10.Select a VPN encryption method from the Phase 2 Encryption/Authentication menu. Since data throughput and security are the primary concern, select Encrypt and Authenticate (ESP 3DES HMAC SHA1).

11.Define a Shared Secret. Write down this key as it is required when configuring the San Francisco Office SonicWALL TELE3.

12.Click Add New Network... to open the VPN Destination Network window and enter the destination network addresses.

13.Enter the IP address and subnet mask of the destination network, the San Francisco office, in the Network and Subnet Mask fields. Since NAT is enabled at the San Francisco office, enter a private LAN IP address. In this example, enter "192.168.1.1" and subnet mask "255.255.255.0." Click OK to add the destination network address.

Alert The Destination Network Address must NOT be in the local network address range. Therefore, the San Francisco and Chicago offices must have different LAN IP address ranges.

14. Click Advanced Settings. Select the following boxes that apply to your SA:

•Enable Keep Alive - if you want to maintain the current connection by listening for traffic on the network segment between the two connections.

•Enable Windows Networking (NetBIOS) broadcast - if remote clients use Windows Network Neighborhood to browse remote networks.

•Apply NAT and firewall rules - to apply NAT and firewall rules to the SA or just firewall rules if in Standard mode.

•Forward packets to remote VPNs - if creating a “hub and spoke” network configuration

•Enable Perfect Forward Secrecy - if you want to add another layer of security by adding an ad- ditional Diffie-Hellman key exchange.

•Phase 2 DH Group - select the type of DH key exchange in Phase 2 for Perfect Forward Secrecy.

•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 Update to add the Security Association. Once the SonicWALL PRO 200 is updated, a message confirming the update is displayed at the bottom of the browser 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.
