DNS Fortigate

[luca1994]

Hello team,

I would like to know what is the difference in having the firewall use Fortinet DNS or local internal network DNS, for example Windows Server DNS.

Thanks for the support

Hi Luca

Using Fortinet DNS or other public DNS will allow your FortiGate to resolve public domains only.

Using a private DNS server will allow your FortiGate resolve internal hostnames, and external as well (if your DNS server forwards queries to external).

This can be useful in some cases, e.g.: You can have a firewall policy allowing your hosts using their hostnames instead of IP addresses.
