WireGuard VPN: Das VPN Protokoll der Zukunft? (2024)

FAQs

How is WireGuard different from other VPN protocols? ›

6 differences between WireGuard and OpenVPN. The biggest notable differences between WireGuard and OpenVPN are speed and security. While WireGuard is generally faster, OpenVPN provides heavier security. The differences between these two protocols are also what make up their defining features.

SUMMARY: OpenVPN offers greater freedom when it comes to encryption and security, but WireGuard is easier to audit and has a smaller attack surface. Both protocols are very secure, but less tech-savvy users may prefer to trust the experts at WireGuard, rather than take matters into their own hands.

The main drawback of the WireGuard protocol is that it was not built for anonymity and privacy. Its privacy is primarily questioned because it requires users to log their data. Instead of assigning a different IP address to the user, it gives the same IP address each time.

WireGuard is a very secure protocol. While it uses shorter cryptographic keys than some previous protocols, it still provides strong encryption. A longer key takes more time to crack, but it would still take millions of years to brute force WireGuard's encryption keys.

What is the most secure VPN protocol? Lightway, IKEv2, L2TP, and OpenVPN are all secure protocols, but the title of the most secure VPN protocol should go to Lightway, which uses wolfSSL, a well-established cryptography library that is FIPS 140-2 validated—which means it has been rigorously vetted by third parties.

WireGuard is originally open source and can be used for free, absolutely. There are many free VPNs that support WireGuard, and it is also included by default in the Linux kernel, so those who are adept at programming can establish these types of encrypted connections simply by typing in the command line.

The default port is 51820 , additional tunnels must use a different port. The GUI will automatically suggest the next highest available port.

What ports do you use for WireGuard? UDP ports 53, 80, 443, 1194, 2049, 2050, 30587, 41893, 48574, 58237.

Should I use IKEv2 or WireGuard? ›

Based on these findings, if you're looking for the fastest secure tunneling protocol, you should go with NordLynx (or WireGuard). The second fastest will be IKEv2, which can confidently hold its own even when connecting to the other side of the world.

WireGuard is easier to set up and configure than OpenVPN because it's slim and light. You don't have that many options to choose from, so it's a lot faster to work with for anyone. OpenVPN, however, comes with a bazillion options.

Why you shouldn't use WireGuard. WireGuard prioritizes speed, ease of use, and network security, but, some might say, at the expense of privacy. WireGuard does lack some standard features and practices many other protocols offer to enhance user privacy protection, such as: Dynamic IP addresses.

With a court order, police can request the ISP to provide subscriber details. VPNs, on the other hand, mask IP addresses by routing traffic through servers. However, if a VPN keeps logs or is compelled to disclose user info, IP addresses can be traced.

A VPN hides your IP address and encrypts your online activity for increased privacy and security. It assigns you a new IP address by connecting you to an encrypted, private VPN server instead of the ones owned by your ISP. This means your activity can't be tracked, stored, or mishandled by third parties.

Compared to IPSec, WireGuard is thought to provide faster performance and more security because of its smaller codebase. On the other hand, IPSec is a well-developed protocol with a wealth of features and compatibility.

WireGuard FAQ

WireGuard is considered by many to be one of the safest, most secure VPN protocol options available today. Simplified design using less code equals fewer bugs and security vulnerabilities, while WireGuard's faster state-of-the-art cryptography employs superior default security settings.

IKEv2 vs WireGuard

WireGuard is a newer option that still has some issues to iron out, but as an open-source protocol, it's more widely available than IKEv2, which has limited compatibility. Both options offer excellent speed.

All VPNs use encryption, but the quality of the encryption depends on which VPN protocol is used. OpenVPN, IKEv2, and L2TP support AES encryption, considered the gold standard, while WireGuard uses ChaCha20, which is also secure. PPTP uses the least secure encryption standard, MPPE.
