How to install SonicWall TZ370W

• Unbox and place the appliance: Position the TZ370W on a stable surface in a central location near your network edge. Ensure adequate ventilation and a clean electrical outlet within reach of all required cables.
• Connect network interfaces: Attach the WAN uplink to the internet modem or service provider device and connect LAN ports to your internal switches or directly to critical devices. Include the built‑in wireless access point if you plan to deploy wireless coverage immediately.
• Power up and access the management portal: Power on the device and access the initial management interface through the default browser URL provided in the product documentation. This is where you begin the configuration wizard.
• Run the setup wizard: Follow the on‑screen steps to configure core network settings, including WAN type (DHCP, static, or PPPoE as applicable), LAN IP addressing, and your wireless SSID/security options. Enable required security services and licensing as you go.
• Configure security services and VPN: Set up intrusion prevention, malware protection, DPI rules, application control, and policy‑driven firewall rules. Create IPsec and SSL VPN profiles for remote access and site‑to‑site connections as needed.
• Enable SD‑WAN and monitoring: If you plan to use SD‑WAN, define path policies and failover rules. Verify traffic flows, set alerting thresholds, and enable centralized logging for ongoing monitoring and auditing.
• Apply updates and licenses: Check for firmware updates and apply any required licenses for threat prevention, SSL VPN, and wireless features. Reboot if prompted and verify that all security services report as active.
• Validate connectivity and security posture: Test internet access from clients, verify VPN connectivity from remote devices, and validate wireless coverage. Review firewall logs and reports to confirm policies are enforcing as intended.
