How to Install SonicWall TZ370

Installing the TZ370 is designed to be straightforward for IT teams and network administrators. Follow these general steps to deploy a secure, high-performance firewall in your environment:

• Prepare the environment: Unbox the TZ370 and verify power requirements. Determine the proper placement (network closet or data cabinet) and plan for cable management, ventilation, and accessibility for management tasks. Confirm you have appropriate network cables and, if needed, VLAN tagging configurations ready.
• Connect the hardware: Power on the device and connect WAN and LAN interfaces according to your network design. If you’re deploying a DMZ, connect the DMZ interface as required. Ensure the management computer is on the same layer-2 network segment as the TZ370’s initial management interface.
• Access the management interface: Use a computer on the same network to connect to the TZ370’s default management IP address. Launch a web browser and begin the initial setup wizard. If necessary, consult the device’s quick-start guide for the exact address and credentials.
• Run the setup wizard: Follow the on-screen prompts to configure basic settings, including administrative credentials, time synchronization, and network interfaces. Assign appropriate IP addresses, gateway information, and initial firewall rules. This step establishes the baseline security posture and connectivity.
• Apply licenses and firmware: Install the required security service licenses and update the firmware to the latest stable release. Regular updates ensure you have current threat signatures and security capabilities. Verify license activation and service status in the dashboard.
• Tune security policies and protections: Create or import security policies, configure IPS rules, enable gateway antivirus, botnet protection, and content filtering. Define application control policies to manage bandwidth and access for critical applications while maintaining security controls.\n
• Configure VPN and remote access: Set up IPsec and/or SSL VPN connections as needed for remote workers or site-to-site connectivity. Define authentication methods, user groups, and access rules to secure remote sessions.
• Test and monitor: Validate connectivity to essential resources, perform a basic traffic test, and review the security analytics and threat dashboards. Confirm alerts and logs are flowing to your centralized management console or logging system, and adjust policies as needed for optimal performance and protection.
• Document and maintain: Save configuration backups, retain a change log, and establish a routine for firmware updates and security policy reviews. Regular audits help sustain a strong security posture as the network evolves.
