DI-206 ISDN Remote Router

Authentication

should be added to the client file. The Client Name field in the file
gives the IP address of the DI-206, and the Key field should be the
same as the Key field in the Radius Configuration submenu.
After a RADIUS server has been configured, the DI-206 will use it to
authenticate all users instead of checking it’s internal Dial-Up User
Profile.
Adding Users to the RADIUS Database
The DI-206 only uses the RADIUS database for user authentication.
Except for the User Name, Password and Framed_IP_Address fields,
most standard RADIUS attribute fields are ignored by the DI-206.
To add a user to the RADIUS database, edit the users file in the
RADIUS server’s /etc/raddb directory, and add a line similar to
the following:
joeuser Password = “joepassword”
Each user should have a user name/password record in the Users
database. It is also possible to configure an IP address for each user by
adding a line in the Users database similar to the following:
Ip user Password = “iusespecificip”,
Framed_IP_Address = 192.168.0.117
