Default LAN Gateway if specifying the IP address of the default LAN route for incoming IPSec packets for this SA. This is used in conjunction with the Route all internet traffic through this SA check box.

VPN Terminated at LAN, DMZ, or LAN/DMZ- select one of the three terminating points for the VPN tunnel.

15. Click OK to close the Advanced Settings window. Then click Update to update the SonicWALL.

Configuring the Second SonicWALL Appliance

To configure the second SonicWALL appliance, follow the same configuration steps as the first SonicWALL. You must enter the same SPIs and Encryption keys as the first SonicWALL appliance into the settings of the second SonicWALL appliance.

Example of Manual Key Configuration for Two SonicWALLs

Widgit, Inc. wants to connect their main office with a branch office on the East Coast. Using a SonicWALL PRO 300 and a TELE3, they can configure a secure VPN tunnel between the two sites. The main office has the following network settings:

•SonicWALL LAN IP address - 192.168.11.1

•LAN subnet mask - 255.255.255.0

•WAN router address - 209.33.22.1

•SonicWALL WAN IP address - 209.33.22.2

•WAN subnet mask - 255.255.255.224

The remote office has the following network settings:

•SonicWALL LAN IP address - 192.168.22.222

•LAN subnet mask - 255.255.255.0

•WAN router address - 207.66.55.129

•SonicWALL WAN IP address - 207.66.55.130

•WAN subnet mask - 255.255.255.248

To configure the main office PRO 300, use the following steps:

1.Configure the network settings for the firewall using the Network tab located in the General section.

2.Click Update and restart the SonicWALL if necessary.

3.Click VPN, then the Configure tab.

4.Create a name for the main office SA, for example, Main Office.

5.Enter the remote office WAN IP address for the IPSec Gateway Address.

6.Create an Incoming SPI using alphanumeric characters.

7.Create an Outgoing SPI using alphanumeric characters.

8.Select Strong Encrypt (ESP 3DES) as the Encryption Method.

9.Write the Encryption Key down or use cut and paste to copy it to a Notepad window.

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.
