begins to count IP addresses against the license, and continues to count new LAN IP addresses accessing the Internet until the appliance is rebooted.

When a computer or other device connects to the LAN port of the SonicWALL, it is detected via broadcast and stores the computer or other device IP address in memory. If 5, 10, or 50 IP addresses have been stored in the SonicWALL, the SonicWALL does not permit any additional machines to access the Internet. Therefore, the SonicWALL restricts the number of IP addresses on the LAN, not the number of simultaneous connections to the Internet.

If you have fewer than the maximum number of computers or other devices on your LAN, but it appears that the IP license limit is exceeded, download a Tech Support Report and review the devices with IP addresses. Rogue devices such as printers are filling up the SonicWALL IP address limit. Tech Support Reports are explained in the Tools chapter of this manual.

Additionally, computers with two (2) Network Interface Cards (NIC) can take up two IP addresses. You must reconfigure your network to avoid these problems by turning off IP forwarding on Windows® NT or Windows2000® servers using two NICs.

If devices on the LAN receive IP addresses from a DHCP server, see the DHCP chapter of this manual.

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.
