How to choose, use and configure a VPN in Oracle Linux (Tutorial)

Why Oracle Linux Needs a Tailored VPN Solution

Oracle Linux, being a downstream rebuild of Red Hat Enterprise Linux, employs RPM packages and the yum/dnf ecosystem. Many users are sysadmins and enterprise engineers who expect stability, ease of integration with existing repositories (including ULN and EPEL), and compatibility with SELinux and Kernel Care patches. Typical desktop environments include GNOME on Oracle Linux 8, KDE Plasma spin, or minimal window managers (i3, Xfce) for server consoles.

Because Oracle Linux is used in production and dev-ops contexts, the most suitable VPNs are those offering:

Official RPM packages or YUM/DNF repository to simplify updates.
Systemd service integration and SELinux-friendly profiles.
CLI and GUI support for both headless servers and workstation desktops (GNOME).
Reliable kill-switch and modern protocols (WireGuard®, OpenVPN).

Installation and Configuration Guides

1. NordVPN

NordVPN provides an official YUM/DNF repository and a nordvpn CLI tool that integrates with systemd for the kill switch.

Add the NordVPN repository:

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://repo.nordvpn.com/yum/nordvpn.repo

Import GPG key and install the client:

sudo rpm --import https://repo.nordvpn.com/gpg/nordvpn_public.asc
sudo yum install -y nordvpn

nordvpn login
nordvpn set protocol nordlynx
nordvpn set killswitch on
nordvpn connect

Enable autostart on boot (systemd):

sudo systemctl enable nordvpnd
sudo systemctl start nordvpnd

2. ProtonVPN

ProtonVPN offers an RPM repository and an official CLI called protonvpn-cli which supports WireGuard® and OpenVPN.

Enable the repository and import its key:

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://repo.protonvpn.com/yum/protonvpn-stable.repo
sudo rpm --import https://repo.protonvpn.com/protonvpn_public.gpg

Install the ProtonVPN client:

sudo yum install -y protonvpn protonvpn-cli

Initialize the CLI, login, and connect:

protonvpn-cli login your-email@example.com
protonvpn-cli c --sc

Enable the kill switch and DNS leak protection:

protonvpn-cli ks --enable
protonvpn-cli ns --enable

For GUI users, install the ProtonVPN GNOME client:

sudo yum install -y protonvpn-gui

3. ExpressVPN

ExpressVPN supplies an RPM package. Configure via CLI, or use the native GUI.

Download and install the RPM:

curl -O https://www.expressvpn.works/clients/linux/expressvpn-3.0.0.12062-1.x86_64.rpm
sudo yum install -y expressvpn-3.0.0.12062-1.x86_64.rpm

Activate and connect:

expressvpn activate
expressvpn connect

Enable network lock (kill switch):

expressvpn preferences set network_lock 1

Conclusion

Oracle Linux demands VPNs that integrate smoothly with its RPM/YUM system, SELinux policies, and systemd. NordVPN and ProtonVPN stand out with robust repositories, kill-switch features, and WireGuard® support, while ExpressVPN and Mullvad offer reliable alternatives for both GUI and headless environments. Choose the one that matches your preferred protocol, server footprint, and management workflow.
