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 - <s>KB2533623</s> [KB3063858](https://www.microsoft.com/en-us/download/details.aspx?id=47442) update for Windows 7 was required ### Donate: - [Bitcoin](https://www.blockchain.com/btc/address/1LrRTXPsvHcQWCNZotA9RcwjsGcRghG96c) (BTC) - [Ethereum](https://www.blockchain.com/explorer/addresses/eth/0xe2C84A62eb2a4EF154b19bec0c1c106734B95960) (ETH) - [Yandex Money](https://yoomoney.ru/to/4100115776040583) (RUB) - [Paypal](https://paypal.me/henrypp) (USD) ### GPG Signature: Binaries have GPG signature `simplewall.exe.sig` in application folder. - Public key: [pubkey.asc](https://raw.githubusercontent.com/henrypp/builder/master/pubkey.asc) ([pgpkeys.eu](https://pgpkeys.eu/pks/lookup?op=index&fingerprint=on&search=0x5635B5FD)) - Key ID: 0x5635B5FD - Fingerprint: D985 2361 1524 AB29 BE73 30AC 2881 20A7 5635 B5FD ### Reviews of idiots: [<img src="https://assets.kitploit.com/production/public/readmes/1534/13d308a2e930f71ee6dd9c8424c9af55e141b7c85a23b4f9955c4271c547554d.png" />](https://alternativeto.net/software/simplewall-firewall/about/) Look at them, he does not know about [.gitmodules](https://github.com/henrypp/simplewall/blob/master/.gitmodules) and how to use, lol. PS: Without idiots we are not to be fun, yeah! ### Installation: When install rules, you can choose two modes: - Permanent rules - rules are working until you <a href="#uninstall">disable it manually</a>. - Temporary rules - rules are reset after the next reboot. ### Uninstall: When you uninstall simplewall, all previously configured filters stay alive in system.

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. <details> <summary>Solution: Configure blacklist mode in simplewall:</summary> --- 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. --- </details> #### 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: <details> <summary>Solution 1: Enable NCSI through internal system rule:</summary> --- 1) Open `System rules` tab. 2) Allow `NCSI` rule (enabled by default). --- </details> <details> <summary>Solution 2: Disable NCSI through system registry:</summary> --- 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 ``` --- </details> <details> <summary>Solution 3: Disable NCSI through group policy:</summary> --- 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. --- </details> #### Q: How can I disable Windows Firewall?
