NAS List
A NAS (Network Access Server) is a router or BNG that your subscribers connect through, for example a MikroTik, Cisco or Huawei router. The NAS asks SAS Radius whether a user may connect (authentication), reports the user's traffic (accounting), and receives disconnect and speed-change requests from SAS Radius.
Every router that sends RADIUS requests to SAS Radius must be added as a NAS. Requests from an IP address that is not in the NAS list are ignored.

Actions
| Action | Description |
|---|---|
| New | Add a NAS. See Adding and Editing a NAS. |
| Delete | Delete the selected NAS device(s). See below. |
To edit a NAS, click its name.
Deleting a NAS
Select one or more NAS devices, click Actions → Delete and confirm. Users who are online on that router are not disconnected, but SAS Radius no longer accepts logins or accounting from it.
Adding, editing or deleting a NAS restarts the RADIUS service. Logins and accounting stop for a few seconds, so avoid making many NAS changes at peak hours.
