Build `tunnel.dll` by running `./build.bat` in this folder. The first time you run it, it will invoke `..\build.bat` simply for downloading dependencies. After, you should have `amd64/tunnel.dll`, `x86/tunnel.dll`, and `arm64/tunnel.dll`. In addition, `tunnel.dll` requires `wireguard.dll`, which can be downloaded from [the wireguard-nt download server](https://download.wireguard.com/wireguard-nt/). The basic setup to use `tunnel.dll` is: ##### 1. Install a service with these parameters: - Service Name: "SomeServiceName" - Display Name: "Some Service Name" - Service Type: SERVICE_WIN32_OWN_PROCESS - Start Type: StartAutomatic - Error Control: ErrorNormal, - Dependencies: [ "Nsi" ] - Sid Type: SERVICE_SID_TYPE_UNRESTRICTED - Executable: "C:\path\to\example\vpnclient.exe /service configfile.conf" +```text +Service Name: "WireGuardTunnel$SomeTunnelName" +Display Name: "Some Service Name" +Service Type: SERVICE_WIN32_OWN_PROCESS +Start Type: StartAutomatic +Error Control: ErrorNormal, +Dependencies: [ "Nsi", "TcpIp" ] +Sid Type: SERVICE_SID_TYPE_UNRESTRICTED +Executable: "C:\path\to\example\vpnclient.exe /service configfile.conf" +``` Some of these may have to be changed with `ChangeServiceConfig2` after the initial call to `CreateService` The `SERVICE_SID_TYPE_UNRESTRICTED` parameter @@ -21,22 +23,19 @@ is absolutely essential; do not forget it. ##### 2.
