Hi folks,
just installed a FGT in transparent mode in the "BACK" of another Fortigate. (Because I try to offload some tasks, to this FGT).
This is working for surfing the internet, but not when I try to resolve internal domainnames.
Every internal lookup resolves to IP: 208.91.112.55
In the FGT I set the primary and secondary DNS Server to my internal DCs.
The networkconfig is:
LAN <-> (lanport) FGT Transparent (wanport) <-> (lanport) FGT NAT (wanport) <-> Internet
Any help will be very nice.
Thanks!

seems it is connected to some security filters.
EDIT: Finally it was the DNS -Filter. After deactivating it resolving of internal IPs is working again.
Thanks!
