FortiGate Securing Remote Administration

KB ID 0001734 Problem When considering Securing FortiGate  remote administration, I’ve written about changing the https management port to something other than TCP 443 before, I suppose that’s security by obfuscation (though even a script kiddy with one hours experience, will be able to spot an html responses).  Typically with other vendors you limit remote administration access, to specific IP addresses (or ranges). So...

FortiGate High Availability (Active / Passive)

KB ID 0001730 So my aim was to setup FortiGate High Availability failover in Active / Passive mode.

FortiGate: SSL Inspection (HTTPS Inspection)

KB ID 0001729 Problem Do you inspect the traffic on your network? You have a firewall? Maybe an IDS appliance? That’s good news, do you inspect HTTPS traffic? In most cases the answer is no. Because either you do not have the capability, or enabling SSL Inspection will degrade the firewall’s performance so much that you accept the risk. At time of writing (Early 2021) it’s estimated that 85% of all web traffic is now...

FortiGate: Change the HTTPS Fortigate Management Port

KB ID 0001723 Problem Like all firewalls that have ‘web management’ the default ports are 80 and 443 for insecure and secure management.

So you will need to change the FortiGate Management Port. You can set SSL-VPN to use a different port of course,...
