Description
The One-Touch Configuration Override, this feature can be thought of as a quick tune-up for SonicWall network security appliance’s security settings.
With a single click, One-Touch Configuration Override applies over sixty configuration settings to implement SonicWall’s recommended best practices. This is applicable for both DPI and Stateful Firewall Security and Stateful Firewall security.
Resolution
There is a set of One-Touch Configuration Override option available on the SonicWall.It can be thought of us as a quick tune-up for your SonicWall appliance's security settings. With a single click, One-Touch Configuration Override applies over sixty configuration settings over sixteen pages of the SonicWall GUI to implement SonicWall's recommended best practices. These settings ensure that your appliance is taking advantage of SonicWall's security features.
There are two sets of One-Touch Configuration Override settings:
- DPI and Stateful Firewall Security For network environments with Deep Packet Inspection (DPI) security services enabled, such as Gateway Anti-Virus, Intrusion Prevention, Anti-Spyware, and App Rules.
- Stateful Firewall Security For network environments that do not have DPI security services enabled, but still want to employ SonicWall's Stateful firewall security best practices.
To see details of the settings that will be impacted, click on the Preview applicable changes link next to each button. A page displays with a list of each setting and the value to which it will be set.

CAUTION: A system restart is required for the updates to take full effect. The Administrator should review the settings before applying it on appliance.
