Security and privacy best practices on Proton VPN
– Kill switch: Ensure it’s active so that traffic is blocked if the VPN drops.
– DNS leakage prevention: Use a trusted DNS resolver and verify no DNS leaks when connected.
– IPv6: Disable IPv6 to prevent leaks if Proton VPN’s IPv6 support isn’t fully integrated with your setup.
– Auto-connect: Configure your Mint session to auto-connect to VPN on boot or login, so you don’t forget.
– Regular updates: Keep Proton VPN client and OpenVPN package up to date to benefit from security patches.
– Firewall rules: Consider basic firewall rules that allow VPN traffic but limit unnecessary inbound access when not connected.
Tips to verify privacy integrity:
– After connecting, run a quick test: visit a site that shows your IP and location to confirm you’re on VPN.
– Do a DNS leak test to ensure DNS requests don’t bypass the VPN tunnel.
– Check that your real IP isn’t visible when you use services that require IP verification e.g., streaming services.
Performance and reliability considerations
– Server proximity: For speed, connect to a server near your actual location.
– Protobuf vs UDP: UDP is typically faster for VPNs. select a UDP server when available.
– System resources: Linux Mint is lightweight, but older hardware may see different performance. monitor CPU and RAM usage if you notice slowdown.
– Concurrent connections: Proton VPN’s tiers determine how many devices you can connect simultaneously. If you’re in a shared environment, plan accordingly.
– DNS latency: If you see slow DNS resolution, consider changing to your provider’s DNS or a faster public DNS like 1.1.1.1 or 9.9.9.9.
Troubleshooting quick hits:
– Connection drops: Try a different server, enable the kill switch, and check for network fluctuations.
– DNS leaks: Recheck DNS settings after connecting and consider forcing a DNS resolver via the CLI or OpenVPN config.
– IP not changing: Ensure you’re not using an alternative route or proxy that bypasses the VPN.
Advanced configuration and tips for power users
– Split tunneling: If Proton VPN supports split tunneling in your chosen path, configure it so only certain apps use VPN while others use direct access.
– Custom routes: For OpenVPN, add manual routing rules to ensure certain traffic stays local.
– Systemd timers vs services: For auto-connect, you can use a systemd timer instead of a service, depending on your preference.
– GUI integration: If you’re more comfortable with a GUI, consider pairing the CLI or OpenVPN with a lightweight network manager plugin for Proton VPN status.
Maintenance and staying up-to-date
– Regular updates: Run sudo apt update and sudo apt upgrade regularly to keep Proton VPN current.
– Log reviews: Check Proton VPN logs or system logs if you encounter connection problems.
