Fortigate Tutorial 1 – Firewall Default Settings
Here are the default settings for almost all of the Fortigate Firewall:
Internal: 192.168.1.99
WAN1: 192.168.100.99
WAN2: 192.168.101.99
DHCP is enabled by default on the internal interface with the following scope: 192.168.1.110 till 192.168.1.210
Default username: Admin
Default password: <none>
Now you can connect to the firewall with SSH on port 22 and go from there.
