Hi Ivan The only difference between a NAS1 and NAS2 is because the first NAS1 have installed a module that allows digital modems set the user's account to a phone number, while the NAS2 has a module with analog modems that do not allow this. Equally be used both for serving Dialin. I removed the setting Auth-Type from the beginning. Now, if you look though the difference for this user when you connect both NAS, they assigned different IP that are not in the same block. besides that one checks the telephone number from which you are connected, the other by the type of technology. My question is how could accommodate all on one line, I mean to avoid having to repeat the same user twice with different parameters? I think the state is more flexible configuration of my users in the users file for this type of scheme, I can not even see it in a mysql database. could show if possible, an example would be like mysql? ---------------------------------------------- Webmail, servicio de correo electronico Casa de las Americas - La Habana, Cuba.
