Your real-time applications are now faster and more stable, especially on Tunnels with mixed TCP and UDP traffic. +date: 2025-07-15 +--- + +import { Render } from "~/components"; + +Your real-time applications running over [Cloudflare Tunnel](/cloudflare-one/connections/connect-networks/) are now faster and more reliable. We've completely re-architected the way `cloudflared` proxies UDP traffic in order to isolate it from other traffic, ensuring latency-sensitive applications like private DNS are no longer slowed down by heavy TCP traffic (like file transfers) on the same Tunnel. + +This is a foundational improvement to Cloudflare Tunnel, delivered automatically to all customers. There are no settings to configure — your UDP traffic is already flowing faster and more reliably. + +**What’s new:** +- **Faster UDP performance**: We've significantly reduced the latency for establishing new UDP sessions, making applications like private DNS much more responsive. +- **Greater reliability for mixed traffic**: UDP packets are no longer affected by heavy TCP traffic, preventing timeouts and connection drops for your real-time services. + +Learn more about running [TCP or UDP applications](/reference-architecture/architectures/sase/#connecting-applications) and [private networks](/cloudflare-one/connections/connect-networks/private-net/) through [Cloudflare Tunnel](/cloudflare-one/connections/connect-networks/). \ No newline at end of file
