DMZ in Standard Mode

Click Advanced on the left side of the browser window, and then click DMZ Addresses.

Servers on the DMZ must have unique, valid IP addresses in the same subnet as the SonicWALL WAN IP Address. Your ISP should be able to provide these IP addresses, as well as information on setting up public servers.

To configure DMZ Addresses, complete the following instructions.

1.Enter the starting IP address of your valid IP address range in the From Address field.

2.Enter the ending IP address of your valid IP address range in the To Address field. Alert You can enter an individual IP address in the From Address field only.

3.Click Update. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the browser window.

If you receive an error when you click Update, confirm that the DMZ Address Range does not include the SonicWALL WAN IP Address, the WAN Gateway (Router) Address, or any IP addresses assigned on the One-to-One NAT or Intranet windows.

Tip The SonicWALL supports up to 64 DMZ address ranges.

DMZ in NAT Mode

The SonicWALL DMZ now has the ability to use private internal IP addresses rather than public IP addresses on the network. Since NAT hides the true IP addresses in use on the network, NAT on the DMZ is an additional security feature for the SonicWALL. The outside world only sees the outside public IP address of the DMZ and not the internal private addresses.

To configure the DMZ in NAT Mode, use the following instructions:

1.In the DMZ Private Address field, enter the private internal IP address assigned to the DMZ interface.

2.Assign a subnet mask in the DMZ Subnet Mask field. The LAN and DMZ can have the same subnet mask, but the subnets must be different. For instance, the LAN subnet can be 192.168.0.1 with a subnet mask of 255.255.255.0, and the DMZ subnet can be 172.16.18.1 with a subnet mask of 255.255.255.0.

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.
