What is the issue you’re encountering

We have implemented WARP-to-WARP connectivity using Cloudflare Tunnel, and both ping and file transfers via the Cloudflared interface IP are functional. However, we observed that file transfer speeds are below 1 Mbps through the interface IP, whereas using the public IP achieves speeds of nearly 500 Mbps. Based on our research, this seems related to MTU adjustments, which may not be handled automatically. Could you provide guidance or recommend a solution to optimize the transfer speed for WARP-to-WARP communication?

May I ask if you’ve tested with different packet size? Was the result the same?

Your local network interface doesn’t have any MTU pre-defined, as it knows to be on e.g. dedicated servers with DHCP or static IPs, especially those delivered as Cloud instances/VPS?

Alongside Warp-to-Warp, may I ask if there is some firewall running as well?
