Corporate SonicWALL

WAN IP Address: 66.120.118.11

WAN IP Address:66.120.118.25

Subnet Mask: 255.255.255.0

Subnet Mask: 255.255.255.0

LAN IP Address 192.168.1.1

LAN IP Address: 192.168.3.1

Subnet Mask: 255.255.255.0

Subnet Mask: 255.255.255.0

VPN Single Armed Mode SonicWALL

 

WAN IP Address: 66.120.118.13

 

Subnet Mask: 255.255.255.0

 

LAN IP Address: 192.168.2.1

 

Subnet Mask: 255.255.255.0

 

To configure a SonicWALL in VPN Single Armed Mode in front of an existing SonicWALL, follow these steps.

1.Configure the Remote and Corporate SonicWALLs in your preferred networking mode.

2.Configure a VPN SA using IKE and Pre-shared Secret on the Remote SonicWALL using the VPN SonicWALL WAN IP address, 66.120.118.13, as the IPSec Gateway, and the Corporate SonicWALL WAN IP address, 66.120.118.25, as the Destination Network.

3.Configure a Static Route on the Local SonicWALL to send network traffic destined for the Remote SonicWALL to the VPN SonicWALL.

4.Configure the VPN SonicWALL in Standard networking mode.

5.Click Advanced, then Intranet. Select the VPN Single Armed Mode (stand alone VPN gateway) checkbox, and click Update. A rule is automatically added to the VPN SonicWALL for HTTPS management from the WAN. The LAN port is disabled when you configure a SonicWALL for VPN Single Armed mode.

6.Configure a VPN SA using IKE and Pre-shared Secret on the VPN SonicWALL to securely connect to the Remote SonicWALL. Enter the Remote SonicWALL WAN IP address as the IPSec Gateway and the Remote SonicWALL LAN IP Address range as the Destination Network, if configuring “Many to One NAT”.

7.Click Advanced, and then Routes. Enter the Corporate SonicWALL WAN IP address in the Dest. Network field. Enter the subnet mask in the Subnet Mask field. Enter the Local SonicWALL WAN IP address as the Gateway, and select WAN from the Link menu. Click Update.

Now that all SonicWALLs are configured, network traffic on the corporate SonicWALL destined for the remote office is routed to the VPN SonicWALL, encrypted, and sent to the remote SonicWALL.

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.
