Users
Extensive features are available on the Users tab in the Access section of the Management
interface. User level access can be configured for authentication and access to the network.
Authentication can be performed using a local user database, RADIUS, or a combination of the two
applications.
For instructions on configuring individual users on RADIUS servers, see Appendix I.
Currently, when a VPN tunnel is established between two SonicWALL appliances, any users residing
on the local LAN of each SonicWALL can send data across the VPN. In some cases, complete user
access could be a security risk, and only authenticated users access the VPN tunnel and send data
across the network.
Global User Settings
• Time users out after 5 minutes of inactivity - Enter the number of allowable inactivity minutes
before a user is automatically logged out of the network via the SonicWALL.
• Limit login session time to - Limit the length of time, in minutes, that a user is allowed to be
logged into the network via the SonicWALL. When a user logs into the SonicWALL using a
username and password, the user can also set the maximum login session time, but LAN it
cannot be longer than the time configured by the administrator. If Limit login session time to is
not selected, then the user has unlimited login session time on the SonicWALL.
• Allow DNS access for unauthenticated VPN users - Enabling this check box allows
unauthenticated DNS traffic to access the DNS server over a VPN tunnel with authentication
enforcement. Use this checkbox if you allow unauthenticated users to access the DNS server
on your LAN.
