To restart the active SonicWALL, log into the primary SonicWALL LAN IP Address and click Tools on the left side of the browser window and then click Restart at the top of the window.

Click Restart SonicWALL, then Yes to confirm the restart. Once the active SonicWALL restarts, the other SonicWALL in the High Availability pair takes over operation.

Alert If the Preempt Mode checkbox has been checked for the primary SonicWALL, the primary unit takes over operation from the backup unit after the restart is complete.

Configuration Notes

•Changing Password - Do not change the password on the Backup firewall when it is in Idle con- dition. Changing the password prevents communication between the firewalls.

•If you are configuring the SonicWALL in Standard mode on the network, an additional IP address is necessary for the High Availability configuration.

•Auto Update - If Auto Update is enabled for firmware upgrades, the Primary SonicWALL should be upgraded first. And during the upgrade, the backup SonicWALL should be disconnected from the LAN or turned off. When the firmware upgrade is performed on the backup SonicWALL, the Primary SonicWALL should be disconnected from the network or turned off.

•Changes made to the backup SonicWALL do not get updated on the Primary SonicWALL until synchronization takes place between the two units.

Internet Security Appliances specifications

SonicWALL Internet Security Appliances are pivotal solutions aimed at safeguarding networks from an ever-evolving array of cyber threats. Designed for small to medium-sized businesses, as well as enterprises, these appliances deliver robust security and high-performance capabilities.

One of the main features of SonicWALL Internet Security Appliances is their Unified Threat Management (UTM) functionality. This integrated approach allows organizations to manage multiple security measures, including firewall protection, intrusion prevention systems (IPS), and antivirus capabilities, within a single device. This consolidation simplifies security management and reduces the risk of vulnerabilities from disparate systems.

Another significant technology found in these appliances is Application Control. This feature enables administrators to monitor and regulate the applications and services used within their networks, ensuring that bandwidth is allocated efficiently, and potentially harmful applications are blocked. Coupled with Content Filtering, SonicWALL offers granular policies to restrict access to inappropriate or non-work-related content, enhancing overall productivity while maintaining security.

SonicWALL appliances also utilize advanced cybersecurity technologies like SonicWall Capture Threat Assessment and Capture Advanced Threat Protection. These solutions leverage artificial intelligence to identify and remove sophisticated malware and ransomware threats before they infiltrate the network. This proactive approach ensures that only safe email and web traffic is allowed through, providing comprehensive protection against advanced persistent threats.

Moreover, SonicWALL’s Global Management System (GMS) enables centralized control over multiple security devices, making it easy for IT teams to maintain a consistent security posture across various locations. This capability is especially beneficial for organizations with distributed networks, as it provides real-time visibility into network activity and security incidents.

The appliances are also designed with scalability in mind. Whether an organization grows or needs to adjust its security policies, SonicWALL appliances can be updated, expanded, or modified without significant disruptions. This flexibility makes them a long-term investment for any business focused on network security.

In addition, SonicWALL's user-friendly interface simplifies the deployment and management processes. With intuitive dashboards and reporting tools, administrators can easily track security events, analyze network traffic patterns, and respond swiftly to potential threats.

In summary, SonicWALL Internet Security Appliances combine essential features like Unified Threat Management, Application Control, and advanced threat protection technologies into a cohesive security solution. Their scalability, centralized management capabilities, and user-friendly interfaces make them an excellent choice for businesses aiming to strengthen their cyber defenses in a complex digital landscape.
