Introduction

Free firewall is a full-featured professional firewall that protects against the threats of the Internet. Control every program on your computer by permit or deny access to the Internet. Free firewall notifies you when applications want to access the Internet in the background without your knowledge.

Use cases

Monitoring and control

Monitor the Internet access of any program running on your computer. Define rules that control Internet access individually for each program.

Protection against attackers

The software protects you against attackers from the Internet and the local network.

Privacy

When surfing the Internet you leave many traces. Various techniques can be used to track internet users and monitor their activities. The software protects you from tracking and monitoring on the Internet.

Setup

To set up the software on your computer, you must first download the installation file. You can find this on the website: FreeFirewall Download.

Updating the software

The software occasionally receives updates that provide new features or fix bugs.. You can check on the product page of the software whether a newer version is available or when an update appears. For each new program version, the change log is used to determine whether it is downwards compatible with the previous version. Ensure that you are installing only updates that are backward compatible with your installed program version. Each update has its own stability label:

  • Beta: These program versions are still under development and have not been adequately tested. You should only install these program versions on a test device which you do not use productively.
  • Preview: These program versions have not yet been adequately tested. You should only install these program versions on a test device which you do not use productively.
  • Release: These program versions have been adequately tested and can be used on productive systems.
Note : Update the software on all devices simultaneously.

Incompatible updates

If you want to install a newer version of the program, which is not backward compatible with the existing one, you should do this as follows:

  1. Back up all your data from the existing installation to a secure disk.
  2. Note the configuration and settings of the existing installation.
  3. Uninstall the old program version. When uninstalling, select the complete uninstallation.

Applications

After setting up and starting the software, all running programs are displayed in the user interface.

Permissions

You can set permissions for each program individually.

Possible permissions are :

  • Ask for permission : Each time you access the Internet, the software displays an Internet access event that you approve or block.
  • Allow all : Every internet access is automatically approved by the firewall.
  • Deny all : Any Internet access is automatically blocked by the firewall.
  • Apply rules : Each Internet access is automatically decided on the basis of rules for this program. Rules can be created by the user.
Note : As soon as you change the permissions of programs, they are accepted by the program within 10 seconds.

Services

Similar to running programs, background services are also monitored. Individual authorizations can also be assigned for services.

Warning : Services provide important functions in the operating system. An incorrect configuration can cause problems accessing the network and the Internet.

Rules

In addition to allowing or prohibiting everything from two privilege levels, there is a more precise assignment of permissions by rules. Rules consist of an address and a port and an permission.

If a program accesses the network or the Internet, all the rules listed are checked until one matches the destination address. If a matching destination address is found, the respective permissions assigned to the rule are applied and processing ends.
If none of the specified rules match the destination address, the last rule will be applied. The last rule can have the following values:

  • Ask for permission : If no match is found after the above rules have been processed, the software displays an Internet access event that you approve or block.
  • Allow all : If no match was found after completing the above rules, Internet access is automatically approved by the firewall.
  • Deny all : If no match was found after the above rules have been processed, Internet access is automatically blocked by the firewall.
  • Apply selected zone rules : If no match was found after processing the above rules, then rules of the selected zone are checked until a match is found.

Add rules

New rules for a program can be created using the Add-button. A rule consists of the following parameters:

  • IP address or domain name
  • Port, port range or star
  • Rule action

IP address or domain name : IP address can be entered in the form of an IP v4 or IP v6 address. The address may additionally contain a sub-mask in the form of a prefix length.

Examples : IP address or domain name

  • 192.168.2.77
  • 192.168.2.77/18
  • 192.168.2.77/18
  • [2001:0db8:0000:08d3:0000:8a2e:0070:7344]
  • [2001:0db8:0000::7344]
  • [2001:0db8:0000::7344]/64
  • exampledomain.com
  • subdomain.example.com

Port, port range or star : The port parameter of a rule can be specified in many ways. Either as a simple numeric number, as a port range, or as an enumeration of ports separated by a comma. The star parameter is used if the rule is to apply to all ports.

Examples : Port

  • 80
  • 433
  • 80-433
  • 80,433,8080,8443
  • *

Rule action : The rule action determines if the rule applies to a network access that either blocks or allows network access.

Zones

Zones are an extension of the rule concept. Rules provide a fine-grained assignment of permissions to a particular program. Since many programs should have similar permissions, it makes sense not to assign these rules individually to each program, but to create a zone. In this zone all rules are listed. Then the zone can be assigned to one or more programs.

Settings

The software provides you with options and settings to change the behavior of the software.

General settings

Start program with Windows

The program starts automatically each time you start the computer.

Check for updates and notify

The program automatically searches for a more recent version of the program and notifies you of an update.

Prevent hibernate during synchronization

While files are synchronized with the Cloud, hibernation or standby is prevented.

Language selection

Choose your language by clicking on a flag .

Synchronisation

Cloud Assignment Strategy

An allocation strategy specifies the order in which the storage space of the cloud services is been allocated.

  • Optimized for speed : Combination of cloud service for maximum speed
  • Random : Files are uploaded randomly to a cloud service
  • Strong fragmentation : Large files are distributed to as many different cloud stores as possible
  • Available disk space : Cloud services with a largest available storage space will be filled first
  • Linear : Upload are distributed in the same order to the cloud storage services as they are arranged in the list
  • Uniform allocation : All cloud storage services have approximately the same amount of data

Path for the cache

An allocation strategy specifies the order in which the storage space of the cloud services is been allocated.

Compression

Files can be compressed before uploading to the cloud to save storage space and transmission time.

  • No compression : Files are uploaded without compression
  • Fast compression : Files compressed quickly
  • Medium compression : Files are compressed balanced
  • Strong compression : All files are highly compressed before upload

Upload / download bandwidth restriction

Limit the bandwidth available for downloading or uploading the files. Enter a number to enable the restriction.

Proxy in company or home network

If you use a proxy to connect to the Internet, the software allows you to configure the proxy connection. The software supports different proxies:

  • HTTP proxy
  • HTTPS/SSL proxy
  • SOCKS v4 proxy
  • SOCKS v4 type A proxy
  • SOCKS v5 proxy
  • SOCKS v5 type H proxy

You can use the system's proxy configuration to manage the settings for all programs centrally. To do this, choose the entry in the selection menu.

Note : After entering a proxy or changing the proxy configuration, you should restart the software to ensure that all settings are fully applied..
