# NAS List

A **NAS** (Network Access Server) is a router or BNG that your subscribers connect through, for example a MikroTik, Cisco, Huawei, UBNT Access Point, Ubiquiti EdgeRouter, Nokia Routers. 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.

Open *NAS* in the menu to see the list.

- The **Search** box matches part of the name or IP address.
- **Export** creates an Excel file in the background; download it from *Reports → Data Export Jobs* (needs *NAS - Export*).
- A manager assigned to a **Site** sees only the NAS devices of that site.

## Actions

<table id="bkmrk-actiondescription-ne"><thead><tr><th>Action</th><th>Description</th></tr></thead><tbody><tr><td>New</td><td>Add a NAS. See [Adding and Editing a NAS](https://help.snono-systems.com/books/sas-radius/page/adding-and-editing-a-nas).</td></tr><tr><td>Delete</td><td>Delete the selected NAS device(s).

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.

<p class="callout warning">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.</p>
