Introduction

Once your VPN server is up and running, the next step is connecting your devices securely.
This guide explains how to connect **Windows, macOS, Android, and iOS** to your self-hosted WireGuard or IKEv2 VPN — safely and reliably.

🧩 Part 1: Connecting with WireGuard

• 1. Download the official WireGuard app
  Download WireGuard for your OS:
  • Windows: from wireguard.com or Microsoft Store
  • macOS: from App Store or Homebrew (`brew install wireguard-tools`)
  • Android/iOS: from Google Play or App Store
• 2. Import the configuration file
  Use the `.conf` file you created earlier, or scan the QR code if generated from your server.
  
  Example configuration:
  
  Code:

  	   [Interface]
  	   Address = 10.0.0.2/32
  	   PrivateKey = (ClientPrivateKeyHere)
  	   DNS = 1.1.1.1
  	
  	   [Peer]
  	   PublicKey = (ServerPublicKeyHere)
  	   Endpoint = your.server.ip:51820
  	   AllowedIPs = 0.0.0.0/0
  	   PersistentKeepalive = 25

• 3. Activate the connection
  Click “Activate” (or toggle ON on mobile).
  Once active, you’ll see the WireGuard icon indicating an encrypted tunnel.
• 4. Verify the connection
  Visit ipleak.net or dnsleaktest.com.
  Your IP address should now match your VPN server.

💡 Tip: On Windows, you can enable “Auto-Activate” for faster startup connections.

🔐 Part 2: Connecting with IKEv2/IPSec

• 1. Obtain your connection details
  You’ll need:
  • Server address (e.g. vpn.example.com)
  • Your username and password (from ipsec.secrets)
  • Root CA certificate (ca.crt)
• 2. Import the CA certificate
  This ensures your device trusts the VPN server.
  On most systems, double-click the certificate and choose “Install for all users.”
• 3. Configure the VPN connection
  
  **Windows:**
  • Open Settings → Network & Internet → VPN → Add a VPN connection
  • Provider: Windows (built-in)
  • Connection name: Your choice
  • Server name: vpn.example.com
  • VPN type: IKEv2
  • Type of sign-in: Username and password
  
  
  **macOS:**
  • Open System Settings → VPN → Add Configuration → IKEv2
  • Enter your server address and credentials
  • Import the CA certificate if prompted
  
  
  **iOS:**
  • Settings → General → VPN & Device Management → Add VPN Configuration
  • Type: IKEv2
  • Server: vpn.example.com
  • Remote ID: vpn.example.com
  • Authentication: Username / Password
  
  
  **Android:**
  • Settings → Network → VPN → Add VPN
  • Type: IKEv2/IPSec MSCHAPv2
  • Server: vpn.example.com
  • Enter username and password
  • Import CA certificate if needed
• 4. Connect
  Once saved, select the VPN profile and connect.
  Your status should change to “Connected,” and your public IP should now match your VPN’s address.

💡 Tip: Many modern devices can auto-reconnect to IKEv2 when switching networks — great for mobile users.

🧠 Troubleshooting Tips

• If the VPN doesn’t connect, check your firewall or UDP ports (51820 for WireGuard, 500/4500 for IKEv2).
• Ensure your system clock is correct — expired or mismatched certificates can cause IKEv2 failures.
• If DNS isn’t resolving, specify 1.1.1.1 or 9.9.9.9 inside your config file.
• On mobile, toggle Airplane mode to refresh connections if stuck.

✅ Final Thoughts

Connecting your devices to a self-hosted VPN is straightforward once configured correctly.
WireGuard offers unmatched speed and simplicity, while IKEv2 provides enterprise-grade stability across multiple devices.

Combine your self-hosted VPN with:

• Encrypted DNS (AdGuard DNS, NextDNS)
• 2FA on all logins
• Regular updates and patching

You’ll have a secure, private, and professional-grade setup you fully control.
