Use this command to configure the IP addresses of the primary and secondary DNS servers
that the FortiVoice unit will query to resolve domain names into IP addresses.
Syntax
config system dns
set cache {enable | disable}
set primary <dns_ipv4>
set private_ip_query {enable | disable}
set secondary <dns_ipv4>
end
Variable Description Default
cache {enable | disable} Enable to cache DNS query results, improving
performance.
Disable the DNS cache to free memory if you are low on
memory.
enable
primary <dns_ipv4> Enter the IP address of the primary DNS server. 0.0.0.0
private_ip_query
{enable | disable}
Enable to perform reverse DNS lookups on private
network IP addresses, as defined in RFC 1918. The DNS
server must have PTR records for your private network’s
IP addresses. Failure to contain records for those IP
addresses may increase DNS query time and cause
query results to be ‘Host not found’.
disable
secondary <dns_ipv4> Enter the IP address of the secondary DNS serve. 0.0.0.0
