Firewalla's router mode offers enhanced network security and control compared to its gateway mode. This guide will walk you through setting up your Firewalla device in router mode, explaining the process clearly and highlighting important considerations. This mode replaces your existing router's functionality, so ensure you understand the implications before proceeding.

Before You Begin: What You'll Need

Your Firewalla device: Make sure it's updated to the latest firmware.
Internet connection: A working internet connection via cable or fiber.
Existing router (optional but recommended): Keeping your existing router as a secondary device for added protection and troubleshooting is a good idea.
Ethernet cables: To connect your Firewalla, modem, and other devices.
Network knowledge (basic): Familiarity with IP addresses, subnets, and DNS servers will be helpful, although the process is designed to be user-friendly.

Step-by-Step Guide to Setting Firewalla to Router Mode

This guide assumes you are familiar with basic network configurations. If not, consulting online tutorials on networking basics is highly recommended before proceeding.

1. Connect Your Firewalla

First, connect your modem directly to your Firewalla device using an Ethernet cable. If you're keeping your existing router, connect the Firewalla to that router via Ethernet. However, keep in mind this is less secure than a direct modem to Firewalla connection.

2. Access the Firewalla Interface

Connect a computer or mobile device to your Firewalla's Wi-Fi network (or via Ethernet). Open a web browser and navigate to the Firewalla's IP address (usually 192.168.1.1 or similar—check the device's documentation).

3. Configure Router Mode

Within the Firewalla interface, look for the network settings or advanced settings section. You'll find an option to switch to router mode. The exact wording might differ depending on your Firewalla model and firmware version.

Important Note: Carefully read all instructions and warnings within the Firewalla interface before proceeding. Changing to router mode will significantly alter your network configuration.

4. Set Up Your Internet Connection

Once in router mode, you'll need to configure your internet connection. This usually involves providing your ISP's PPPoE username and password or other connection details. These details are typically found on your modem or in your ISP's account information.

5. Configure Wi-Fi Settings (Optional)

If you want your Firewalla to handle Wi-Fi, configure the SSID (network name) and password for both the 2.4GHz and 5GHz bands (if available). Choose strong and unique passwords.

6. Configure DHCP Settings

Set up your DHCP server within the Firewalla interface. This automatically assigns IP addresses to devices on your network. You'll want to specify the IP address range and other settings appropriately. Consider reserving IP addresses for important devices.

7. Test Your Internet Connection

Once everything is configured, test your internet connection on multiple devices to ensure they all have access. Verify that you can access websites and online services.

8. Configure Advanced Settings (Optional)

Once the basic functionality is working, explore Firewalla's advanced features such as port forwarding, VPN configurations, and firewall rules. These can be adjusted to refine the network security and optimize for specific applications.

Troubleshooting Tips

No internet access: Double-check your modem and Firewalla connections. Verify your internet credentials within the Firewalla interface.
Slow internet speeds: Ensure you have the correct settings for QoS (Quality of Service).
Device connectivity issues: Make sure devices are correctly configured with an IP address from Firewalla's DHCP range.
Unexpected behavior: Consult Firewalla's documentation or community forums for assistance.

Maintaining Your Firewalla in Router Mode

Regularly check for firmware updates. Keep your Firewalla's rules updated to adapt to changing threat landscapes. Periodically review your network's logs to identify and resolve any issues or suspicious activity.

By following these steps, you can successfully set up your Firewalla in router mode, gaining enhanced security and control over your network. Remember that security is a continuous process; regular updates and monitoring are essential.
