This document explains how WireGuard VPN is deployed, accessed, and managed when installed as a One-Click App on FlyWP.
What is WireGuard VPN
WireGuard is a modern, high-performance VPN protocol designed to be simple, fast, and secure. It uses state-of-the-art cryptography and has a minimal attack surface compared to traditional VPN solutions.
FlyWP provides WireGuard as a one-click VPN server with a web-based admin UI, eliminating manual key generation and configuration.
Deployment Overview
When you deploy WireGuard from:
Create Site → Deploy One Click App → WireGuard VPN
FlyWP automatically:
- Installs and configures WireGuard
- Sets up the web-based admin UI
- Assigns a FlyWP subdomain or custom domain
- Configures firewall and networking rules
- Enables SSL for the admin UI
No manual WireGuard or CLI setup is required.
Default Access URLs
After deployment, two components are available:
- WireGuard Admin UI
https://<your-domain>/ - WireGuard VPN Service
Runs on the WireGuard UDP port (configured automatically)
The Admin UI is used to manage peers and download client configurations.
Authentication & Login
The WireGuard Admin UI is protected by credentials generated during deployment.
- Login details are available in the FlyWP dashboard under the site details
Store these credentials securely. Anyone with access can generate VPN clients.
Admin UI Capabilities
From the WireGuard Admin UI you can:
- Create and manage VPN peers (clients)
- Download client configuration files
- Generate QR codes for mobile devices
- Enable or disable peers
- View connected clients
No manual key handling is required.
Client Setup
WireGuard clients are available for:
- Windows
- macOS
- Linux
- iOS
- Android
Steps
- Create a peer in the Admin UI
- Download the configuration file or QR code
- Import it into the WireGuard client
- Activate the tunnel
Once connected, traffic is securely routed through the VPN.
Environment & Configuration
Most WireGuard settings are managed internally by the Admin UI.
FlyWP handles:
- Network interface configuration
- IP routing
- Firewall rules
- Service restarts
Advanced customization beyond the Admin UI is not recommended unless you understand WireGuard networking deeply.
SSL & Security
- Admin UI is protected by HTTPS
- VPN traffic is encrypted using WireGuard cryptography
- Keys are generated per peer
Security Best Practices
- Use strong admin credentials
- Disable unused peers
- Rotate peers if a device is lost
- Restrict Admin UI access via firewall or IP allowlist
Managing WireGuard from FlyWP
From the FlyWP dashboard:
- Manage → Restart or redeploy the VPN service
- Logs → View service logs
- NGINX Config → Modify admin UI routing (advanced use only)
Avoid manual changes outside FlyWP unless necessary.
Troubleshooting
Client Cannot Connect
- Verify the tunnel is active
- Check server is running
- Confirm firewall allows WireGuard UDP port
Admin UI Not Accessible
- Ensure the domain is correct
- Check SSL status
- Restart the service from FlyWP
No Internet Through VPN
- Check client routing settings
- Recreate the peer configuration
When to Use WireGuard on FlyWP
WireGuard One-Click App is ideal for:
- Secure remote server access
- Private browsing over untrusted networks
- Team VPN access
- Lightweight site-to-server tunnels
Not intended for complex enterprise mesh VPNs.
Summary
FlyWP’s WireGuard VPN One-Click App provides:
- Instant VPN server deployment
- Simple web-based management
