[Fortinet] Fortigate CLI Commands - DNS 설정

DNS CLI

 

DNS settings can be configured with the following CLI command:

config system dns
    set primary <ip_address>
    set secondary <ip_address>
    set dns-over-tls {enable | disable | enforce}
    set ssl-certificate <string>
    set domain <domains>
    set ip6-primary <ip6_address>
    set ip6-secondary <ip6_address>
    set timeout <integer>
    set retry <integer>
    set dns-cache-limit <integer>
    set dns-cache-ttl <integer>
    set cache-notfound-responses {enable | disable}
    set source-ip <class_ip>
end Copy

 

For a FortiGate with multiple logical CPUs, you can set the DNS process number from 1 to the number of logical CPUs.

 

The default DNS process number is 1.

config system global
    set dnsproxy-worker-count <integer>
end

 

dns-over-tls

 

DNS over TLS (DoT) is a security protocol for encrypting and wrapping DNS queries and answers via the Transport Layer Security (TLS) protocol. It can be enabled, disabled, or enforced:

• disable: Disable DNS over TLS (default).
• enable: Use TLS for DNS queries if TLS is available.
• enforce: Use only TLS for DNS queries. Does not fall back to unencrypted DNS queries if TLS is unavailable.

For more information, see DNS over TLS.

cache-notfound-responses

 

When enabled, any DNS requests that are returned with NOT FOUND can be stored in the cache. The DNS server is not asked to resolve the host name for NOT FOUND entries. By default, this option is disabled.

 

dns-cache-limit

Set the number of DNS entries that are stored in the cache (0 to 4294967295, default = 5000). Entries that remain in the cache provide a quicker response to requests than going out to the Internet to get the same information.

 

dns-cache-ttl

The duration that the DNS cache retains information, in seconds (60 to 86400 (1 day), default = 1800).
