Fort Firewall is in Auto-Learn mode after installation.
You need to change a Filter mode to Block, if not allowed. And review the automatically allowed applications in the Programs window.
This initial behavior is for when you install it on a remote computer, so that the connection is not automatically blocked.
You can check Blocked Connections in the Statistics window.
Or use System Informer program's "Firewall" tab to check blocked connections.
Install the latest Visual C++ x86 redistributable package.

Dark Modeis not supported.
The "Apply the same rules to child processes" option only affects new processes, so you need to restart a program after changing its options.
What is the difference between "Internet Addresses" and "Allowed Internet Addresses" on the "IP Addresses" tab?
- All FW rules apply to "Internet Addresses" only. LAN addresses are allowed immediately by the FW and are not checked by application groups or speed limiter.
For example here you can describe Internet addresses as:
- "Include All" addresses,
- but exclude 127.0.0.0/8, 192.168.0.0/16.
- "Allowed Internet Addresses" may be used for example:
- to block only some addresses:
- "Include All" addresses,
- but exclude facebook.com: "31.13.72.36".
- to allow only some addresses:
- "Exclude All" addresses,
- but include wikipedia.com: "91.198.174.192".
- If address is 127.* or 255.255.255.255 and "Filter Local Addresses" is turned off, then PERMIT
- If "Filter Enabled" is turned off, then PERMIT
- If "Block Traffic" is turned on, then BLOCK
- If address is not from "Internet Addresses" and "Filter Local Network" is turned off, then PERMIT
- If "Block Internet Traffic" is turned on and address is from "Internet Addresses", then BLOCK
- If address is not from "Allowed Internet Addresses", then BLOCK
- If app path is blocked, then BLOCK
- If app has "Block Internet Traffic" and address is from "Internet Addresses", then BLOCK
- If app has Zones and address is rejected or not accepted by Zones, then BLOCK
- If app's Group is disabled, then BLOCK
- BLOCK or PERMIT due to App Group's and “Filter Mode” options
It modifies the selected Service's settings in the registry "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<SERVICE-NAME>":
- changes the "Type" value to "16" (Own Process),
- adds "-s <SERVICE-NAME>" argument to "ImagePath" value,
- stores old "Type" & "ImagePath" values into "_Fort*" values.
For the new values to take effect, you must restart the services that have been changed or restart the computer.
(Some services already run with "-s <SERVICE-NAME>" argument by SvcHost.exe, so it's not necessary to make them explicitly traceable).
The Windows Filtering Platform (WFP) is a set of API and system services to create applications that can filter and modify TCP/IP packets, monitor or filter network connections, and enforce security policies on network traffic.
WFP is configured by installing providers of filter rules: WFP Architecture.
All firewalls (based on WFP) use a filter provider: the default Windows Firewall's provider or a custom one.
For example, WFC and Glasswire use Windows Firewall's default provider.
But SimpleWall and TinyWall use their own provider.
There is a Filter Arbitration mechanism to process multiple providers in WFP.
In addition, firewalls can use the standard WFP filtering mechanism or a custom mechanism using a custom kernel driver - Callout driver.
Therefore, some firewalls use their own drivers for flexible filtering.
For example, Fort Firewall, NetLimiter and Portmaster.
