The "best" firmware for a FortiGate 100D is FortiOS v6.0.15 (or v6.0.14 if 6.0.15 is unavailable). This is the final stable build released for the platform. Do not attempt to install v6.2 or later; the 100D lacks the hardware specifications (specifically NAND flash and RAM) to run these versions, leading to boot loops or crashes.
Do not attempt to download the latest FortiOS (v7.2, v7.4, or v7.6). The FortiGate 100D reached its End of Life (EOL) and End of Support (EOS) dates.
| Version | Status | Recommendation | | :--- | :--- | :--- | | v6.0.15 | Final Release (Sept 2022) | BEST – Last security patches. Most stable for EOL hardware. | | v6.0.14 | Prior stable release | Acceptable if 6.0.15 is inaccessible. | | v6.0.10 | Older stable release | Only for legacy compatibility. | | v6.2.x | Unsupported | Do not use – Causes filesystem corruption and boot loops. |
Why v6.0.15 is best: It contains all known security fixes up to the EOL date. It fixes SSL VPN vulnerabilities (like CVE-2022-40684) that earlier 6.0.x versions are missing.
The Kruti Dev 055 font is widely used for typing in Devnagari letter on various computer platforms, especially in India. It leverages the Alt key shortcut combinations to input specific Devnagari letter characters that are not directly available on the standard keyboard. For instance, pressing Alt + 0161 inputs the character "फ़," while Alt + 0162 generates "ख." Similarly, Alt + 0163 produces "ग," Alt + 0164 types "घ," and Alt + 0165 results in "ङ." These shortcuts are particularly useful for typists and professionals who need to create documents in Devnagari letter efficiently. By memorizing these Alt codes, users can enhance their typing speed and accuracy, ensuring that they can produce the necessary characters quickly without having to search for them. This system of using Alt key combinations simplifies the process of typing in Devnagari, making Kruti Dev 055 a popular choice among Devnagari language typists.
