Advanced Configuration

Understanding the Config File

[Interface]
PrivateKey = your-private-key-here# Your device's private key (keep secret!)
Address = 44.190.40.10/24# Your IP address in the VPN network
DNS = 1.1.1.1, 1.0.0.1# DNS servers to use
[Peer]
PublicKey = server-public-key-here# Server's public key
Endpoint = 203.0.113.1:51820# Update with PoP node's IP
AllowedIPs = 0.0.0.0/0# Which traffic to route through VPN
PersistentKeepalive = 25# Keep connection alive (NAT traversal)

Common Configuration Options

Setting Description Example
AllowedIPs Traffic to route through VPN 0.0.0.0/0 (all traffic)
44.0.0.0/9, 44.129.0.0/10 (44net only)
DNS DNS servers to use 1.1.1.1, 8.8.8.8
PersistentKeepalive Keep connection alive (seconds) 25 (recommended)
MTU Maximum packet size 1420 (default)

Split Tunneling

Route only specific traffic through the VPN:

AllowedIPs = 44.0.0.0/9, 44.128.0.0/10# Route only 44.0.0.0/9 & 44.128.0.0/10 through VPN
AllowedIPs = 0.0.0.0/0# Route everything

Troubleshooting Commands

Linux:

# Check interface status
sudo wg show

# View logs
journalctl -u wg-quick@wg0 -f

# Test connectivity (Example, use your IP)
ping 44.190.40.1

# Check routing
ip route show

Windows:

# Command Prompt (Example, use your IP)
ping 44.190.40.1
ipconfig /all
route print

Security Best Practices

Important Security Notes:
  • Never share your private key
  • Use strong, unique keys for each device
