how to install SonicWall TZ370

• Plan your deployment: Identify the active network segments, determine WAN and LAN requirements, and map out VPN needs for remote users and sites.
• Unbox and connect: Place the TZ370 in a secure environment, connect the power supply, and attach the device to your network per your design (WAN port to ISP modem, LAN ports to internal switches or directly to devices as needed).
• Access the management interface: Use a computer on the same network to navigate to the TZ370’s default IP address and login with the initial credentials provided by the vendor.
• Run the setup wizard: Follow the guided configuration to configure WAN settings, basic firewall rules, and VPN portals. The wizard helps you create trusted networks, security policies, and role-based access as appropriate for your organization.
• Apply security policies: Enable IPS, DPI, SSL decryption, and gateway antivirus as part of a baseline security policy. Fine-tune application controls and content filtering to fit your organization’s compliance and productivity needs.
• Configure VPN and remote access: Set up site-to-site VPN tunnels for branch offices and define SSL/VPN portals for remote workers, with MFA or additional authentication as required by your security policy.
• Enable monitoring and alerts: Turn on logging, alerts, and periodic reports to monitor threat activity, user behavior, and network performance. Schedule routine reviews to adjust rules as your environment evolves.
• Test and optimize: Validate connectivity for critical applications, test failover scenarios if you have multiple WAN links, and adjust security policies to minimize false positives while maintaining robust protection.
