How to install SonicWall TZ370W

Setting up the TZ370W is a straightforward process designed to minimize downtime and friction during deployment. Start with a clean, organized network environment and ensure you have administrative access to configure security policies and wireless settings. The installation workflow below outlines the essential steps to bring your TZ370W online, configure core security features, and begin protecting your environment from day one.

• Unpack the TZ370W and verify all included accessories and cables are present. Inspect the unit for any physical damage and connect the device to a dedicated power source and a primary management workstation via a trusted network.
• Connect the WAN and LAN ports according to your network design. If you’re using wireless capabilities, ensure the wireless interface is enabled and positioned to provide optimal coverage while avoiding interference from neighboring networks.
• Access the initial setup interface from a wired computer using the default management IP address or the onboarding wizard provided by SonicWall. Log in with the default administrator credentials and immediately change the password to a strong, unique value.
• Run through the setup wizard to configure the basic network settings, including WAN segmentation, DHCP scopes, and administrative access controls. Define security zones (e.g., LAN, WAN, DMZ) and establish baseline firewall rules that reflect your security policy.
• Configure VPN settings for remote access and site-to-site connections, then enable essential security services such as IPS, gateway antivirus, and content filtering. If your license includes Capture ATP or other advanced defenses, enable and tailor policies accordingly.
• Apply policy-based rules for applications, users, and devices to ensure appropriate access while maintaining robust threat protection. Set up centralized monitoring and alerting to detect anomalies and policy violations in real time.
• Update the firmware to the latest release to ensure you have the newest features, improvements, and security patches. Validate that the device is reporting correctly in your management console and that all connected endpoints can reach intended resources.
• Test connectivity across WAN paths, verify VPN tunnels, and perform basic failover checks if SD-WAN features are configured. Confirm wireless clients can authenticate and roam between access points with stable reliability.
• Document the network configuration, save the baseline configuration, and set up ongoing maintenance plans, including regular firmware checks, security policy reviews, and scheduled backups of the appliance’s configuration.
