How to choose, use and configure a VPN in Exe GNU/Linux (My opinion)

Exe GNU/Linux caters to power users who prize minimalism, security and fine-grained control. Under the hood it relies on exe-get (a lightweight, APT-inspired package manager), integrates cleanly with systemd and often runs on desktop stacks like Xfce, i3 or Openbox. It ships with a hardened kernel patchset (“exe-secure”), a bespoke firewall front-end (exe-fw), and places all third-party software under /opt/exe. Given this environment, the ideal VPNs are those offering native Linux CLI tools, open-source or audited clients, and repositories (or .deb packages) you can drop straight into exe-get.

After extensive testing on Exe’s rolling-release channel—and ensuring compatibility with exe-fw and NetworkManager-based GUIs—the standouts are:

  • Mullvad – battle-tested, CLI-first, truly anonymous account model.
  • ProtonVPN – open-source client, strong Linux support, integrated kill-switch.
  • IVPN – privacy-centric, audited codebase, robust obfuscation.
  • NordVPN – polished Linux CLI, lots of servers, built-in threat protection.

Here’s a quick comparison tailored to Exe GNU/Linux:

Service CLI Package Open-Source CLI Kill-Switch P2P Support Jurisdiction
Mullvad mullvad-cli (.deb) Yes Yes (network namespace) Yes Sweden
ProtonVPN protonvpn-cli (.deb) Yes Yes Yes Switzerland
IVPN ivpn-cli (.deb) Partially (wrapper only) Yes Yes Gibraltar
NordVPN nordvpn-linux (.deb) No (closed CLI) Yes Limited Panama

Mullvad – Installation Configuration

Mullvad’s open-source CLI runs flawlessly on Exe. You get a small mullvad binary, plus a systemd unit for auto-reconnection.

1. Add the official Mullvad repo and install:

# wget -qO /usr/share/keyrings/mullvad-archive-keyring.gpg https://keyserver.ubuntu.com/pks/lookup?op=getampsearch=0x3EDBE90A4E8C7722
# echo deb [signed-by=/usr/share/keyrings/mullvad-archive-keyring.gpg] https://repo.mullvad.net/debian stable main gt /etc/apt/sources.list.d/mullvad.list
# exe-get update
# exe-get install mullvad
  

2. Log in using your account number:

 mullvad account login YOUR-ACCOUNT-NUMBER
  

3. Start the service:

# systemctl enable --now mullvad-daemon.service
# mullvad connect  # default to fastest server
  

4. Verify status and firewall integration:

 mullvad status
 exe-fw list  # should show the tun0 interface locked down
  

ProtonVPN – Installation Configuration

ProtonVPN publishes a Debian package and an open-source Python CLI. Perfect for Exe.

1. Install dependencies and the repo key:

# exe-get install openvpn dialog python3-pip
# pip3 install protonvpn-cli
  

2. Initialize:

 sudo protonvpn-cli init
  

Provide your ProtonVPN credentials when prompted.

3. Connect to a server:

 protonvpn-cli c --fastest
  

4. Enable the built-in kill-switch:

 protonvpn-cli ks --on
  

IVPN – Installation Configuration

IVPN’s client is available as a Debian package and integrates with NetworkManager for XFCE/i3 setups.

1. Download amp install:

# wget https://www.ivpn.net/files/linux/ivpn-cli.deb -O /tmp/ivpn-cli.deb
# exe-get install /tmp/ivpn-cli.deb
  

2. Authenticate:

 ivpn login
  

3. Connect with high-security profile:

 ivpn connect --multihop
  

4. Use the built-in firewall locking:

 ivpn firewall enable
  

With these three VPNs configured on Exe GNU/Linux, you’ll enjoy solid privacy, seamless integration with exe-fw and systemd, plus excellent CLI tooling for both minimalism and advanced scripting.
