I can't find any clue as to the maximum length of this PSK. Nor what characters it can include.

Tried 64 characters, including Upper, Lower, Digits, Specials and got the unhlpful, and ungramatical error box: "The dial in Preshared Key error".

On a similar note, what are the rules for a Remote Dial-in user password? The form does helpfully say 19 characters max but not what type of character. Seems not to work if special characters are included (although no error is given if you include specials - the login just doesn't work).

TIA.

[later] Seems like [up to] 64 alphanumerics is ok but specials are not supported
