# Windows Client Setup
|
|
|
|
This guide will help you set up your Windows device to connect to your Algo VPN server.
|
|
|
|
## Supported Versions
|
|
|
|
- Windows 10 (all editions)
|
|
- Windows 11 (all editions)
|
|
- Windows Server 2016 and later
|
|
|
|
## WireGuard Setup (Recommended)
|
|
|
|
WireGuard is the recommended VPN protocol for Windows clients due to its simplicity and performance.
|
|
|
|
### Installation
|
|
|
|
1. Download and install the official [WireGuard client for Windows](https://www.wireguard.com/install/)
|
|
2. Locate your configuration file: `configs/<server-ip>/wireguard/<username>.conf`
|
|
3. In the WireGuard application, click "Import tunnel(s) from file"
|
|
4. Select your `.conf` file and import it
|
|
5. Click "Activate" to connect to your VPN
|
|
|
|
### Alternative Import Methods
|
|
|
|
- **QR Code**: If you have access to the QR code (`wireguard/<username>.png`), you can scan it using a mobile device first, then export the configuration
|
|
- **Manual Entry**: You can create a new empty tunnel and paste the contents of your `.conf` file
|
|
|
|
## IPsec/IKEv2 Setup (Legacy)
|
|
|
|
While Algo supports IPsec/IKEv2, it requires PowerShell scripts for Windows setup. WireGuard is strongly recommended instead.
|
|
|
|
If you must use IPsec:
|
|
1. Locate the PowerShell setup script in your configs directory
|
|
2. Run PowerShell as Administrator
|
|
3. Execute the setup script
|
|
4. The VPN connection will appear in Settings → Network & Internet → VPN
|
|
|
|
## Troubleshooting
|
|
|
|
### "The parameter is incorrect" Error
|
|
|
|
This is a common error that occurs when trying to connect. See the [troubleshooting guide](troubleshooting.md#windows-the-parameter-is-incorrect-error-when-connecting) for the solution.
|
|
|
|
### Connection Issues
|
|
|
|
1. **Check Windows Firewall**: Ensure Windows Firewall isn't blocking the VPN connection
|
|
2. **Verify Server Address**: Make sure the server IP/domain in your configuration is correct
|
|
3. **Check Date/Time**: Ensure your system date and time are correct
|
|
4. **Disable Other VPNs**: Disconnect from any other VPN services before connecting
|
|
|
|
### WireGuard Specific Issues
|
|
|
|
- **DNS Not Working**: Check if "Block untunneled traffic (kill-switch)" is enabled in tunnel settings
|
|
- **Slow Performance**: Try reducing the MTU in the tunnel configuration (default is 1420)
|
|
- **Can't Import Config**: Ensure the configuration file has a `.conf` extension
|
|
|
|
### Performance Optimization
|
|
|
|
1. **Use WireGuard**: It's significantly faster than IPsec on Windows
|
|
2. **Close Unnecessary Apps**: Some antivirus or firewall software can slow down VPN connections
|
|
3. **Check Network Adapter**: Update your network adapter drivers to the latest version
|
|
|
|
## Advanced Configuration
|
|
|
|
### Split Tunneling
|
|
|
|
To exclude certain traffic from the VPN:
|
|
1. Edit your WireGuard configuration file
|
|
2. Modify the `AllowedIPs` line to exclude specific networks
|
|
3. For example, to exclude local network: Remove `0.0.0.0/0` and add specific routes
|
|
|
|
### Automatic Connection
|
|
|
|
To connect automatically:
|
|
1. Open WireGuard
|
|
2. Select your tunnel
|
|
3. Edit → Uncheck "On-demand activation"
|
|
4. Windows will maintain the connection automatically
|
|
|
|
### Multiple Servers
|
|
|
|
You can import multiple `.conf` files for different Algo servers. Give each a descriptive name to distinguish them.
|
|
|
|
## Security Notes
|
|
|
|
- Keep your configuration files secure - they contain your private keys
|
|
- Don't share your configuration with others
|
|
- Each user should have their own unique configuration
|
|
- Regularly update your WireGuard client for security patches
|
|
