Dynamic Path MTU Discovery in Cloudflare One Client
Cloudflare One Client now dynamically adjusts MTU size by measuring end-to-end MTU and generating ICMP packet-too-big messages, though it's unclear if this is a novel or overdue feature in VPN clients.
MAIN POINTS
- Cloudflare One Client adjusts local tunnel interface MTU size dynamically.
- It generates ICMP packet-too-big messages near the source.
- The feature's novelty or redundancy compared to other VPN clients is uncertain.
- Feedback on this development is encouraged from users and experts.
TAKEAWAYS
- Dynamic MTU adjustment can improve network efficiency.
- Proximity of ICMP messages to the source may enhance performance.
- Understanding the feature's impact requires user feedback.
- The development highlights ongoing innovation in VPN technology.
