![]() For one thing, it’s its own distro with its own package manager (Pakfire) which can be used directly or behind the scenes to install extra functionality. ![]() But its functionality can be extended far beyond what’s in the box. IPFire has everything you need and more to run an advanced firewall solution. (Image credit: Tom's Hardware) IPFire Add-ons Click update and then you should be able to connect to IPFire’s web interface from anywhere on your LAN.įirewall rules look simple with IPFire, and the IPFire interface looks lovely in the Ubuntu 20.04 daily images. In the Additional settings box, you can choose to log, limit, or rate limit these connections, but we won’t trouble ourselves with that, so just click Add. In the Protocol section choose TCPm select Any in the Standard networks drop down and in the Source section enter 444 in the External port box. In the Destination section select the Firewall option and choose GREEN – 10.0.0.1. Check the Use NAT box below and choose Destination NAT. In the Source section, select the Standard networks option and choose RED. Go to Firewall > Firewall Rules and click the New rule button. This is not something you’d want to do in real life, but it serves to show the procedure for adding rules. We’ll set up a simple rule to allow the Red network to access the web interface on the host. Uncheck the Use ISP-assigned DNS box, and click the Add button at the top. This you can do, by heading to Network > Domain Name System. 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. 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.
