FortiGate Port Forwarding

KB ID 0001742 Problem I was back on the tools again today setting up FortiGate Port Forwarding! This was for one of our partners that I have to do some remote work for, so I temporarily needed to get onto their servers. Normally I’d just SSL VPN in, (but that’s what I’m setting up!) So to get onto their servers I had to setup a port forward for RDP. WARNING: Port forwarding RDP from ALL / Any is a BAD IDEA...

FortiGate High Availability (Active / Passive)

KB ID 0001730 So my aim was to setup FortiGate High Availability failover in Active / Passive mode. I’m setting this up in EVE-NG and here’s what my lab looks like; Note: Im using TWO connections for Heartbeat/Failover, you can simply use one if you prefer. FortiGate High Availability (Pre-Requisites) Obviously the firewalls need to be the same! For physical firewalls that’s straightforward, but be careful if you are...

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.
