Configuring Transparent mode
Configuring Transparent mode involves switching to Transparent mode,

procedures to complete the basic configuration of the FortiGate unit. Ensure you

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
1 Go to System > Network > Options.
2 Enter the IP address of the primary DNS server.
3 Enter 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.
