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.
Verify these on a Fortigate cluster. Commands for HA troubleshooting and things to watch for when upgrading a cluster.
Wireguard VPN quick and easy deployment using docker-compose. Copy this into a file and save it as docker-compose.yml.
Configuration steps for creating automation-stitches via command-line. Create the action first, then the trigger and then stitch it together.
Links to sites I like or that have very specific tutorials. Cisco, Cloud, Coffee, VoIP etc.
Bunch of Fortigate routing commands to help in troubleshooting. Similar to Cisco IOS but not really ;-)
Site-to-Site VPN Tunnel using crypto IPsec IKEV2. Very important to not lose track of names
Secure tunnel over SSH. VNC is a good example of an insecure connection.
