WIREGUARD_VPN
Complete WireGuard VPN setup guide. Anonymous, fast, and lightweight. For Windows, Linux, macOS, mobile.
WHAT IS WIREGUARD?
WireGuard is a modern VPN protocol that's extremely lightweight and fast. Unlike OpenVPN, it uses kernel-level networking for performance comparable to direct connections.
IMPORTANT: READ THIS FIRST
Before setting up any VPN, understand that you're trusting your VPN provider with all your traffic. Use reputable providers like Mullvad, hide.me, or ProtonVPN.
For this guide, we recommend: Mullvad VPN (paid, cash by mail possible) or hide.me (free tier available)
STEP 1: CHOOSE A VPN PROVIDER
You need a VPN provider with WireGuard support. Here are the best options:
MULLVAD (RECOMMENDED)
- • No email required
- • Cash payments accepted
- • Sweden jurisdiction
- • €5/month, no trial needed
HIDE.ME
- • Generous free tier
- • Malaysia jurisdiction
- • 10 Gbit/s servers
- • Port forwarding included
SELF-HOSTED
- • Maximum privacy
- • You control everything
- • Requires VPS (€5-10/month)
- • More complex setup
STEP 2: WINDOWS SETUP
2.1 Install WireGuard
-
A.
Download WireGuard from wireguard.com/install
-
B.
Run the installer (Windows Store version recommended or MSI)
-
C.
If asked, create a firewall exception for WireGuard
2.2 Import VPN Configuration
After subscribing to a VPN provider, you'll get config files or credentials:
Option A: Import from File (.conf or .zip)
Click "Import Tunnel(s) from File" and select your provider's config.
Option B: Manual Configuration
- Click "Add Tunnel" → "Add Empty Tunnel"
- Name: "Mullvad Sweden" (or your provider)
- Public Key: Get from your VPN dashboard
- Endpoint: Get from your VPN dashboard (e.g., 185.xxx.xxx.xxx:51820)
- Allowed IPs: 0.0.0.0/0 (all traffic through VPN)
- DNS: Your provider's DNS (Mullvad: 194.242.2.2)
2.3 Activate & Test
-
A.
Click "Activate" on your new tunnel
-
B.
Verify connection: The switch should toggle to "On"
-
C.
Test at
ipleak.netormullvad.net/check
CRITICAL: ENABLE KILL SWITCH
A kill switch blocks all internet if your VPN disconnects. Without this, your real IP leaks instantly.
- WireGuard Kill Switch: Edit Tunnel → Blocking → Block all traffic when tunnel is disconnected
- OS Kill Switch (Windows): Windows Settings → Network & Internet → Advanced network settings → Network reset → Turn on automatically toggle
- Enable BOTH for maximum protection
STEP 3: LINUX SETUP (Debian/Ubuntu)
3.1 Install WireGuard
sudo apt update && sudo apt install wireguard
For Arch: sudo pacman -S wireguard-tools
3.2 Generate Keys
wg genkey | tee privatekey | wg pubkey > publickey
3.3 Create Config
[Interface]
PrivateKey = YOUR_PRIVATE_KEY_HERE
Address = 10.0.0.2/24
DNS = 10.0.0.1
[Peer]
PublicKey = PROVIDER_PUBLIC_KEY
Endpoint = PROVIDER_ENDPOINT:51820
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 25
Get these values from your VPN provider dashboard.
3.4 Start Connection
sudo wg-quick up wg0
To stop: sudo wg-quick down wg0
STEP 4: MACOS SETUP
-
1.
Download WireGuard from the App Store or
brew install --cask wireguard -
2.
Import your config from provider or add manually
-
3.
Enable "Block all traffic when tunnel is disconnected" in Settings
STEP 5: MOBILE SETUP
ANDROID
- Download WireGuard from Play Store
- Import config from QR code (scan from desktop)
- Or create tunnel manually with credentials
- Enable "Always-on VPN" for system-wide
iOS (iPhone)
- Download WireGuard from App Store
- Create manual tunnel or import config
- Add to Home Screen for quick toggle
- Note: iOS has some VPN limitations
STEP 6: DNS LEAK PROTECTION
Even with VPN active, your DNS requests can leak. Use your VPN provider's DNS servers:
MULLVAD DNS
194.242.2.2
194.242.2.2
HIDE.ME DNS
185.222.222.222
185.222.222.222

TROUBLESHOOTING
Connection Fails
- • Check firewall/antivirus isn't blocking
- • Try different port (51820 is default)
- • Verify public key matches exactly
- • Check server status at provider
Slow Speeds
- • Try different server location
- • Switch from UDP to TCP (in advanced settings)
- • Check your base internet speed
- • Disable other VPNs/proxies
PRO TIPS
- • Split Tunneling: Only route gaming/privacy-sensitive traffic through VPN, leave rest direct
- • Multi-hop: Chain VPN servers for extra privacy (slower)
- • Port forwarding: Some providers offer this (useful for self-hosting)
- • Always-on VPN: Enable on mobile for continuous protection
>> FAQ / TROUBLESHOOTING
❓ Which commercial VPN is best for privacy?
Three stand out: Mullvad (anonymous signup with cash, no email needed), ProtonVPN (Swiss, audited, Secure Core), and IVPN (transparent, no telemetry). Avoid "no log" VPNs that don't publish third-party audits (NordVPN, ExpressVPN, Surfshark have had multiple scandals).
❓ Can I use one subscription on multiple devices?
Yes. All major providers allow 5-10 simultaneous connections per account. Mullvad gives 5, Proton gives 10 (paid), IVPN gives 7. Some providers count router connections as 1 device that protects all your other devices.
❓ VPN is slowing my internet — what now?
Try: (1) switch to a closer server — distance = latency; (2) use WireGuard instead of OpenVPN (3-5× faster); (3) try different ports (443 or 53 often bypass throttling); (4) try a different provider. Expect 10-30% speed loss on WireGuard, much more on OpenVPN.
❓ Does the kill switch actually work?
Most providers have it, but quality varies. Always test it: enable kill switch, then disconnect the VPN manually. Your internet should die completely. If it doesn't, switch providers. Application-level kill switches (in the VPN client) are more reliable than OS-level (firewall) ones.
❓ How do I know if I have a DNS leak?
Visit dnsleaktest.com while connected. Click "Extended test" — the servers listed should all be your VPN provider, not your ISP. If your ISP appears, the VPN is leaking DNS — enable "DNS leak protection" in settings or configure DNS manually on the adapter.
❓ Can I use a VPN for streaming (Netflix, etc.)?
Most VPNs actively work to unblock Netflix/Disney+, but streaming services also actively block VPN IPs. It's a cat-and-mouse game. Mullvad and Proton are usually most reliable for streaming. NordVPN/ExpressVPN often work but at higher cost and worse privacy.
❓ Do I need a VPN at home if I "trust" my ISP?
It's about threat model, not trust. Your ISP: logs DNS queries (often required by law), hands them to authorities on request, sells aggregated data. A VPN moves that trust to the VPN provider — pick one with verified no-log audits. For many people, Tor for sensitive browsing + VPN for everything else is a better balance than always-on VPN.
❌ NEED HELP?
VPN providers all have support teams, but community knowledge is often faster.
