It is possible to create certain domain matches with leading dot '.' in tmsh, but not in the GUI.


You are unable to use the GUI to create custom bot-defense signatures.


Advanced WAF bot signature configuration with domain with a leading . character.


Use tmsh to add custom bot-defense signatures as follows: tmsh create security bot-defense signature ockerdocker category Crawler domains add {.ockerdocker} rule "headercontent:\"Google_Analytics_Snippet_Validator\"; useragentonly; nocase;"
