This dot is not a special character but a way to say any single character. And as the regex reference guide that we found yesterday in the Term services guide says: Asterisk matches zero or more sequences of the character preceding the asterisk. Also acts as a wildcard for matching any number of characters So my reasoning was that the string "probe" can be sent as a standalone string or prepended and appended with different characters which I tried to define with dot and asterisk And Ta-Da!!! I made a slight typo, my regex should have been (see the prepending sequence) .*[Pp][Rr][Oo][Bb][Ee].* And ASA tested it OK !

I tried to test the regex that matches all combinations of the string "probe". The solution guide says it should be like this: *.[Pp][Rr][Oo][Bb][Ee].* I tried to test it on ASA and it failed until I removed asterisks and dots.
