Standard Configuration

If your ISP provided you with enough IP addresses for all the computers and network devices on your LAN, enable Standard mode.

To configure Standard addressing mode, complete the following instructions:

1.Select Standard from the Network Addressing Mode menu. Because NAT is disabled, you must assign valid IP addresses to all computers and network devices on your LAN.

2.Enter a unique, valid 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.Enter your WAN router or default gateway address in the WAN Gateway (Router) Address field. Your router is the device that connects your network to the Internet. If you use Cable or DSL, your WAN router is typically located at your ISP. If you use a router located at your site, use the IP address assigned to it.

5.Enter your DNS server IP address(es) in the DNS Servers field. The SonicWALL uses the DNS servers for diagnostic tests and for upgrade and registration functionality.

6.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.

NAT Enabled Configuration

Network Address Translation (NAT) connects your entire network to the Internet using a single IP address. Network Address Translation offers the following:

•Internet access to additional computers on the LAN. Multiple computers can access the Internet even if your ISP only assigned one or two valid IP addresses to your network.

•Additional security and anonymity because your LAN IP addresses are invisible to the outside world.

If your ISP hasn't provided enough IP addresses for all machines on your LAN, enable NAT and assign your network a private IP address range. You should use addresses from one of the following address ranges on your private network:

10.0.0.0- 10.255.255.255

172.16.0.0- 172.31.255.255

192.168.0.0 - 192.168.255.255

Tip If your network address range uses valid TCP/IP addresses, Internet sites within that range are not accessible from the LAN. For example, if you assign the address range 199.2.23.1 - 199.2.23.255 to your LAN, a Web server on the Internet with the address of 199.2.23.20 is not accessible.

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.
