How to Install SonicWall TZ370

Installing the TZ370 is designed to be straightforward for IT teams and value-conscious for managed service providers. Follow these general steps to bring your TZ370 online and protecting your network quickly:

• Plan and prepare: Identify the network topology where the TZ370 will be deployed, including WAN connections, LAN segments, wireless access points, and remote sites. Confirm licensing requirements for security services you want to enable (firewall, IPS, VPN, content filtering, etc.).
• Hardware and physical setup: Unbox the TZ370 and connect power, management console, and network interfaces as per your site plan. Place the appliance in a secure, well-ventilated location, close to the network edge where it can inspect traffic most effectively.
• Initial access and configuration: Access the management interface through the default IP address and follow the guided setup to configure basic network settings, admin credentials, and time synchronization. Establish administrator roles and define initial security policies aligned with your security posture.
• Define security services and policies: Enable essential services such as firewall, IPS, gateway antivirus, anti-spyware, URL filtering, and SSL/TLS inspection as needed. Create network rules, NAT policies, and VPN configurations for site-to-site and remote access, ensuring least-privilege access for users and devices.
• Connect and test VPNs and traffic flows: Configure VPN tunnels and verify connectivity between sites and remote clients. Validate that traffic is routed correctly through the TZ370, and run sanity checks on key applications to ensure performance and reliability remain at expected levels.
• Monitor and adjust: Use the centralized dashboard to monitor security events, throughput, and device health. Fine-tune security policies, refine IPS signatures, and adjust SSL inspection to balance security and user experience as your environment evolves.
