Hello All,
I want to show a customer the advantages of FortiManager. I installed FortiManager VM and a Fortigate VM using VM Workstation. When I try and add the Fortitgate device to the FortiManager I get "Probe Failed" message.
Both FortiManager and Fortigate are running 5.6 and are in there Trial license period. I have network connectivity to the Fortigate as I can ping it from FortiManager. I have Centralised Management on the Fortigate set to FortiManager:
When I check in the logs I can see a successful connection using TCP/541 from the FortiManager to the Fortigate. The only blocked traffic I see is on TCP/542 from the FortiManager to the Fortigate. 
TCP/542 is not listed in the Local In Policy. Checking the Fortinet Documentation about TCP/542, this port seems to be related to IPv6.
If someone can offer some assistance as to why adding the device is failing. It would be appreciated.
