6.Define an SPI that the local SonicWALL uses to identify the Security Association in the Outgoing SPI field.SPIs should range from 3 to 8 characters in length and include only hexadecimal characters.

Alert Each Security Association must have unique SPIs; no two Security Associations can share the same SPIs. However, each Security Association Incoming SPI can be the same as the Outgoing SPI.

7.Select an encryption algorithm from the Encryption Method menu. Enter a 16-character hexadecimal key in the Encryption Key field if you are using DES or ARCFour encryption. Enter a 48-character hexadecimal key if you are using Triple DES encryption. This encryption key must match the remote SonicWALL's encryption key.

When a new SA is created, a 48-character key is automatically generated in the Encryption Key field. This can be used as a valid key for Triple DES. If this key is used, it must also be entered in the Encryption Key field in the remote SonicWALL. If Tunnel Only (ESP NULL) or Authenticate (AH MD5) is used, the Encryption Key field is ignored.

8.Enter a 32-character, hexadecimal key in the Authentication Key field.

When a new SA is created, a 32-character key is automatically generated in the Authentication Key field. This key can be used as a valid key. If this key is used, it must also be entered in the Authentication Key field in the remote SonicWALL. If authentication is not used, this field is ignored.

9.Click Add New Network... to enter the destination network addresses. Clicking Add New Network... automatically updates the VPN configuration and opens the VPN Destination Network window.

10.Enter the beginning IP address of the remote network address range in the Range Start field. If NAT is enabled on the remote SonicWALL, enter a private LAN IP address. Enter "0.0.0.0" to accept all remote SonicWALLs with matching encryption and authentication keys.

11.Enter the ending IP address of the remote network's address range in the Range End field. If NAT is enabled on the remote SonicWALL, enter a private LAN IP address. Enter "0.0.0.0" to accept all remote SonicWALLs with matching encryption and authentication keys.

12.Enter the remote network subnet mask in the Destination Subnet Mask for NetBIOS broadcast field if Enable Windows Networking (NetBIOS) Broadcast is selected. Otherwise, enter "0.0.0.0" in the field.

13.Click Update to add the remote network and close the VPN Destination Network window. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the browser window.

14.Click Advanced Settings and check the boxes that apply to your SA:

Enable Windows Networking (NetBIOS) broadcast - if the 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.

Route all internet traffic through this SA - if forcing internet traffic from the WAN to use this SA to access a remote site.

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.
