FortiGate Upgrade DNS Issues

FortiGate Upgrade DNS Issues

Some lessons learned while doing a Trade-up of several FortiGates for satellite locations. After using the Forticonverter service the FortiGates (FortiOS 6.0.8 to 7.2.1) would not connect to FortiCloud and I kept getting errors about not connected to FortiGuard. All traffic stopped passing through the firewalls as well. Tried everything under the sun and everything that Fortinet Support told me to do. Nothing worked. It ended up being such a simple fix that I had to send it to Fortinet. Note to self: DON’T FORGET TO CHECK THIS

This is a convenient way to hide information in pictures. Not meant to be a rebellious way to do anything. Just a way for me to hide certain information that could easily be misplaced. Think like a very important password or number considering that password saving utilies often get hacked.
