Internal DNS
When FortiWAN receives a request from a client, the request will be redirected to the cache server. In this case, the
data requested already exists on the cache server. Therefore it will return the data requested to the client without
passing the actual request to the internet.
Internal DNS
Internal DNS is the DNS server built in FortiWAN used to manage your domain for internal users. Internal DNS resolve
domain name for DNS requests coming from LAN or DMZ subnets. FortiWAN's Internal DNS is recursive DNS, which
allows users to resolve other people's domains. The DNS servers set in
System > Network Setting > DNS Server
will be asked by Internal DNS while it recursively resolve an unknown domain (See "
"). In
case that all the set DNS servers are not available or the DNS server is not configured, Internal DNS will ask the root
domain name server for resolving the domain. Allocate the Internal DNS to users in LAN and DMZ subnets by
manually set the DNS server on their computers to the gateways, which are LAN ports or DMZ ports. It is unable to
automatically allocate FortiWAN's internal DNS to users by FortiWAN's DHCP. An user in LAN or DMZ subnet need to
manually configure the DNS server on its computer to the gateway it connects to for using FortiWAN's Internal DNS.
