You may wish to use a public service for this, such as CloudFlare’s 1.1.1.1 or Google’s 8.8.8.8. Then you’ll be presented with IPFire’s intuitive web interface.īy default IPFire forwards DNS requests to the DNS server on the Red Interface, which is probably your ISP, via your home router. The next thing you’ll see is a login box, into which you should identify yourself as admin using the password you set up earlier. The first thing you’ll see is a nasty security warning because IPFire uses a self-signed certificate. You should be able to connect to IPFire by browsing to. This should be all you need to complete the initial setup of the IPFire instance. (Image credit: Tom's Hardware) Testing, Configuring DNS on IPFire Once we set up our Ubuntu VM to use a static IP, we were able to connect to our IPFire VM. For a physical machine, you can connect to the Green interface IPFire host either by direct cable connection (older 100mbit cards require a crossover cable, gigabit ethernet cards do not) or via a switch. For desktop distros, this is most easily achieved by setting a static IP configuration in Network Manager. So you’ll have to set up Static IP addresses for the VMs you want IPFire to protect here. If you’re using libvirt or Virtualbox, this won’t work since the virtual NAT device has its own DHCP server which will get in the way. Turn this on and use the following settings (or something like them): Start address: 10.0.0.2 Unless you want to mandate that everyone using your private network must use Static IP, the Green interface will need a DHCP server. If you’re running IPFire virtually, then DHCP will use your hypervisor’s NAT network which should work fine. Static IP will require you to set the gateway to that of your home router. The Red interface (in this set up) can be set to receive a IP address via DHCP which offers the easiest set up, but you’ll probably want to configure a static IP later or you’ll be chasing your IPFire instance after a reboot. The Green interface can technically be anything you want, but it’s sensible to use another designated-private IP address such as 10.0.0.1 or (192.168.1.1 if you prefer). In the configuration described above, where we have a secure network ‘underneath’ our home LAN, the Red interface ought to conform to the rest of the LAN with a likely IP address of form 192.168.0.x. IP addresses must be set up for the network devices under IPFire’s control. The idea is that traffic can flow from Green to Red, but not in the other direction. In practice (if you’re not using IPFire on a machine which connects directly to your ISP) these will both connect via your home router ultimately, but your Green network interface will connect (either via crossover cable, wireless or another router switch) to the machines you want IPFire to protect. Typically the Green network will be your private network and the Red network refers to the one connected to the Internet. Use the first option if you need to set up more adapters, and use the second option to assign colors to network hardware. You can use up to four adapters with IPFire, and things get even more colorful if you do that. Make sure the CM4 installation direction is correct before powering up.Setting up Red and Green Networks on IPFireįor a two-adapter setup, we must assign one device the Green network and the other device the Red network. It is recommended not to repeatedly plug and unplug the CM4 module. The board-socket of CM4 is fragile, please align the direction and then press it down. It can also be connected to peripherals and used as a mini-NAS, wireless network bridge, or LTE Internet terminal. The powerful performance of BCM2711 4 core 1.5GHz Cortex-A72 and the rich software support in the Raspberry Pi community make this board a solid foundation for building high-performance gateways, smart routers, and home IoT platforms. It is also compatible with Raspberry OS, Ubuntu Server and other Raspberry Pi systems. After a simple setup, it can be used as a router. Furthermore, there is also a USB2.0 interface that can be connected to mobile hard drives, printers, WIFI modules, LTF modules, etc.Ĭompute Module 4 IoT Router Carrier Board Mini now provides OpenWRT open-source router system. Besides, with a mini size of 55 圆2mm, the board still retains the characteristic GPIO pin header of Raspberry Pi, which makes it applicable for connecting other actuators, sensors, and smart cooling fan. When connecting with a gigabit network card via PCle, it brings Raspberry Pi CM4 two full-speed gigabit network ports and offers better performance, lower CPU usage, and higher stability for a long time work compared with a USB network card. Compute Module 4 IoT Router Carrier Board Mini is an internet expansion board based on the Raspberry Pi Compute Module 4.
