Adding, Modifying And Deleting Destination Networks; Radius And Xauth Authentication - Dell SonicWALL GX250 Manual

Adding, Modifying and Deleting Destination Networks

You may add, modify or delete destination networks. To add a second destination
network, click Add New Network... and define the Network and Subnet Mask
fields of the second network segment. To modify a destination network, click the
Notepad icon to the right of the appropriate destination network entry. Then modify
the appropriate fields and click Update to update the configuration. To delete a
destination network, click the Trash Can icon to the far right of the appropriate
destination network entry and then click OK to confirm the removal.
Modifying and Deleting Existing Security Associations
The Security Association menu also allows you to modify and delete existing
Security Associations. To delete an SA, select it from the menu and click the Delete
This SA button. To modify an SA, select it from the menu, make the desired
changes, and click Update. Once the SonicWALL has been updated, a message
confirming the update is displayed at the bottom of the Web browser window. Click
Update to enable the changes.
Accessing Remote Resources across a Virtual Private Network
SonicWALL VPN Clients, which cannot transmit NetBIOS broadcasts, may access
resources across a VPN by locating a remote computer by IP address. For example, if
a remote office has a Microsoft SQL server, users at the local office may access the SQL
server by using the server's private IP address.
There are several ways to facilitate connecting to a computer across a SonicWALL VPN:
• Use the Find Computer tool
• Create a LMHOSTS file in a local computer's registry
• Configure a WINS Server to resolve a name to a remote IP address.

Radius and Xauth Authentication

An IKE Security Association may be configured to require RADIUS authentication
before allowing VPN clients to access LAN resources. This authentication provides an
additional layer of VPN security while simplifying and centralizing management.
RADIUS authentication allows many VPN clients to share the same VPN configuration,
but requires each client to authenticate with a unique user name and password. And
because a RADIUS server controls network access, all employee privileges may be
created and modified from one location.
Note: SonicWALL's RADIUS implementation supports Steel-Belted RADIUS by Funk
Software. A 30-day demo version of Steel-Belted RADIUS may be downloaded from
<http://www.funk.com>.
To enforce RADIUS authentication, complete the following instructions.
