Me contesto a mí mismo... Me hacía falta definir en el config.php la
directiva logtimezone de owncloud:
'logtimezone' =>
Para que ponga la hora acorde a mi zona horaria, por eso fail2ban era
incapaz de poner la regla, no coincidia la hora.
Ahora sí que bloquea y sí que aparece...
Chain fail2ban-owncloud-login (1 references)
target prot opt source destination
DROP all -- 192.168.0.33 0.0.0.0/0
Gracias.
Saludos.
