Fortigate DNS Server reverse lookup

Hi,
 
my Foritgate is acting as a DNS server with static entrys. However a revrese lookup (ip to name) on a client which have fortigate as a DNS server configured gives no result.
 
Is there an additional setting which have to be configured for DNS reverse lookup?
 
Kind Regards,
 Juergen

    In short (as I am on holidays and not at my desk):
    1- You need to create an additional zone, aptly named like a reverse zone.
    2- Populate it with PTR records instead of A records.
     
    Then the FGT will do reverse lookups. It is clumsy, and PTR records are not created automatically, but it works.

    did you configure PTR records for every A record you want the reverse lookup to work for? That's required to get reverse lookups working as far as I know.
