All you need to do is set your network computers to obtain an IP address automatically and to obtain DNS server IP addresses automatically (using DHCP), access the web-based manager, and configure the required settings for the FortiGate external interface. You can also configure FortiGate DNS servers and add a FortiGate default route if needed.The FortiGate internal interface acts as a DHCP server for the internal network, automatically assigning IP addresses to computers (up to 100 computers) in the range of 192.168.1.110 –192.168.1.210.Figure 6: Quick configuration using default settingsThe FortiGate DHCP server also assigns the DNS server IP address 192.168.1.99 to each computer on the internal network. As a result, the FortiGate unit internal interface acts as a DNS server for the internal network. Using DNS forwarding, the FortiGate unit forwards DNS requests received from the internal network to the DNS server IP addresses added to the FortiGate unit configuration and returns lookup results to the internal network.For more information about default DHCP server settings see “Factory default DHCP server configuration” on page 28.50AFortiGate-50ARouterInternetObtain IP address and DNS server IP address automaticallyInternal interface 192.168.1.99DHCP server and DNS server for the internal network External interface Configuring Manual IP, DHCP, or PPPoE addressing

The default configuration enables you to connect to and use the FortiGate web-based manager to configure the FortiGate unit onto the network. To configure the FortiGate unit, you add an administrator password, change network interface IP addresses, add DNS server IP addresses, and, if required, configure basic routing.If you plan to operate the FortiGate unit in Transparent mode, you can switch to Transparent mode from the factory default configuration and then configure the FortiGate unit onto the network.Once you complete the network configuration, you can perform additional configuration tasks such as setting system time, configuring virus and attack definition updates, and registering the FortiGate unit.The factory default firewall configuration includes a single network address translation (NAT) policy that allows users on your internal network to connect to the external network, and stops users on the external network from connecting to the internal network. You can add more firewall policies to provide more control of the network traffic passing through the FortiGate unit.You can use the factory default protection profiles to apply different levels of antivirus protection, web content filtering, spam filtering, and IPS to the network traffic that is controlled by firewall policies.This section includes the following topics:•Factory default DHCP server configuration•Factory default NAT/Route mode network configuration•Factory default Transparent mode network configuration•Factory default firewall configuration•Factory default protection profiles•Restoring the default settings

You can use protection profiles to:• configure antivirus protection for HTTP, FTP, IMAP, POP3, and SMTP firewall policies• configure Web filtering for HTTP firewall policies• configure Web category filtering for HTTP firewall policies• configure spam filtering for IMAP, POP3, and SMTP firewall policies• enable the Intrusion Protection System (IPS) for all services• enable content logging for HTTP, FTP, IMAP, POP3, and SMTP firewall policiesBy using protection profiles, you can build protection configurations that can be applied to different types of firewall policies. This allows you to customize types and levels of protection for different firewall policies.For example, while traffic between internal and external addresses might need strict protection, traffic between trusted internal addresses might need moderate protection. You can configure firewall policies for different traffic services to use the same or different protection profiles.You can add Protection profiles to NAT/Route mode and Transparent mode firewall policies. The FortiGate unit includes four protection profiles.Configuration setting Name DescriptionFirewall policy Internal -> External Source: All Destination: AllFirewall address All Firewall address matches the source or destination address of any packet.Pre-defined service More than 50 predefined servicesSelect from any of the 50 pre-defined services to control traffic through the FortiGate unit that uses that service.Recurring schedule Always The recurring schedule is valid at any time.Protection Profiles Strict, Scan, Web, UnfilteredControl how the FortiGate unit applies virus scanning, web content filtering, spam filtering, and IPS.Strict To apply maximum protection to HTTP, FTP, IMAP, POP3, and SMTP traffic. You may not use the strict protection profile under normal circumstances but it is available if you have problems with viruses and require maximum screening. Scan To apply antivirus scanning and file quarantining to HTTP, FTP, IMAP, POP3, and SMTP content traffic.Web To apply antivirus scanning and web content blocking to HTTP content traffic. You can add this protection profile to firewall policies that control HTTP traffic.Unfiltered To apply no scanning, blocking or IPS. Use if you do not want to apply content protection to content traffic. You can add this protection profile to firewall policies for connections between highly trusted or highly secure networks where content does not need to be protected.

Before beginning to configure the FortiGate unit, you need to plan how to integrate the unit into your network. Your configuration plan depends on the operating mode you select: NAT/Route mode or Transparent mode.This section includes the following topics:•Planning the FortiGate configuration•Preventing the public interface from responding to ping requests•NAT/Route mode installation•Transparent mode installation•Next stepsPlanning the FortiGate configurationBefore you configure the FortiGate unit, you need to plan how to integrate the unit into the network. Among other things, you must decide whether you want the unit to be visible to the network, which firewall functions you want it to provide, and how you want it to control the traffic flowing between its interfaces.Your configuration plan depends on the operating mode you select. You can also configure the FortiGate unit and the network it protects using the default settings.NAT/Route modeIn NAT/Route mode, the FortiGate unit is visible to the network. Like a router, all its interfaces are on different subnets. The following interfaces are available in NAT/Route mode: Modem is the interface for connecting an external modem to the FortiGate-50A. See “Configuring the modem for the FortiGate-50A” on page 53.You can add firewall policies to control whether communications through the FortiGate unit operating in NAT or Route mode. Firewall policies control the flow of traffic based on the source address, destination address, and service of each packet. In NAT mode, the FortiGate unit performs network address translation before it sends the packet to the destination network. In Route mode, there is no address translation.Table 11: NAT/Route mode network segmentsFortiGate Unit Internal Interface External InterfaceOtherFortiGate-50A Internal External ModemFortiGate-50B Internal WAN1 WAN2FortiWiFi-50B Internal WAN1 WAN2FortiGate-100A Internal External DMZ

In this configuration, you create NAT mode firewall policies to control traffic flowing between the internal, private network and the external, public network (usually the Internet).Figure 7: Example NAT/Route mode network configuration for a FortiGate-50A..NAT/Route mode with multiple external network connectionsIn NAT/Route mode, you can configure the FortiGate unit with multiple redundant connections to the external network (usually the Internet). For example, you could create the following configuration:• External or WAN1 is the default interface to the external network (usually the Internet)• Modem is the redundant interface to the external network for the FortiGate-50A• WAN2 is the redundant interface to the external network on the FortiGate-50B and FortiWiFi-50B.• DMZ is the redundant interface to the external network on the FortiGate-100• Internal is the interface to the internal networkYou must configure routing to support redundant Internet connections. Routing can automatically redirect connections from an interface if its connection to the external network fails.Otherwise, security policy configuration is similar to a NAT/Route mode configuration with a single Internet connection. You would create NAT mode firewall policies to control traffic flowing between the internal, private network and the external, public network (usually the Internet).Figure 8: NAT/Route multiple internet connection configuration for a FortiGate-50A.Internal networkFortiGate-50AInternetRouterExternal204.23.1.5Internal192.168.1.99NAT mode policies controlling traffic between internal and external networks. 192.168.1.3FortiGate-50AInternetInternal networkExternal204.23.1.5 Internal192.168.1.1NAT mode policies controlling traffic between internal and external networks.

Similar to a network bridge, all FortiGate interfaces must be on the same subnet. You only have to configure a management IP address so that you can 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 content filtering, and Spam filtering.Figure 9: Example Transparent mode network configuration for a FortiGate-100Preventing the public interface from responding to ping requestsThe factory default configuration of your FortiGate unit allows the default public interface to respond to ping requests. The default public interface is also called the default external interface, and is the interface of the FortiGate unit that is usually connected to the Internet. For the most secure operation, you should change the configuration of the external interface so that it does not respond to ping requests. Not responding to ping requests makes it more difficult for a potential attacker to detect your FortiGate unit from the Internet. A FortiGate unit responds to ping requests if ping administrative access is enabled for that interface. You can use the following procedures to disable ping access for the external interface of a FortiGate unit. You can use the same procedure for any FortiGate interface. You can also use the same procedure in NAT/Route or Transparent mode. Internal networkInternalInternetRouter FortiGate-100ExternalDMZInternalDMZ network Web ServerMail Server
