How to Install SonicWall TZ370

• Plan and prepare: Before powering up the device, outline your network topology, IP addressing plan, and security policies. Decide where the TZ370 will sit in your network—ideally in a secure, ventilated area with access to your management workstation and Internet service provider (ISP) connection.
• Connect hardware and power: Connect the WAN/Internet uplink to the appropriate port and wire LAN devices to the local network ports or switch. Ensure the power supply is securely connected and the unit has adequate ventilation to prevent overheating during prolonged operation.
• Initial access and authentication: Power on the TZ370 and access the management interface using the default IP address listed in the product documentation. Create a strong administrator password and configure role-based access as needed to limit management privileges to authorized personnel.
• Configure basic network settings: Set up WAN interfaces (static, DHCP, or PPPoE as required), define the LAN subnet, and configure DHCP if the TZ370 will serve as a DHCP server for clients. Specify DNS servers and verify Internet connectivity from the management console.
• Apply security policies and licenses: Import or configure security policies for firewall rules, VPN, IPS/IDS, and content filtering. Install or activate required security subscriptions and license keys to enable advanced threat prevention, SSL inspection, and other services.
• Update firmware and perform baseline checks: Check for the latest firmware version and apply updates. Reboot if prompted and validate that all security services are online. Run basic connectivity tests and verify that protected traffic is being inspected and logged as configured.
• Configure VPN and remote access: Create VPN gateways or server profiles for remote users and branch offices, test connections from remote devices, and ensure that VPN traffic adheres to your security policies and logging requirements.
• Establish monitoring and backup: Set up logging/monitoring alerts, configure automatic backups of configuration settings, and schedule regular reviews of security reports to maintain ongoing protection and compliance.
