IPFire is an open-source Linux distribution with many useful features such as web based GUI, web proxy, intrusion detection, VPN, virus scanner, and many. Visit the official website for more details. It has many add-ons which can be installed with a single click and makes the system administrators life much easier.
Minimum System Requirements:

We’re not finished yet. At first time you log in to IPFire system, you’ll be asked some extra questions.

Enter the “admin” user password for web based administration. Here also, passwords will not be shown(even the ***** characters too).
Here, we reached the important section. pay little more attention. You have to carefully select the Network configuration. Here let me explain you about the network zones of IPFire.
The default network configuration type is Green + Red, which means 2 networks. Typically, your Green network is for your LAN and your Red network is for WAN(Internet).
A maximum of 4 networks is possible – namely Green, Blue, Orange, and Red.
|– External network, connected to the Internet
|– Internal/Private network, connected locally
|– Unprotected/Server network, de-militarized Zone
|– Wireless Network, separate network for wireless clients
You can choose the network type depending upon your environment.
Choose the Network configuration type, and click OK.
Select the network configuration for IPFire. In my case, I go with default network configuration i.e Green and Red. Green Network is connected to my local network, and the Red network is connected with WAN i.e to the router. Click Ok to continue.
Select Drivers and card assignments option, and click Ok.
Choose the interface you want to change ex.Green.
Then, select the a nic for the Green network.
Likewise, choose the interface for Red zone.
After assigning interfaces for both zones click Done to save the changes.
Now, you will be again redirected back to your Network Configuration Wizard.
Click on Address settings to set the IP Address for the network interfaces.
Select Green interface, and click OK.
Enter the IP Address for Green interface.
Then, set IP Address to RED interface. Set your WAN IP address.
After setting up IP addresses click Done to return back your network configuration wizard.
Click on the DNS and Gateway settings tab and set your DNS and Gateway details.
After completing all the above steps, click Done to finish the network configuration.
If you want to set this system as DHCP server for your LAN, check on Enabled button and enter the IP range to serve to your LAN systems. Here, I am not using this server as DHCP. So I leave it as unchecked.
Finally, click OK to complete the setup wizard.
The system will automatically restart now. That’s it. Now the installation part is over.
The network configuration part might be little bit difficult for newbies. But, if you understand the concept, it’s very easy. Read the instructions carefully, and set the values.
After your system is rebooted, access the IPFire administration console by navigating to https://ip-address-of-server:444/ from your client system browser.
Enter username as admin, and password that you created during the installation process.
This is how the IPFire main dashboard looks.
From here, you can configure many services like Intrusion detection, VPN, Web proxy, firewall and so on. Let us see some.
This section will show you the graph details of System, Memory, Network, hardware, and many.Also you can view the reports in daily, weekly, monthly and yearly basis.
This is the important, and interesting section. In this section, we can configure a lot of options such as:
- Web proxy
- URL Filter
- Update accelerator
- DHCP Server
- Connection scheduler
- DNS Forwarding
- MAC address assiging
- And more.
Using this option, we can make this server to act as a Internet proxy server for our LAN. You can set both transparent and non-transparent proxy.
You don’t have to mess up with commands. You can setup squid proxy server with few mouse clicks instantly.
This section is much useful to optimize the Internet connection. In this section, we can block unwanted ads, porn websites, social networking sites, hacking, drugs, audio-video websites and so on.
If you want to block particular domains or websites, just add them one by one in the custom black list section. The domains or websites added in this list will be blocked automatically. Or you can add all the websites in a separate text file and import it to IPFire firewall.
There are other sections such Update accelerator, DHCP server, Connection scheduler etc. Go through to the other sections, and make the changes as per your wish.
In this section, you can configure services such as VPN, Intrusion Detection, Dynamic DNS, and so on.
The firewall section allows to allow/deny the inbound and outbound connection in your network. In this section, you can add the firewall rules whatever you want to implement.
IPFire has a package manager called pakfire which can be used to add extra add-ons. Pakfire allows you to update the IPFire to the most recent version, and also to add any available plugins.
Well, we reached the last section. In this section, all logs such as proxy logs, firewall logs, IDS logs and URL filter logs will be available. Using these logs, we can track users and keep an eye on them what they are doing on Internet.
IPFire is one of the powerful, robust, and free firewall distribution ever I have tested. We can deploy it in just only few hours. The installation and configuration is simple and straight forward. If you still have difficulties, you can get support from IPFire. The IPFire team is also providing commercial support and hardware appliances too.
If anybody using this firewall right now, please let us know about it’s performance in the comment section.
Thanks, and Good Luck.
