LAN Settings

•NAT with L2TP Client mode uses IPSec to connect a L2TP server and encrypts all data transmitted from the client to the server. However, it does not encrypt network traffic to other destinations.

•NAT with PPTP Client mode uses Point to Point Tunneling Protocol (PPTP) to connect to a remote server. It supports older Microsoft implementations requiring tunneling connectivity.

•SonicWALL LAN IP Address

The SonicWALL LAN IP Address is the IP address assigned to the SonicWALL LAN port. It is used for managing the SonicWALL. This IP address should be a unique address from the LAN address range.

•LAN Subnet Mask

The LAN Subnet Mask defines which IP addresses are on the LAN. The default Class C subnet mask of "255.255.255.0" supports up to 254 IP addresses on the LAN. If the Class C subnet mask is used, all local area network addresses should contain the same first three numbers as the SonicWALL LAN IP Address--for example, "192.168.168."

Multiple LAN Subnet Mask Support

Alert This feature does not replace or substitute configuring routes with the Routes tab in the Advanced section of the SonicWALL. If you have to define a subnet on the other side of a router, you must define a static route using the Routes tab in the Advanced section.

Multiple LAN Subnet Mask Support facilitates the support of legacy networks incorporating the SonicWALL, and makes it easier to add additional nodes if the original subnet is full. Before you can configure multiple local LAN subnets in the SonicWALL, you must have the following information:

•Network Gateway Address - This is an IP address assigned to the SonicWALL in addition to the existing LAN IP address. If you have configured your SonicWALL in Standard mode, the IP address should be the Default Gateway IP address assigned to your Internet router on the same subnet. All users on the subnet you are configuring must use this IP address as their default router/gateway address.

•Subnet Mask - This value defines the size, and based upon the Network Gateway entry, the scope of the subnet. If you are configuring a subnet mask that currently exists on the LAN, enter the existing subnet mask address into the Subnet Mask field. If you are configuring a new subnet mask, use a subnet mask that does not overlap any previously defined subnet masks.

Alert The SonicWALL cannot be managed from any of the additional Network Gateway addresses. You must use the IP address set as the LAN IP address of the SonicWALL. Also, you cannot mix Standard and NAT subnets behind the SonicWALL.

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.
