The Connections section provides the ability to fine-tune the firewall to prioritize for either optimal throughput or an increased number of simultaneous connections that are inspected by Deep-Packet Inspection (DPI) services. There is no change in the level of security protection provided by these DPI Connections settings.

•
|
Maximum SPI Connections (DPI services disabled) - This option does not provide SonicWALL DPI Security Services protection and optimizes the firewall for maximum number of connections with only stateful packet inspection enabled. This option should be used by networks that require only stateful packet inspection, which is not recommended for most Dell SonicWALL network security appliance deployments.

|
•
|
Maximum DPI Connections (DPI services enabled) - This is the default and recommended setting for most Dell SonicWALL network security appliance deployments.
|
|
•
|
DPI Connections (DPI services enabled with additional performance optimization) - This option is intended for performance critical deployments. This option trades off the number of maximum DPI connections for an increased firewall DPI inspection throughput.
|
|
NOTE: When changing any Connections setting, the Dell SonicWALL security appliance must be restarted for the change to be implemented.
|
The maximum number of connections also depends on whether App Flow is enabled and if an external collector is configured, as well as the physical capabilities of the particular model of Dell SonicWALL security appliance. Mousing over the Question Mark icon next to the Connections heading displays a pop-up table of the maximum number of connections for your specific Dell SonicWALL security appliance for the various configuration permutations. The table entry for your current configuration is indicated in the table.
