Per nas simultaneous-use limit

Hi all, We want to per user limit login to 4 for particular NAS. I added following in users: DEFAULT Huntgroup-Name == "broadband", Simultaneous-Use := 4 Fall-Through = Yes And in huntgroups: broadband NAS-IP-Address == 192.168.192.201 broadband NAS-IP-Address == 192.168.192.204 Is seems the limit of 4 is for all users in the same NAS instead of particular users. We're using 2.2.0. Would anyone advise? Thanks lot. Rgds, /st
