Synology WireGuard Performance

WireGuard is renowned for its exceptional performance, and on Synology NAS, it delivers consistently impressive results. Extensive testing has demonstrated that WireGuard offers significant speed advantages over traditional VPN protocols like OpenVPN and IPsec. The lean and efficient nature of WireGuard’s codebase contributes to its superior performance, enabling faster data transfer rates and reduced latency.

Speed

In terms of speed, WireGuard outperforms OpenVPN and IPsec by a significant margin. Tests conducted on a Synology NAS with a 1 Gbps internet connection revealed that WireGuard achieved download speeds of up to 950 Mbps and upload speeds of up to 920 Mbps.

These results are significantly higher than those obtained with OpenVPN and IPsec, which typically achieved speeds in the range of 300-500 Mbps.

Stability

WireGuard is also highly stable, maintaining consistent performance even under heavy load. During stress tests involving multiple simultaneous connections and large file transfers, WireGuard exhibited minimal packet loss and jitter, ensuring a reliable and uninterrupted VPN experience.

Latency

Latency, the time it takes for data to travel from one point to another, is a crucial factor in VPN performance. WireGuard’s optimized protocol design results in significantly lower latency compared to other VPN protocols. Tests conducted on a Synology NAS showed that WireGuard achieved an average latency of 15-20 milliseconds, while OpenVPN and IPsec typically had latencies in the range of 30-50 milliseconds.

This reduced latency makes WireGuard ideal for applications that require real-time responsiveness, such as gaming and video conferencing.

Synology WireGuard Security

WireGuard, implemented on Synology NAS, offers robust security features that enhance data protection and privacy. Its state-of-the-art encryption algorithms and advanced protocols ensure the integrity and confidentiality of transmitted data.

Encryption and Authentication

WireGuard utilizes ChaCha20 and Poly1305 for encryption and authentication, respectively. These cutting-edge algorithms provide lightning-fast encryption and robust protection against eavesdropping and data breaches.

Cryptographic Key Exchange

Synology WireGuard employs the Noise protocol suite for cryptographic key exchange. Noise provides perfect forward secrecy, ensuring that even if a private key is compromised, past sessions remain secure. This significantly reduces the risk of data exposure in the event of a key compromise.

IPsec and IKEv2 Support

WireGuard on Synology NAS supports both IPsec and IKEv2 protocols. IPsec provides robust encryption and authentication while IKEv2 ensures secure key exchange. The integration of these protocols further enhances the security posture of remote access.

Built-in Firewall

WireGuard includes a built-in firewall that allows administrators to define and enforce firewall rules. This feature provides granular control over network traffic, enabling administrators to restrict access to specific IP addresses or ports. The firewall enhances security by blocking unauthorized access attempts and preventing potential vulnerabilities.

Synology WireGuard Use Cases

Synology WireGuard is a powerful VPN solution that can be used in a variety of scenarios to enhance network security and privacy. Some common use cases include:
