If you are still in doubt about NAT mode, check out this post we created especially for you.
A valuable tip from Fortinet is to use Virtual Domains (VDOMs) to group related interfaces or VLAN sub-interfaces together.
The use of VDOMs and transparent mode are especially useful when the network is complex and does not allow changes to the IP addressing scheme.

We will discuss everything from proper configuration, to implementing security policies, to recommendations for system maintenance. Our goal is to provide useful insights that enable robust network protection while getting the most out of Fortinet Firewall. Whether you are new to IT security or a seasoned professional, the following tips will be a valuable resource to ensure your security practices are aligned with industry best practices.
Managing Resources Efficiently
Disable all unnecessary management features. If SSH or SNMP are not necessary for you, it is best to disable them to avoid possible infiltrators.
Put the most used firewall rules at the top of the interface list and log only the necessary traffic. Recording logs can slow performance, especially if it is on an internal hard drive. Fortunately, Fortinet offers alternatives in the cloud or with appliances.
Enabling Only Necessary Inspections
In your Fortigate Firewall, enable only the necessary application inspections. Keep alert systems to a minimum. If you send logs to a syslog server, you probably don't need SNMP or email alerts, which will avoid redundant processing.
Establish scheduled FortiGuard updates at a reasonable frequency to keep your network security always up to date.
