![]() ![]() When we save our configurations, the system will compare new configurations to the old ones and prompt you to overwrite them. We can do this through the main menu, or simply typing in “save-config” at the command prompt. Now that you have your new firewall setup, use the LoginPW option located in the main menu to set a new password for added security.Īnd finally, we will need to save our configurations. By default, however, it will automatically provide you with 20 IP’s for dynamic hosts from the bottom of the IP range. If you have opted in to provide a dynamic IP address on your LAN, you can adjust the settings manually from the DHCP option back at the main menu. Click “Yes” to continue, and then return to the main menu again. Regardless of the option you select, you will still see the screen ask if you want to replace the existing firewall script. Both will install the basic firewall rule settings and use either 2 ports or 3, depending upon your setup. We will need to select the “DMZ3FW” if we are using 3 networking ports, otherwise, just use the FW2 for those who are using 2 networking ports. When coming out of the box, Devil Linux doesn’t have any firewall rules established. Do the same for your 3NIC and configure your eth2. If you would like to provide a network address by means of the DHCP to the local Ethernet network, click ‘Yes’. If you wish to alter those settings, you can do so. Using the standard address is completely fine. This is the networking port in which we will connect to our Ethernet switch, hub and workstation, with the use of a crossover cable. Go through the process and select the module as we did in the first setting even if you are using the same nic. Now we can configure our new firewall Devil Linux. When you get here, the user name should be ‘root’ and the password is blank, so just press enter. When you first start, you will see the Tux Penguin followed by the login prompt. Keep in mind, that if you are having issues booting from the CD drive, try swapping out the CD drive. Now we can boot up our machine once everything is connected and ready to go. If you are purchasing a new card, I recommend getting a 4-port card, as it can use one PCI slot as well as the same kernel module for each of the cards. Hint: You will need to know the module and driver of the card(s) you are using. I made use of an old four port 10/100 Ethernet nic I had laying around that uses ‘tulip’ – a module under the Linux. Your computer will not require a hard drive to operate, but it can provide assistance in saving configurations.įor the network aspect to work properly, I have utilized 3 networking ports on my firewall. This is helpful as it saves the configuration on a separate thumb drive or floppy disk. The Devil Linux is in fact a “live” operating system, meaning that it runs directly from the CD/DVD. If you don’t have one, or know of one, I recommend using PowerISO. Burn the image onto your blank CD/DVD with your selected burning software. Within the zip file, you will see the directory and you should see the “bootcd.iso” file. For those on Apple machines, you can make use of Bunzip2, which is built directly into OS X, however for those using Windows, I suggest using ZipGenius. I highly recommend getting the stable release. For this tutorial, I am using the Linux distro Devil Linux. ![]() My example will be the standard layout of most of your in-home networks: internet access by means of a cable modem box behind the firewall, an internal LAN connecting the workstations, file server, Smart TV’s, and VOIP adapter. There may also be a basic public wireless network separate from the rest of the home network.įirstly, to make the CD. USB Thumb drive, Floppy disk, or Hard Drive.įor those who don’t know much about firewalls or how they work, you will need to know the basic layout of networking designs. ![]()
