Fortinet Tool

None that I'm aware of.

What we've done in the past to quick deploy fortios is to defined a base-cfg and install this on the usb.stick and you can boot the unit after making the changes and let teh cfg load.

We just modify the name, wan/lan address and install that config for the unit that's being turn up. Great if you use the same exact model of fgt.

We had a script that took our basic cfg and prompts for the changes and modify the values ( wan-ipv4.addr lan-ipv4.addr and default gateway , etc.....)
