Primary Interface

The SonicWALL TELE3 SP automatically detects if a WAN Ethernet connection exists when the SonicWALL is powered on. Because it can automatically detect the Ethernet connection, the Primary Interface is Ethernet.

Failover Settings

You can enable WAN failover for the SonicWALL by configuring settings in this section. Select Enable WAN Failover to use this feature on the SonicWALL. The Secondary Interface Setting defaults to Modem.

Preempt Mode

Select Preempt Mode if you want the TELE3 SP to re-establish the connection to the WAN Ethernet interface after a connection failure on the WAN Ethernet port.

Probing on the TELE3 SP

Probing for WAN connectivity occurs over the Ethernet connection, the dial-up connection, or both. When probing is disabled on the Ethernet link, the SP only performs link detection. If the Ethernet connection is lost for a duration of 5-9 seconds, the SP considers the Ethernet connection to be unavailable. If the Ethernet link is lost for 0-4 seconds, the SP does not consider the connection to be lost. If you are swapping cables quickly, unnecessary WAN failover does not occur on the SP. If probing is enabled and the cable is unplugged, the 5-9 seconds link detection does not occur. Instead, the probing rules apply to the connection using the parameters configured for Probe Interval Time and number of Missed Probes. If probing is enabled on Dial-up, the dial-up connection is terminated and re-established when probing fails over the modem.

Use the following instructions to configure the Failover Settings:

1.Select Enable WAN Failover.

2.Select Enable Probing.

3.Select an option from the Probe Through menu. Select Ethernet Only to probe the Ethernet WAN connection and failover to the modem when the connection is lost. Select Modem Only to probe a dial-up connection and have the modem redial when the dial-up connection is lost. Select Modem and Ethernet to enable both types of probing on the SP.

4.Enter the IP address for the probe target in the Probe Target (IP Address) field. The Probe IP address is a static IP address on the WAN. If this field is left blank, or 0.0.0.0 is entered as the address, the Probe Target is the WAN Gateway IP address.

Tip The probe is a ping sent to the IP address and is used, along with the response, as a method of determining Internet connectivity.

5.In the Probe Interval (seconds) field, enter the amount of time between probes to the Probe Target. Five (5) seconds is the default value. To deactivate the Probe Detection feature, enter zero (0) as the value. In this case, the WAN Failover only occurs when loss of the physical WAN Ethernet connection occurs on the TELE3 SP.

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.
