A VPN protocol is a set of rules determining how data is encrypted and transmitted between a user's device and a VPN server. It creates a secure, encrypted "tunnel" for online traffic, protecting data from hackers and ISPs by routing it through a remote server.

Top VPN Protocols in 2026

WireGuard: The industry leader in 2026, offering superior speed and lower battery consumption on mobile devices due to its lightweight code.

OpenVPN: A versatile and highly secure open-source protocol widely used for its reliability, though it can be slower than WireGuard.

IKEv2/IPsec: Excellent for mobile users, offering rapid reconnection if the internet connection is temporarily lost.

SSTP: Highly effective at bypassing firewalls, though it is mostly limited to Windows systems.

L2TP/IPsec: An older, secure option that is less commonly used in 2026 due to slower speeds compared to modern alternatives

How to Choose a Protocol

Speed/Streaming/Gaming: Use WireGuard.

Security/Privacy: Use OpenVPN.

Mobile Devices: Use IKEv2

My ACME certificates generated by step-ca don't have a "subject" but they have SANs. Unfortunately, OpenVPN seens to require a subject to work.

Wir setzen uns seit Jahrzehnten intensiv für den Open-Source-Gedanken ein. Aber welche Open-Source-Lösungen gefallen unserem Team eigentlich besonders gut?

Teamlead Consulting Daniel van Soest schätzt z.B. #OpenVPN. Das VPN-Protokoll ist super sicher dank starker Verschlüsselung, sehr flexibel & funktioniert plattformübergreifend.

#Vodafone #DSLite hat mir mal wieder ein Bein gestellt: Konnte von einem Standort eines Freundes meinen heimischen Server (Vodafone-Kabel, richtiger Dual Stack) via #WireGuard nur mit einem Bruchteil der Geschwindigkeit erreichen (ca. 3 Mbit/s). War über einen längeren Zeitraum konstant gleich beschissen. In umgekehrter Richtung war es bei Transfers ähnlich.

Tja, was hat geholfen? MTU auf 1300 setzen (war auf 1420 gesetzt). Immer dasselbe, ey! 😵‍💫 Hatten wir übrigens auch so mit #OpenVPN-Verbindungen auf der Arbeit von Dual-Stack-Lite-Anschlüssen wegen Home-Office. Aber da musste auch erst mal drauf kommen... denke vernünftiges Erreichbarkeit via #IPv6 hätte auch geholfen.

⚠️ Also: Habt ihr Internet via TV-Kabel (mit DS-Lite) und eure Netzverbindung lahmt oder ist unzuverlässig? Versucht es mit einer niedrigen MTU.

Heute ist #DiDay - Die letzten 2 Wochen war ich sehr damit beschäftigt, mein Firmennotebook mit Linux zu betanken. Hier kamen zwangsweise auch Tools wie #Bottles, #OpenVPN, #UCS, #Nextcloud und vieles mehr zum Einsatz. Ich kann Euch sagen: Einfach ist anders, aber es lohnt sich. Als kleines Fallback gibt es nun trotzdem das Backup des alten W11P als VM auf dem #Proxmox. #DIDit #dutgemacht

New blog post: figuring out, and updating upstream bug reports on how to get OpenVPN+DCO (in-kernel encryption/decryption) working on upcoming Ubuntu 26.04 LTS and Fedora 44.

https://www.tuxed.net/fkooman/blog/openvpn-dco.html

Hopefully this can all be fixed before the release, so it works out of the box!

🚀 #OpenVPN 2.7.1 is here!

Running rock-solid on #FreeBSD — and guess what? It works flawlessly on pure INET6-only hosts, no INET needed 💥

Thinking about going #ipv6only ? This is your sign. FreeBSD makes it clean, simple, and powerful.
