DNS leak protection Nordvpn 사용법 초보자부터 전문가까지 완벽 가이드 2026년 최신

• Route DNS through VPN; don’t rely on the default system DNS.
• Use DNS over TLS/HTTPS if available, or trusted resolvers like 1.1.1.1 or 9.9.9.9 with VPN DNS options.

Split tunneling considerations

• Decide which apps should go through VPN and which can use direct routing.
• For security, start with full-tunnel all traffic through VPN and only enable split tunneling if you have a clear reason.

Automation and startup

• Create a systemd service for your VPN that starts on boot.
• For WireGuard, use wg-quick@; for OpenVPN, openvpn-client@.
• Add a small health check script to restart the service if the tunnel drops.

Firewall rules

• Allow only VPN traffic when the VPN is up block direct internet access if VPN is down.
• Use nftables or ufw to enforce rules: default deny, allow loopback, VPN, and current LAN as needed.

Key management

• Store keys securely; consider a hardware security module HSM or secure key storage.
• Rotate keys periodically and after major security changes.

• If possible, keep two VPN profiles or servers and switch automatically if one goes down.
• Use a monitoring script to ping a stable endpoint and switch tunnels if needed.

Section 6 — Testing and troubleshooting
Common tests

• IP leak test: check whatismyipaddress.com to confirm VPN IP.
• DNS leak test: dnsleaktest.com or equivalents.
• Kill switch test: simulate VPN drop and verify no traffic leaks to the public network.
• Speed test: run Ookla or fast.com to gauge VPN impact.

Common issues and fixes

• DNS leaks after connect: ensure VPN DNS is used and disable system DNS overrides.
• VPN not starting after reboot: check systemd status, enable correct service name, verify config syntax.
• Connection drops: check server status, increase PersistentKeepalive, review firewall rules.
• Slow speeds: try a different server, switch to WireGuard if on OpenVPN, verify MTU settings.

Section 7 — Maintenance and automation
Regular checks

• Update VPN client and server software; apply security patches promptly.
• Review server lists and rotate endpoints if performance declines.
• Verify certificate expiry dates and rotate as needed OpenVPN.

Automation ideas

• A lightweight script to auto-restart VPN on drops and log events.
