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.

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:

IP Prefix 0.0.0.0 (IP address)

0.0.0.0(Netmask)

Next Hop 192.168.1.2

Static Route example:

IP Prefix 172.100.100.0 (IP address) 255.255.255.0 (Netmask)

Next Hop 192.168.1.2
