    It is unclear what you are asking. The FortiGate supports setting a static IP on any interface.
    If you are behind an ISP modem and that is giving you a private address, you would probably need to set it to bridged mode and that will give you the correct WAN IP directly on the FortiGate.
    Whether or not that will be static depends on your ISP.

    Never trust a computer you can't throw out a window.

      Sounds like...you have multiple static IPs from your ISP and currently terminated at the modem/router from the ISP. And, you want to utilize one of them at your 40F behind the modem. Is that what you intended to say?
      If so we need to know the subnet mask you got, or multiple public subnets.

        The wan interface pulls one IP via the modem likely in a /30 subnet, which probably a public IP from the ISP. If you have additional public subnet like a /29 from the ISP, you can configure it on the LAN side. Is that what you have?

          You solved my problem also, thank you so much for your help.

          Yes, you can configure a static IP on your FortiGate 40F's WAN interface if your modem provides a public or private IP for manual assignment. Ensure the IP you set is within the modem's network range, with the correct subnet mask, gateway, and DNS. If your ISP provides a static public IP, use those details instead. My cousin was stressed about her book report deadline, so I helped her look for resources. That’s when we discovered this https://academized.com/buy-book-report service, and it was exactly what she needed. The report was detailed, insightful, and well-written. Her teacher was very impressed, and she couldn’t have been happier with the outcome. It was wonderful to see her confidence grow, and I’m glad we found such a reliable option.
