Step 4: Initial Configuration

After rebooting, configure basic settings:

  • Set the hostname and domain name.

  1. Select Network Type (e.g., RED+GREEN for basic firewall setup).
  2. Assign network interfaces to each zone.
  3. Set the IP address for the GREEN (LAN) network.
  4. Configure DHCP if required.

Step 6: Access the Web Interface

  1. On a computer connected to the GREEN network, open a browser.
  2. Enter the IPFire web interface URL:
    https://[IPFire_LAN_IP]:444
  3. Log in using the admin password set during installation.

Step 7: Configure Firewall Rules

Set up basic firewall rules to allow or block traffic:

  1. Go to Firewall Rules in the web interface.
