### README
simplewall
Definitely for advanced users.
-------
### Description:
Simple tool to configure [Windows Filtering Platform (WFP)](https://docs.microsoft.com/en-us/windows/win32/fwp/windows-filtering-platform-start-page) which can configure network activity on your computer.
The lightweight application is less than a megabyte, and it is compatible with Windows 7 SP1 and higher operating systems.
You can download either the installer or portable version. For correct working you are require administrator rights.
### Nota bene:
Keep in mind, simplewall is not a control UI over Windows Firewall, and does not interact in any level with Windows Firewall. It works
over Windows Filtering Platform (WFP) which is a set of internal API and system services that provide a platform for creating network filtering
applications. Windows Filtering Platform is a development technology and not a firewall itself, but simplewall is the tool that uses this technology.
### Features:
- Simple interface without annoying pop ups
- [Rules editor](https://github.com/henrypp/simplewall#rules-editor) (create your own rules)
- [Internal blocklist](https://crazymax.dev/WindowsSpyBlocker/blocking-rules/simplewall/) (block Windows spy / telemetry)
- Dropped packets information with notification and logging to a file feature (win7+)
- Allowed packets information with logging to a file feature (win8+)
- Windows Subsystem for Linux (WSL) support
- Windows Store support (win8+)
- Windows services support
- Free and open source
- Localization support
- IPv6 support
```
To activate portable mode, create "simplewall.ini" in application folder, or move it from "%APPDATA%\Henry++\simplewall".
```
### System requirements:
- Windows 7, 8, 8.1, 10, 11 64-bit/ARM64
- An SSE2-capable CPU
- KB2533623 [KB3063858](https://www.microsoft.com/en-us/download/details.aspx?id=47442) update for Windows 7 was required

### FAQ:
#### Q: Are internet connections blocked when simplewall is not running?
A: Yes. Installed filters are working even if simplewall is terminated.
#### Q: What apps are blocked in default configuration?
A: By default, simplewall blocks **all** applications. You do not need to create custom rules to block specific applications.
#### Q: Is it safe to use simplewall with Windows Firewall?
A: Yes. You do not need to disable Windows Firewall. These two firewalls work independently.
#### Q: How can i disable blocklist entirely?
A: Open `Settings` -> `Blocklist` and then click the radio buttons labeled `Disable`.
#### Q: Where is blacklist mode?
A: Blacklist was removed many days ago for uselessness. But if you need it, you can still configure it.
Solution: Configure blacklist mode in simplewall:
---
1) Open `Settings` -> `Rules`
2) Uncheck `Block outbound for all` and `Block inbound for all` options.
3) Create user rule (green cross on toolbar) with block action, any direction, `Block connection` name and empty remote and local rule.
4) You can assign this rule for apps whatever you want to block network access.
---
#### Q: Why does my network icon have an exclamation mark?
A: When you are connected to a network, Windows checks for internet connectivity using Active Probing. This feature is named as NCSI (Network Connectivity Status Indicator). You can resolve this problem in one of the following ways:
Solution 1: Enable NCSI through internal system rule:
---
1) Open `System rules` tab.
2) Allow `NCSI` rule (enabled by default).
---
Solution 2: Disable NCSI through system registry:
---
Create `Disable NCSI.reg` and import it into registry.
```reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator]
"NoActiveProbe"=dword:00000001
"DisablePassivePolling"=dword:00000001
```
---
Solution 3: Disable NCSI through group policy:
---
1) Launch the group policy editor (`gpedit.msc` ).
2) Go to `Computer Configuration -> Administrative Templates -> System -> Internet Communication Management -> Internet Communication Settings`.
3) Double-click `Turn off Windows Network Connectivity Status Indicator active tests` and then select Enabled. Click Ok.
4) Open the Command Prompt (Admin) and enter `gpupdate /force` to enforce the changes made to the Group Policies.
