Why you might want a manual VPN setup on Linux

  • Control: You decide which servers you connect to, which encryption you use, and how DNS is handled.
  • Privacy: No vendor app running in the background; you’re not sharing as much telemetry.
  • Performance: In some cases, a manual setup lets you tune MTU, keepalive, and routing for better speeds.
  • Learning: You’ll understand network basics better, which helps in diagnosing issues quickly.

Quick stats to set expectations

  • According to recent independent tests, WireGuard often delivers lower latency and higher throughput than traditional OpenVPN in many scenarios.
  • DNS leak protection is essential; without it, your DNS queries can reveal your browsing activity even when the VPN is up.
  • Proper kill-switch behavior reduces exposure if the VPN drops.

Choosing the right protocol for Total VPN on Linux

OpenVPN

  • Pros: Mature, widely supported, robust in hostile networks.
  • Cons: A bit heavier on resources, slower speeds on some connections.

WireGuard

  • Pros: Lightweight, fast, easier to configure, strong cryptography.
  • Cons: Fewer advanced features than OpenVPN in some edge cases; some corporate policies may require OpenVPN compatibility.

IKEv2/IPsec

  • Pros: Good performance, solid mobile support.
  • Cons: Setup can be more complex; not always available in all distros’ repos.

How to decide

  • If you want speed and simplicity, start with WireGuard.
  • If you’re in a restricted network or need broad compatibility, OpenVPN is a safe bet.
  • For corporate or mobile-heavy environments, IKEv2/IPsec is worth exploring.

Preparation: what's needed before you start

  • A Linux machine with sudo privileges.
  • A VPN provider that supports Linux and provides configuration files or a setup script for WireGuard or OpenVPN.
  • Basic networking basics: an understanding of IP, DNS, MTU, and routing.
  • Optional: a backed-up system, just in case you need to rollback.

Gather your resources

  • VPN provider instructions for Linux official docs
  • The exact configuration files for OpenVPN or WireGuard server config, client keys, and TLS-auth if provided
  • Your preferred DNS resolver 8.8.8.8, 1.1.1.1, or privacy-focused resolvers

D. Routing and DNS considerations

  • Ensure the VPN provider routes all traffic by default redirect-gateway on/off in config.
  • Use DNS servers provided by the VPN or public privacy-respecting DNS e.g., 1.1.1.1, 9.9.9.9 if you don’t rely on VPN-provided DNS.
  • To enforce DNS via VPN, you can push DNS server settings in the .ovpn file or configure resolvconf/systemd-resolved accordingly.

E. Verify the connection

  • Check if the tun interface is up:
    • ip a
    • Look for tun0 or similar with an assigned IP
  • Check the public IP:
    • curl ifconfig.me
  • Confirm DNS is routed through VPN:
    • dig +short example.com @ or use a DNS leak test site
  • Confirm no IPv6 leaks if you’re not using IPv6:
    • curl -6 ifconfig.co

F. Common OpenVPN troubleshooting tips

  • If the tunnel doesn’t come up, check logs:
  • Verify port and protocol match server:
    • In the .ovpn file, look for proto udp/tcp and dev tun
  • Ensure firewall rules allow VPN traffic:
    • sudo ufw allow in on tun0
  • If DNS leaks occur, switch to a DNS server provided by the VPN or configure DNS through resolvectl.
