1. Before You Begin

What You’ll Need

  • Palo Alto firewall appliance (e.g., PA-220, PA-800 series)
  • Ethernet cables (for management and data ports)
  • Management PC with:
    • Modern web browser (Chrome or Firefox recommended)
    • Terminal emulator (PuTTY, Tera Term, etc.)
  • Valid support license (required for software updates and threat prevention)

Default Credentials

  • Web GUI: admin / admin
  • CLI: admin / admin (or check device sticker for specifics)

2. Physical Installation

A. Hardware Connections

  • Management Port (MGT):
    Connect your management PC directly to the dedicated MGT port.
    Default IP address: 192.168.1.1/24
  • Network Interfaces:
    • ethernet1/1: WAN (connect to your ISP modem)
    • ethernet1/2: LAN (connect to your internal switch or network)

B. Power On

  • Connect power and wait for system LEDs to stabilize (typically 5–10 minutes).

WatchGuard Firebox – First-Time Setup Guide

This step-by-step guide walks you through setting up your WatchGuard Firebox for the first time, from physical connections to securing your configuration.

What You’ll Need

  • WatchGuard Firebox appliance
  • Ethernet cables
  • Computer with a web browser
  • (Optional) USB drive for backup

Step 1: Physical Connections

  1. Connect to the Firebox
    • Plug your computer into the Trusted (LAN) port (default IP: 10.0.1.1).
    • Connect the External (WAN) port to your modem or ISP device.
  2. Power On
    • Wait 2–5 minutes for the device to fully boot (LEDs will stabilize).

Step 2: Access the Web UI

  1. Configure Your Computer’s Network
    • Static IP (if DHCP is not enabled): IP Address: 10.0.1.100 Subnet Mask: 255.255.255.0 Gateway: 10.0.1.1
    • OR use DHCP if available.
  2. Open the Web Interface
    • In a browser, go to: https://10.0.1.1:8080
    • Default Credentials: Username: admin Password: readwrite

Step 3: Initial Configuration

  1. Run the Setup Wizard(recommended)
    • Change the admin password (System > Administration).
    • Set the hostname and time zone.
  2. Configure Interfaces
    • External (WAN): DHCP or static IP (provided by ISP).
    • Trusted (LAN): Keep 10.0.1.1/24 or customize.
  3. Enable Additional Features (Optional)
    • Firewall Policies: Ensure outbound traffic is allowed (default policy exists).
    • VPN: Configure SSL or IPSec if required.

Step 4: Save & Backup

  1. Save Configuration
    • Navigate to: System > Configuration File > Save.
  2. Create a USB Backup(recommended)
    • Format USB drive as FAT32.
    • Save the config file as WG-Config.xml and insert it into the Firebox.

Troubleshooting

Can’t Access Web UI?

  • Ensure PC is on the same subnet (10.0.1.x).
  • Try a different browser (Chrome/Firefox recommended).
  • Reset the Firebox (hold reset button for 30 seconds).

No Internet via WAN?

  • Verify ISP settings (PPPoE credentials or static IP).
  • Test with a direct modem connection.

Next Steps

  • Update Firmware: System > Software > Check for Updates.
  • Enable Logging: Configure WatchGuard Dimension or Cloud Logging.
