how to install SonicWall TZ370w

• Plan your deployment: Determine the location for the TZ370w with clear access to your internet connection (WAN) and internal network (LAN). Identify devices that will connect through the firewall and note any required VLANs or guest networks.
• Unbox and connect: Power off the unit, connect the WAN port to your internet uplink (broadband modem or service provider gateway), and connect the LAN ports to your internal switch or directly to devices as needed. If wireless is used, configure wireless access points or clients after initialization.
• Power on and access the management interface: Apply power and use a connected computer to access the default management IP address in a supported web browser. Follow the on-screen setup wizard to set a secure administrative password, define network interfaces, and configure basic WAN/LAN addressing.
• Apply licensing and security services: Install or activate required security licenses (intrusion prevention, malware protection, SSL inspection, VPN, etc.). Enable essential services and apply baseline security policies to establish a protected perimeter for your network.
• Configure policies and monitoring: Create firewall rules, NAT settings, and VPN tunnels as needed. Implement threat prevention profiles, application control, and content filtering suited to your environment. Enable cloud management or local monitoring, set up logging and alerts, and ensure firmware is up to date.
• Integrate with cloud management and devices: If you use the SonicWall Cloud Management Portal, connect the TZ370w for centralized policy distribution and monitoring. Register any SonicWall Switch devices and verify that management visibility across your security stack is functioning as intended.
• Test and validate: Run connectivity tests for all critical services (VPN, remote access, internal resources). Validate threat prevention features by generating safe test traffic and confirming that logs reflect policy enforcement. Review dashboards for performance and security posture.
• Establish ongoing maintenance: Schedule firmware updates, review security advisories, and keep licenses current. Set routine backups of configuration and logs, and review system health metrics regularly to ensure optimal operation.
