may reduce a signal. If there is enough physical interference, you may encounter dead spots that receive no signals.

• Ensure the FortiWiFi AP is located in a prominent location within a room for maximum coverage, rather than in a corner.

• Construction materials used in a building can also weaken radio signals. Rooms with walls of concrete or metal can affect the signal strength.

FortiWiFi-60B FortiOS 3.0 MR6 Install Guide 01-30006-0447-20080131 15

Setting up a wireless network Installing

Radio Frequency interface

The 802.11b/g standard uses a frequency range of 2.4 to 2.483 GHz and the

802.11a standard transmit at 5 GHz. Radio frequency (RF) interference occurs when other devices send RF signals during their normal operation that use the same frequency as the FortiWiFi AP. Wireless devices such as cordless phones, microwave ovens and Bluetooth devices can interfere with packet transmissions on a wireless network.

To avoid RF interference:

• Remove these devices from the immediate area where users are working. Something as simple as a Bluetooth enabled mouse may cause transmission interruptions.

• Keep the FortiWiFi AP and wireless devices at least 10 feet away from appliances such as microwave ovens and cordless phones.

• If you must have a cordless phone, select one that does not use the 2.4GHz frequency range for b/g or 5GHZ frequency range for wireless a.

• Consider more FortiWiFi APs to help strengthen the signal. The weaker the signal, the slower the transmission will be as it tries to compete against other wireless devices.

• Set a channel that users and FortiWiFi APs will specifically use can improve signal quality.

Using multiple access points

If you cannot avoid some of these impediments due to the shape of the office or building materials used, you may need to use multiple FortiWiFi APs to help distribute the radio signal around the room. Figure 3 shows how positioning two FortiWiFi APs within a uniquely shaped office space helps to distribute signals around the area.

Figure 3: Using multiple APs to provide a constant strong signal.

Installing Plugging in the FortiWiFi

This sample office has washrooms, a stairwell and an elevator shaft in the center of the building, making it impossible to use a single FortiWiFi AP effectively. The elevator shaft and multiple metal stalls in the washrooms can cause signal degradation. However, placing a FortiWiFi AP in opposite corners of the office provides maximum coverage.

When using multiple APs, each FortiWiFi AP should be set to a different channel to avoid interference in areas where signals from both FortiWiFi units can be received.

Plugging in the FortiWiFi

Use the following steps to connect the power supply to the FortiGate unit.

To power on the FortiGate unit 1 Connect the AC adapter to the power connection at the back of the FortiGate unit. 2 Connect the AC adapter to the power cable. 3 Connect the power cable to a power outlet.

The FortiGate unit starts and the Power and Status LEDs light up. The Status

LEDs flash while the FortiGate unit starts up, and remain lit when the system is

running.

Connecting to the network

Using the supplied Ethernet cable, connect one end of the cable to your router or

modem, whatever the connection is to the Internet. Connect the other end to the

FortiWiFi unit. Connect to either the External, WAN port, or port 1. Connect

additional cable to the Internal port or port 2 and your internal hub or switch.

Turning off the FortiWiFi unit

Always shut down the FortiWiFi operating system properly before turning off the

power switch to avoid potential hardware problems.

To power off the FortiWiFi unit 1 From the web-based manager, go to System > Status. 2 In the Unit Operation display, select Shutdown, or from the CLI enter:

execute shutdown

3 Disconnect the power cables from the power supply.

Configuring NAT vs. Transparent mode

Configuring

This section provides an overview of the operating modes of the FortiWiFi unit,

NAT/Route and Transparent, and how to configure the FortiWiFi unit for each

mode. There are two ways you can configure the FortiWiFi unit, using the

web-based manager or the command line interface (CLI). This section will step

through using both methods. Use whichever you are most comfortable with.

This section includes the following topics:

• NAT vs. Transparent mode

• Connecting to the FortiWiFi unit

• Verify the configuration

• Backing up the configuration

• Additional configuration

NAT vs. Transparent mode

NAT mode

The FortiWiFi unit can run in two different modes, depending on your network

infrastructure and requirements. You have a choice between NAT/Route mode

and Transparent mode. Both include the same robust network security features

such as antispam, antivirus, VPN and firewall policies.

In NAT/Route mode, the FortiWiFi unit is visible to the network. Like a router, all its

interfaces are on different subnets.

In NAT mode, each port is on a different subnet, enabling you to have a single IP

address available to the public Internet. The FortiWiFi unit performs network

address translation before it sends and receives the packet to the destination

network.

In Route mode, there is no address translation.

192.168.1.20

You typically use NAT/Route mode when the FortiWiFi unit is operating as a

gateway between private and public networks. In this configuration, you would

create NAT mode firewall policies to control traffic flowing between the internal,

private network and the external, public network, usually the Internet.

Connecting to the FortiWiFi unit Configuring

Transparent mode

In Transparent mode, the FortiWiFi unit is invisible to the network. Similar to a network bridge, all FortiGate interfaces must be on the same subnet. You only have to configure a management IP address to make configuration changes. The management IP address is also used for antivirus and attack definition updates.

You typically use the FortiWiFi unit in Transparent mode on a private network behind an existing firewall or behind a router. The FortiWiFi unit performs firewall functions, IPSec VPN, virus scanning, IPS web filtering, and Spam filtering.

Connecting to the FortiWiFi unit

To configure, maintain and administer the FortiWiFi unit, you need to connect to it. There are two methods for these tasks:

• using the web-based manger, a GUI interface using a current web browser such as FireFox or Internet Explorer.

• using the command line interface (CLI), a command line interface similar to DOS or UNIX commands using an SSH terminal or Telnet terminal.

Connecting to the web-based manager

To connect to the web-based manager, you require:

• a computer with an Ethernet connection

• Microsoft Internet Explorer version 6.0 or higher or any recent version of the most popular web browser

• an Ethernet cable.

Transparent mode policies controlling traffic between internal and external networks.

10.10.10.3

To connect to the web-based manager

1 Set the IP address of the management computer to the static IP address

192.168.1.2 with a netmask of 255.255.255.0.

2 Using the Ethernet cable, connect the internal interface of the FortiWiFi unit to the

computer Ethernet connection.

3 Start your browser and enter the address https://192.168.1.99. (remember to

include the “s” in https://).

FortiWiFi-60B FortiOS 3.0 MR6 Install Guide

20 01-30006-0447-20080131

Configuring Connecting to the FortiWiFi unit

To support a secure HTTPS authentication method, the FortiWiFi unit ships with a self-signed security certificate, which is offered to remote clients whenever they initiate a HTTPS connection to the FortiWiFi unit. When you connect, the FortiWiFi unit displays two security warnings in a browser.

The first warning prompts you to accept and optionally install the FortiWiFi unit’s self-signed security certificate. If you do not accept the certificate, the FortiWiFi unit refuses the connection. If you accept the certificate, the FortiGate login page appears. The credentials entered are encrypted before they are sent to the FortiWiFi unit. If you choose to accept the certificate permanently, the warning is not displayed again.

Just before the FortiGate login page is displayed, a second warning informs you that the FortiGate certificate distinguished name differs from the original request. This warning occurs because the FortiWiFi unit redirects the connection. This is an informational message. Select OK to continue logging in.

4 Type admin in the Name field and select Login.

Connecting to the CLI

To connect to the FortiGate CLI you require:

• a computer with an available communications port

• a serial cable, either a RJ-45 to DB-9 or null modem cable, whichever was included in your FortiGate package

Configuring NAT mode Configuring

Configuring NAT mode

Configuring NAT mode involves defining interface addresses and default routes, and simple firewall policies. You can use the web-based manager or the CLI to configure the FortiWiFi unit in NAT/Route mode.

Using the web-based manager

After connecting to the web-based manager, you can use the following procedures to complete the basic configuration of the FortiWiFi unit. Ensure you read the section “Connecting to the web-based manager” on page 20 before beginning.

Configure the interfaces

When shipped, the FortiWiFi unit has a default address of 192.168.1.99 and a netmask of 255.255.255.0. for either the Port 1 or Internal interface. You need to configure this and other ports for use on your network.

To configure interfaces 1 Go to System > Network > Interface. 2 Select the edit icon for an interface. 3 Set the Addressing Mode for the interface.

• For Manual addressing, enter the IP address and netmask for the interface.

• For DHCP addressing, select DHCP and complete the following:

Distance Enter the administrative distance, between 1 and 255 for the

• For PPPoE addressing, select PPPoE, and complete the following:

Username Enter the username for the PPPoE server. This may have

assigned you a block of IP addresses, use one of these IP addresses. Alternatively, you can use, or borrow, the IP address of a configured interface on the router. You may need to do this to minimize the number of unique IP addresses within your network.

If you are borrowing an IP address remember the interface must be enabled, or up to function correctly.

4 Select OK. 5 Repeat this procedure for each interface as required.

Note: If you change the IP address of the interface you are connecting to, you must

connect through a web browser again using the new address. Browse to https:// followed by the new IP address of the interface. If the new IP address of the interface is on a different subnet, you may have to change the IP address of your computer to the same subnet.

Configure a DNS server

A DNS server is a service that converts symbolic node names to IP addresses. A domain name server (DNS server) implements the protocol. In simple terms, it acts as a phone book for the Internet. A DNS server matches domain names with the computer IP address. This enables you to use readable locations, such as fortinet.com when browsing the Internet.

DNS server IP addresses are typically provided by your internet service provider.

To configure DNS server settings 1 Go to System > Network > Options. 2 Enter the IP address of the primary DNS server. 3 Enter the IP address of the secondary DNS server. 4 Select Apply.

Adding a default route and gateway

A route provides the FortiWiFi unit with the information it needs to forward a

packet to a particular destination. A static route causes packets to be forwarded to

a destination other than the default gateway. You define static routes manually.

Static routes control traffic exiting the FortiWiFi unit-you can specify through which

interface the packet will leave and to which device the packet should be routed.

In the factory default configuration, entry number 1 in the Static Route list is

associated with a destination address of 0.0.0.0/0.0.0.0, which means any/all

destinations. This route is called the "static default route". If no other routes are

present in the routing table and a packet needs to be forwarded beyond the

FortiWiFi unit, the factory configured static default route causes the FortiWiFi unit

to forward the packet to the default gateway.

Configuring NAT mode Configuring

For an initial configuration, you must edit the factory configured static default route to specify a different default gateway for the FortiWiFi unit. This will enable the flow of data through the FortiWiFi unit.

For details on adding additional static routes, see the FortiGate Administration Guide.

To modify the default gateway 1 Go to Router > Static. 2 Select Edit for the default route 3 In the Gateway field, type the IP address of the next-hop router where outbound

traffic is directed. 4 If the FortiWiFi unit reaches the next-hop router through a different interface

(compared to the interface that is currently selected in the Device field), select the

name of the interface from the Device field.

5 Select OK.

Adding firewall policies

Firewall policies enable traffic to flow through the FortiWiFi interfaces. Firewall

policies define how the FortiWiFi unit processes the packets in a communication

session. You can configure the firewall policies to allow only specific traffic, users

and specific times when traffic is allowed.

For the initial installation, a single firewall policy that enables all traffic through will

enable you to verify your configuration is working. On lower-end units such a

default firewall policy is already in place. For the higher end FortiWiFi units, you

will need to add a firewall policy.

The following steps add two policies that allows all traffic through the FortiWiFi

unit, to enable you to continue testing the configuration on the network.

To add an outgoing traffic firewall policy 1 Go to Firewall > Policy. 2 Select Create New. 3 Set the following and select OK.

Source Interface Select the port connected to the network.

Source Address All

Destination Interface Select the port connected to the Internet.

Firewall policy configuration is the same in NAT/Route mode and Transparent mode.

Note that these policies allow all traffic through. No protection profiles have been applied. Ensure you create additional firewall policies to accommodate your network requirements.

For details, see the FortiGate Administration Guide.

Using the CLI

After connecting to the CLI, you can use the following procedures to complete the basic configuration of the FortiWiFi unit. Ensure you read the section “Connecting

to the CLI” on page 21 before beginning.
