Hello, according to the user handbook
https://download.zyxel.com/USG_FLEX_50H/user_guide/USG%20FLEX%2050H-UG.pdf
the Zyxel Flex 50H supports a maximum of 32 custom IPS signatures:

How can I add these custom IPS signatures? I couldn't find a way in the user handbook or in the CLI guide.

    Hi @best_heygman,

    Thank you for your patience.

    After checking, the Zyxel USG Flex H series firewall does not support custom IPS signatures.

    The mention of "up to 32 custom IPS signatures" in the user guide was an error. We'll correct and remove this misinformation promptly.

    We regret any inconvenience and confusion this caused!
