Chapter 8 RADIUS The following table describes the labels in this screen. Table 12 ADVANCED > RADIUS LABEL DESCRIPTION RADIUS Setup Select Disable if you will not use an external RADIUS server to authenticate subscribers. Select Enable to use an external RADIUS server to authenticate subscribers. You may also use an external RADIUS server to perform accounting for the subscriber accounts. Accumulation Note: Disabling authentication in the AUTHENTICATION screen also disables authentication via an external RADIUS server, regardless of what you set here. Select this option to allow each subscriber multiple re-login until the time allocated is used up. Idle Time Out This applies to subscribers that are authenticated by the RADIUS server; the setting in the BILLING screen applies to subscribers that are authenticated by the built-in authentication. You must also enable the accounting service below. The N4100 automatically disconnects a computer from the network after a period of inactivity. The subscriber may need to enter the username and password again before access to the network is allowed. Time to Finish Specify the idle timeout between 1 and 1440 minutes. The default is 5 minutes. Select this option to allow each subscriber a one-time login. Once the subscriber logs in, the system starts counting down the pre-defined usage even if the subscriber stops the Internet access before the time period is finished. If a subscriber disconnects and reconnects before the allocated time expires, the subscriber does not have to enter the user name and password to access the Internet again. This applies to subscribers that are authenticated by the RADIUS server; the setting in the BILLING screen applies to subscribers that are authenticated by the built-in authentication. You must also enable the accounting service below. Primary RADIUS Server Server IP/ Enter the IP address or the domain name of the RADIUS server.

Accounting Port Enter the port number that the RADIUS server uses for accounting. You only need to change this value from the default if your network administrator gave you a specific port number to use. The allowed numbers are from 0 to 65535. N4100 User's Guide 95
