Web-based Manager
1. Connect the internal interface to a management computer Ethernet interface. Use
straight-through Ethernet cables to connect the devices through a hub or switch.
2.
Configure the management computer to be on the same subnet as the internal inter
-
face of the unit. To do this, change the IP address of the management computer to
192.168.1.2 and the netmask to 255.255.255.0.
3.
To access the web-based manager, start Internet Explorer and browse to
https://192.168.1.99 (remember to include the “s” in https://).
4.
Type admin in the Name field and select Login.
NAT/Route mode

Command Line Interface
1.
Use the RJ-45 to DB9 serial cable to connect the unit’s Console port to the manage
-
ment computer serial port.
2. Start a terminal emulation program (HyperTerminal) on the management computer. Use
these settings:
•
Baud Rate (bps) 9600, Data bits 8, Parity None, Stop bits 1, and Flow Control None.
3.
At the Login prompt, type admin and press Enter twice (no password required).
NAT/Route mode
1.
Configure the internal interface.
config system interface
edit internal
set ip <intf_ip>/<netmask_ip>
end
2.
Repeat to configure each interface, for example, to configure the WAN interface.
config system interface
edit wan
...
3.
Configure the primary and secondary DNS server IP addresses.
config system dns
set primary <dns-server_ip>
set secondary <dns-server_ip>
end
4.
Configure the default gateway.
config router static
edit 1
set gateway <gateway_ip>
end
Transparent Mode
1.
Change from NAT/Route mode to Transparent mode and configure the Management IP
address.
config system settings
set opmode transparent
set manageip <mng_ip>/<netmask>
set gateway <gateway_ip>
end
2.
Configure the DNS server IP address.
config system dns
set primary <dns-server_ip>
set secondary <dns-server_ip>
end
Collecting Information
Configuring
NAT/Route Mode
In NAT/Route mode, the unit is visible to the network that it is connected to. All of its inter
-
faces are on different subnets. Each interface connected to a network must be configured
with an IP address that is valid for that network.
You would typically use NAT/Route mode when the unit is deployed as a gateway between
private and public networks. In its default NAT/Route mode configuration, the unit functions
as a firewall. Firewall policies control communications through the unit.
In NAT/Route mode, firewall policies can operate in NAT mode or in Route mode. In NAT
mode, the unit performs network address translation before IP packets are sent to the
destination network. In Route mode, no translation takes place.
Transparent Mode
In Transparent mode, the unit is invisible to the network. All of its interfaces are on the same
subnet. You only have to configure a management IP address so that you can make configu
-
ration changes.
You would typically use the unit in Transparent mode on a private network behind an existing
firewall or behind a router. In its default Transparent mode configuration, the unit functions
as a firewall. You can connect up to three network segments to the unit to control traffic
between these network segments.
Refer to the Tools and Documentation CD-ROM for information on how to control traffic, and how to configure wireless connections, antivirus protection, FortiGuard, Web content filtering, Spam filtering, intrusion
prevention (IPS), and virtual private networking (VPN).
