What you’ll need gear and credentials
- VPN provider account with OpenVPN/WireGuard support.
- Configuration files or a way to generate keys certificates for OpenVPN or key pairs for WireGuard.
- A Linux machine or VM with admin privileges.
- Optional: a DNS provider you trust or a DNS-over-HTTPS DoH resolver if you want to force DNS through the VPN.
Step-by-step: Manual OpenVPN setup on Linux example
- Prerequisites:
- sudo apt update && sudo apt install openvpn network-manager-openvpn-gnome -y
- Obtain the .ovpn profile from your VPN provider.
- Manual steps:
- Create a dedicated VPN config directory: sudo mkdir -p /etc/openvpn/client && sudo cp your-provider-profile.ovpn /etc/openvpn/client/client.conf
- Convert .ovpn to a usable client config if needed ensure certificates/keys are in the right paths.
- Start the VPN: sudo systemctl start openvpn-client@client
- Enable on boot: sudo systemctl enable openvpn-client@client
- Verify VPN connection: curl ifconfig.me, or check IP on an external site; compare against your real IP.
- DNS considerations:
- Set DNS to a trusted server inside the VPN tunnel. You can push DNS settings from the server or configure /etc/resolv.conf.d/head with the VPN’s DNS IPs.
- Kill switch basics:
- Use iptables to block traffic when VPN is down:
- sudo iptables -A OUTPUT -m state –state NEW -o tun0 -j ACCEPT
- sudo iptables -A OUTPUT ! -o tun0 -m state –state NEW -j DROP
- Use iptables to block traffic when VPN is down:
- Testing:
- IP test, DNS leak test, and IPv6 leakage check disable IPv6 if not used.
Step-by-step: Manual WireGuard setup on Linux example
- Prerequisites:
- sudo apt update && sudo apt install wireguard-tools resolvconf -y
- Generate server and client keys if you’re setting up your own server, or import the configuration from your VPN provider.
- Manual steps:
- Create client configuration: /etc/wireguard/wg0.conf with PrivateKey, Address, DNS; and PublicKey, AllowedIPs, Endpoint, PersistentKeepalive.
- Bring up the tunnel: sudo wg-quick up wg0
- Enable on boot: sudo systemctl enable wg-quick@wg0
- Verify: sudo wg show
- DNS and kill switch:
- Ensure DNS queries go through the VPN by configuring the DNS in the client config or using a local resolver.
- Implement a simple firewall rule to block non-VPN traffic:
- sudo iptables -A OUTPUT -o lo -j ACCEPT
- sudo iptables -A OUTPUT -m conntrack –ctstate ESTABLISHED,RELATED -j ACCEPT
- sudo iptables -A OUTPUT -o wg0 -j ACCEPT
- sudo iptables -A OUTPUT -j DROP
- Testing:
- Check public IP, DNS leaks, and IPv6 status.
Security best practices for Linux VPN usage
- Use a kill switch that blocks all traffic if the VPN drops unexpectedly.
- Disable IPv6 if you don’t plan to use it to avoid leaks through IPv6 routes.
- Use DNS over TLS/HTTPS when possible, or configure your VPN to push DNS through the tunnel.
- Regularly update your system and VPN client software to patch vulnerabilities.
- Verify your certificates and keys are stored securely, with proper permissions.
- Consider multi-factor authentication MFA for your VPN account if supported.
Performance optimization tips
- Choose a nearby VPN server to reduce latency.
- Experiment with MTU settings to avoid fragmentation; start with 1500 and adjust if you see packet loss.
- Prefer UDP-based VPN endpoints for WireGuard or OpenVPN where possible, as UDP typically performs better for real-time traffic.
- Use parallel checks to monitor throughput and adjust server selection accordingly.
- For WireGuard, keep the latest kernel and wireguard-tools to benefit from performance improvements.
Common issues and quick fixes
- VPN won’t connect:
- Check service status, verify credentials, confirm server address and port, and ensure no local firewall blocks the connection.
- DNS leaks detected:
- Force DNS through VPN, disable external DNS resolver, or configure a DNS server provided by the VPN inside the tunnel.
- Slow performance:
- Change servers, switch protocol, optimize MTU, or check for traffic shaping by your ISP.
- IPv6 leaks:
- Disable IPv6 or ensure VPN routes IPv6 through the tunnel if supported.
