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 - web-based manager
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.
4 Select Apply.
