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.

Router

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.

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 FortiGate 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://).

FortiGate-310B FortiOS 3.0 MR6 Install Guide

18 01-30006-0472-20080815

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.
