Hello All,

I am running FG200D (5.2.10)

 

we are facing issue , we are not able to access some website through fortigate unit i got the following message in web browser "DNS_PROBE_FINISHED_NXDOMAIN"

I had exempted this sites in the "web profile" and ssl inspection, but the problem still persist.

 

Note : when assign  Google DNS(8.8.8.8) to the "NIC" I can  access site.  

 

please advise me accordingly.

 

Thanks

    Hello CAD,

     

    Are you using an internal DNS server? Can you send me your configuration file and a packet capture? You can PM me the files. Please let me know which policy ID are you using too. Thanks.

    Hi @Marwan,

     

    You can use a different DNS server. Preferably 8.8.8.8.
