Configuring Transparent mode

Configuring Transparent mode involves switching to Transparent mode, configuring the management IP address, default routes, and simple firewall policies. You can use the web-based manager or the CLI to configure the FortiGate unit in Transparent mode.

Using the web-based manager

After connecting to the web-based manager, you can use the following procedures to complete the basic configuration of the FortiGate unit. Ensure you read the section “Connecting to the web-based manager” on page 16 before beginning.

Switching to Transparent mode

The FortiGate unit comes preset to NAT mode. You need to switch to Transparent mode.

To switch to Transparent mode

1Go to System > Status.

2Select Change beside the Operation Mode.

3Select Transparent.

4Enter the Management IP/Netmask address and the Default Gateway address.

The default gateway IP address is required to tell the FortiGate unit where to send network traffic to other networks.

5Select Apply.

Configure a DNS server

A DNS server is a service that converts symbolic node names to IP addresses. A domain name server (DNS server) implements the protocol. In simple terms, it acts as a phone book for the Internet. A DNS server matches domain names with the computer IP address. This enables you to use readable locations, such as fortinet.com when browsing the Internet.

DNS server IP addresses are typically provided by your internet service provider.

To configure DNS server settings

1Go to System > Network > Options.

2Enter the IP address of the primary DNS server.

3Enter the IP address of the secondary DNS server. Select Apply.

Adding firewall policies

Firewall policies enable traffic to flow through the FortiGate interfaces. Firewall policies define the FortiGate unit process the packets in a communication session. You can configure the firewall policies to allow only specific traffic, users and specific times when traffic is allowed.
