How to install WatchGuard Firebox T25

Step 1 — Plan and position: Choose a secure, well-ventilated location with access to power and your network cabling. Determine your WAN connection (ISP modem or gateway) and identify the primary and secondary LAN segments you will protect. If you’re using the optional Wi‑Fi module, decide where to place it to maximize coverage while minimizing interference.

Step 2 — Connect the hardware: Connect the Internet/WAN source to the Firebox T25’s primary WAN port. Attach your internal network to the LAN ports or to a switch that connects to your user devices, servers, and printers. If you’ve added the Wi‑Fi module, install it according to the product’s instructions and ensure antennae are securely fastened.

Step 3 — Power up and access the management interface: Power on the device and locate its management address via the default network scope or by using WatchGuard’s discovery tools. Log in to the WebUI or use WatchGuard Cloud for centralized management. Update the firmware to the latest release to ensure you have the newest protections and performance optimizations.

Step 4 — Define security policies: Create firewall rules that reflect your security posture—allow essential business traffic while blocking risky services. Enable IPS, anti-malware, and URL filtering, and configure DNSWatch to block known malware hosts. Implement authentication and access rules for administrators and users, and set up device-based policies as needed.

Step 5 — Configure VPN and remote access: Set up the Branch Office VPN tunnels or secure remote access for teleworkers. Choose the appropriate VPN type (IKEv2/IPSec, SSL VPN, etc.) and apply central authentication to ensure only authorized users and devices can connect. Validate connectivity from remote locations to confirm policy enforcement across the network.

Step 6 — enable optional Wi‑Fi and guest access: If you installed the Wi‑Fi module, configure SSIDs, security (prefer WPA3 where available), guest networks, and bandwidth controls. Apply separate policies for guest traffic to isolate it from your corporate network and protect sensitive resources.

Step 7 — Monitor, test, and maintain: Use the dashboards to verify traffic flows, VPN status, and threat activity. Schedule automatic firmware updates, enable security alerts, and routinely review security reports to adjust policies as your environment evolves.
