OpenVPN CLI Setup Guide.
Astraguard VPN runs perfectly on Linux through the standard OpenVPN client — no proprietary daemon, no closed-source binary. This page walks you through the terminal setup on Ubuntu, Debian, Fedora, Arch, and Raspberry Pi OS, plus privacy hardening with DNS over HTTPS and a firewall kill-switch.
TL;DR — Install
openvpn via your package manager, download the Astraguard .ovpn profile, and run sudo openvpn --config astraguard.ovpn. For always-on, use systemd. For a kill-switch, add a ufw/iptables rule that blocks all traffic unless the VPN tunnel is up.
Why Linux users pick Astraguard
Open protocol, open code, zero logs
No proprietary blobs. OpenVPN is fully open source, battle-tested, and auditable by anyone.
AES-256-GCM cipher
Full AES-256-GCM with RSA-4096 key exchange. Hardware acceleration on x86_64, ARMv8, and RISC-V via OpenSSL.
Works on ARM / Raspberry Pi
Tested on Raspberry Pi OS (32-bit and 64-bit), perfect for a privacy gateway on your home network.
Systemd service / always-on
Drop the .ovpn into /etc/openvpn/client/ and systemctl enable openvpn-client@astraguard for auto-start on every boot.
ufw / iptables kill-switch
Block all non-VPN traffic with two iptables rules so traffic cannot leak if the tunnel drops — we show you exactly how.
Anonymous crypto sign-up
Pay with Bitcoin, Monero, or 148 other crypto options. No name, no bank link.
