Fortinet FortiGate 100 Installation & Configuration Guide

Default routes and static routes Transparent mode installation
The FortiGate unit uses HTTPS on port 8890 to check for updates. The FortiGate
external interface must have a path to the FortiResponse Distribution Network (FDN)
using port 8890.
To configure automatic virus and attack updates, see “Updating antivirus and attack
definitions” on page 91.
Transparent mode configuration examples
A FortiGate unit operating in Transparent mode still requires a basic configuration to
operate as a node on the IP network. As a minimum, the FortiGate unit must be
configured with an IP address and subnet mask. These are used for management
access and to allow the unit to receive antivirus and definitions updates. Also, the unit
must have sufficient route information to reach:
• the management computer,
• The FortiResponse Distribution Network (FDN),
• a DNS server.
A route is required whenever the FortiGate unit connects to a router to reach a
destination. If all of the destinations are located on the external network, you may be
required to enter only a single default route. If, however, the network topology is more
complex, you may be required to enter one or more static routes in addition to the
default route.
This section describes:
• Default routes and static routes
• Example default route to an external network
• Example static route to an external destination
• Example static route to an internal destination
Default routes and static routes
To create a route to a destination, you need to define an IP prefix which consists of an
IP network address and a corresponding netmask value. A default route matches any
prefix and forwards traffic to the next hop router (otherwise known as the default
gateway). A static route matches a more specific prefix and forwards traffic to the next
hop router.
Default route example:
Static Route example:
IP Prefix 0.0.0.0 (IP address)
0.0.0.0 (Netmask)
Next Hop 192.168.1.2
IP Prefix 172.100.100.0 (IP address)
255.255.255.0 (Netmask)
Next Hop 192.168.1.2
