Configuration Tab

The Configuration tab allows you to enable the WFS Acceleration service and select a public IP address for the WXA series appliance.

Figure 85:35 Configuration Tab

Name	Description
Enable WFS Acceleration Checkbox	Enables (checked) the WFS Acceleration service on the WXA series appliance. Enabled by default.
‘Public’ WFS Acceleration Address Drop-down	Sets the address object that represents the IP address that the SonicWALL WXA series appliance will use when connecting to servers and clients.
Apply Changes Button	Applies the latest configuration settings.

Note You can verify the WFS Acceleration status on the WAN Acceleration > Status page in the WFS Acceleration Panel.

Domain Details Tab

The Domain Details tab allows you to configure the SonicWALL WXA series appliance to match that of the Microsoft Windows Domain it is to join. The SonicWALL WXA series appliance may automatically discover the domain details if the DNS server configured on the SonicWALL NSA/TZ series appliance is a domain controller and the DNS server is correctly configured in the domain.

Note The user interface is different if the domain name is not auto-discovered. This requires you to enter the basic details for a domain in a different table.

Domain Details (Name Auto-discovered)

Name	Description
Autodiscovered Domain Panel
Fully Qualified Domain Name:	The fully qualified domain name (FQDN) for the Windows domain that the SonicWALL WXA series appliance uses for file sharing. To change the FQDN, you must unjoin the domain. Click the Edit button to modify the FQDN, Configure Domain Pop-up Window.
Domain Joined:	The FQDN of the domain that the SonicWALL WXA series appliance is part of. Initially entered when setting up the Domain Details, Configure Domain Pop-up Window
NETBIOS Domain:	If you configured the FQDN at initial setup, the SonicWALL WXA series appliance should auto-discover the corresponding NETBIOS domain. Click the Edit button to configure the FQDN and the NETBIOS Domain, Configure Domain Pop-up Window. Note Changing the FQDN or the NETBIOS Domain after joining the Windows domain requires the device to rejoin the domain.
Hostname:	Displays the hostname for the SonicWALL WXA series appliance. If an account is created on the domain using the SonicWALL WXA series appliance hostname, the SonicWALL WXA series appliance attempts to join the domain. Click the Edit button to modify the hostname, Configure Hostname Pop-up Window Note Changing the hostname requires the old computer account to be manually deleted from the domain controller.
Kerberos Server:	The FQDN of the Kerberos server on the Windows Domain. The port number defaults to 88. This server is typically the domain controller. To edit the server name, you must first unjoin the domain, and then click the Edit button. The Kerberos Server pop-up window appears, Configure Kerberos Server Pop-up Window.
LDAP Server:	Sets the Lightweight Directory Access Protocol (LDAP) server on the network. The port number defaults to 389. This server is typically the domain controller.
Joined Domain: Checkbox	(Read-only) Indicates the device has joined the domain. If this option is not check but the other checkboxes are, refer to Troubleshooting WFS Acceleration.
Machine Account Exists: Checkbox	(Read-only) Indicates an account matching the hostname of the device is found on the domain. There are three pre-requisites before the SonicWALL WXA series appliance can join the domain: The Machine Account Exists is the only checkbox enabled. SELF must be delegated to join the domain, The computer account password is set to the authorization code. When an account is created on the domain using the devices hostname, the device discovers the domain and should configure itself.
Trusted for Delegation: Checkbox	(Read-only) Indicates that the computer account of the SonicWALL WXA series appliance on the Domain Controller is trusted for delegation. When this checkbox is checked, the computer account IS trusted for delegation. This is a necessity and requires the administrator to configure the domain controller to confirm that the SonicWALL WXA series appliance can be trusted for delegation.
Other Device Settings Panel
Time Synchronization Source:	Displays the server that the SonicWALL WXA series appliance will synchronized its clock with. This server is usually the Domain Control because the SonicWALL WXA series appliance must closely match that of the Domain Controller. Click the Edit button to modify the server, Time Synchronization Pop-up Window.
Primary DNS Server:	(Read-only) Displays the current primary DNS server IP address, which must be a domain DNS server for WFS Acceleration to function properly.
Secondary DNS Server:	(Read-only) Displays the current secondary DNS server IP address.
Action Buttons
Advanced Options	Configures the WFS Acceleration service in more detail with Client Signing, Server Signing, and Max Transmit, which affect the CIFS packet size, Advanced Options Pop-up Window.
Join Domain	The SonicWALL WXA series appliance joins the domain (becomes part of the domain) that is identified in the FQDN. The Join Domain Pop-up Window is displayed, Join Domain Pop-up Window. If the SonicWALL WXA series appliance has previously joined the domain, the Rejoin Domain button is displayed.
Unjoin Domain	Removes all information about the current domain that the SonicWALL WXA series appliance has joined.
Test Configuration	Tests the WFS Acceleration service. If the WFS Acceleration service is not working correctly, reconfigure the domain details, and then retest.
Flush Cache	Clears all data stored in the cache.
Restart WFS	Restarts the WFS Acceleration service. Note All existing sessions and file transfers will be terminated.

Note You must create a new SPN alias if there are two or more DNS servers.
Default Cache Enabled: Checkbox	When enabled (checked) shares are stored in the default cache. This option is enabled by default. When a file is requested, that is also available in the cache, the SonicWALL WXA series appliance serves the data from that cache as long as the cache file is valid. If the original file has changed, the parts of the cache that are still valid may be used. This process reduces the need for data to be sent over the network. This option can be overridden for individual shares.
Default Cache Read Ahead: Text Field (Add Server Pop-up only)	The default size (measured in bytes) for read-ahead speed in the cache. To calculate this value, multiply the link latency (in milliseconds) by the measured site-to-site bandwidth in (kilobytes per second) and divide that by the number of simultaneous file access users.
