NAT with DHCP Client

NAT with DHCP Client is a networking mode that allows you to obtain an IP address for a specific length of time from a DHCP server. The length of time is called a lease, which is renewed by the DHCP server typically after a few days. When the lease is ready to expire, the client contacts the server to renew the lease. This is a common network configuration for customers with cable or DSL modems. You are not assigned a specific IP address by your ISP.

Instructions for configuring NAT with DHCP Client mode begin on page 32.

NAT with L2TP Client

NAT with L2TP Client is a networking mode that allows you to connect to a remote L2TP server to obtain IP address settings. L2TP (Layer 2 Tunneling Protocol) is a network protocol using IPSec to encrypt transmitted data, and is only supported by Windows 2000. If you are running other versions of Windows, you must use PPTP as your tunneling protocol.

Instructions for configuring NAT with L2TP Client mode begin on page 37.

NAT with PPTP Client

NAT with PPTP Client is a networking mode supporting PPTP (Point to Point Tunneling Protocol) to connect to a remote server. It uses Microsoft Point to Point Encryption (MPPE) to provide encryption of transmitted data. PPTP typically supports older Microsoft clients that require tunneling connectivity or situations in which a tunnel passes through a firewall performing NAT.

Configuring the SonicWALL in Standard Mode

This section describes configuring the SonicWALL in Standard mode. You must have a single, static IP address to begin configuration. Follow the instructions below.

TIP Be sure to have your network information including your WAN IP address, subnet mask, and DNS settings ready. This information is obtained from your ISP.

1.Open a Web browser and enter the default SonicWALL IP address, 192.168.168.168, in the Location or Address field.

2.The Login window appears. Enter admin in the User Name field, and password in the Password field.

3.Click Cancel on the initial Installation Wizard page to cancel the wizard.

4.Click Network in the General section.

5.Select Standard from the Network Addressing Mode menu.

6.Enter 192.168.168.1 in the SonicWALL LAN IP Address field.

7.Enter 255.255.255.0 in the LAN Subnet Mask field.

8.Enter your WAN router or default gateway IP address in the WAN Gateway (Router) Address field. If you have DSL or cable, your WAN router is typically located at your ISP.

9.Enter your DNS IP address(es) in the DNS Server fields.

10.Click Update. Once the SonicWALL is updated, you must restart the SonicWALL for the changes to take effect.

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.
