•The SonicWALL WAN IP (NAT Public) Address is "10.1.1.25".

•The private SonicWALL LAN IP Address is "192.168.168.1".

•Computers on the LAN have private IP addresses ranging from "192.168.168.2" to "192.168.168.255".

In this example, "192.168.168.1", the SonicWALL LAN IP Address, is used as the gateway or router address for all computers on the LAN.

NAT with DHCP Client Configuration

The SonicWALL can receive an IP address from a DHCP server on the Internet. If your ISP did not provide you with a valid IP address, and instructed you to set your network settings to obtain an IP address automatically, enable NAT with DHCP Client. This mode is typically used with Cable and DSL connections.

To obtain IP settings dynamically, complete the following instructions.

1.Select NAT with DHCP Client from the Network Addressing Mode menu.

2.Enter a unique IP address from your LAN address range in the SonicWALL LAN IP Address field. The SonicWALL LAN IP Address is the address assigned to the SonicWALL LAN and is used for management of the SonicWALL.

3.Enter your network subnet mask in the LAN Subnet Mask field. The LAN Subnet Mask tells your SonicWALL which IP addresses are on your LAN. The default value, "255.255.255.0", supports up to 254 IP addresses.

4.Click Update. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the browser window. Restart the SonicWALL for these changes to take effect.

Alert! When NAT is enabled, designate the SonicWALL LAN IP Address as the gateway address for computers on the LAN.

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.
