Configuring NAT vs. Transparent mode

Configuring

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

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

mode. There are two ways you can configure the FortiGate 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 FortiGate unit

• Verify the configuration

• Backing up the configuration

• Additional configuration

NAT vs. Transparent mode

NAT mode

The FortiGate 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 FortiGate 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 FortiGate 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 FortiGate 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 FortiGate unit Configuring

Transparent mode

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

Connecting to the FortiGate unit

To configure, maintain and administer the FortiGate 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.

FortiGate-60B FortiOS 3.0 MR6 Install Guide

16 01-30006-0446-20080910

Configuring Connecting to the FortiGate unit

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

The first warning prompts you to accept and optionally install the FortiGate unit’s self-signed security certificate. If you do not accept the certificate, the FortiGate 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 FortiGate 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 FortiGate 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

• terminal emulation software such as HyperTerminal for Microsoft Windows

Note: The following procedure uses Microsoft Windows HypterTerminal software. You can apply these steps to any terminal emulation program.

To connect to the CLI

1 Connect the serial cable to the communications port of your computer and to the

FortiGate console port.

2 Start HyperTerminal, enter a name for the connection and select OK. 3 Configure HyperTerminal to connect directly to the communications port on your

computer and select OK.

4 Select the following port settings and select OK:

Bits per second 9600 Data bits 8 Parity None Stop bits 1 Flow control None

5 Press Enter to connect to the FortiGate CLI. 6 When the login prompt appears, type admin and press Enter twice.

Type ? to list available commands. For information about how to use the CLI, see the FortiGate CLI Reference.

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 FortiGate 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 FortiGate unit. Ensure you read the section “Connecting to the web-based manager” on page 16 before beginning.

Configure the interfaces

When shipped, the FortiGate 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

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 FortiGate 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 FortiGate 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

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

to forward the packet to the default gateway.

FortiGate-60B FortiOS 3.0 MR6 Install Guide 01-30006-0446-20080910 19

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 FortiGate unit. This will enable the flow of data through the FortiGate 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 FortiGate 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 FortiGate interfaces. Firewall

policies define how the FortiGate 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 FortiGate units, you

will need to add a firewall policy.

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

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.
