Public LAN Server

A Public LAN Server is a LAN server designated to receive inbound traffic for a specific service, such as Web or e-mail. You can define a Public LAN Server by entering the server's IP address in the Public LAN Server field for the appropriate service. If you do not have a Public LAN Server for a service, enter "0.0.0.0" in the field.

Windows Networking (NetBIOS) Broadcast Pass Through

Computers running Microsoft Windows communicate with one another through NetBIOS broadcast packets. By default, the SonicWALL blocks these broadcasts. If you select From LAN to WAN, your SonicWALL allows NetBIOS broadcasts from LAN to DMZ or from LAN to WAN. Then, LAN users are able to view machines on the DMZ and the WAN in their Windows Network Neighborhood.

Windows Messenger Support

Select Enable Support if you are having problems using Windows Messenger through the SonicWALL. If Enable Support is selected, it may affect the performance of the SonicWALL.

Detection Prevention

Enable Stealth Mode

By default, the SonicWALL responds to incoming connection requests as either "blocked" or "open". If you enable Stealth Mode, your SonicWALL does not respond to blocked inbound connection requests. Stealth Mode makes your SonicWALL essentially invisible to hackers.

Randomize IP ID

A Randomize IP ID check box is available to prevent hackers using various detection tools from detecting the presence of a SonicWALL appliance. IP packets are given random IP IDs which makes it more difficult for hackers to “fingerprint” the SonicWALL appliance. Use this check box for additional security from hackers.

Network Connection Inactivity Timeout

If a connection to a remote server remains idle for more than five minutes, the SonicWALL closes the connection. Without this timeout, Internet connections could stay open indefinitely, creating potential security holes. You can increase the Inactivity Timeout if applications, such as Telnet and FTP, are frequently disconnected.

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.
