System Architecture & Workflow Guide
01 Architecture Overview
Rlay eliminates the need for complex modem port forwarding (NAT). It creates a secure outbound tunnel from your localhost to our high-performance relay nodes using Kernel-Level Piping.
02 Connection Workflow
Select Local Port
Enter the port your application is running on (e.g., 25565 for Minecraft, 30120 for FiveM).
Choose Protocol
Select TCP for Minecraft Java, Terraria, or Web Servers.
Select UDP for FiveM, Rust, Palworld, or Project Zomboid. UDP support work in progress
Start Tunnel
Click "Start". The application authenticates with the nearest relay node. If the node is not full, a dedicated pipe is established instantly.
Get Public Address
Share the generated address (e.g., play.rlay.com:11455) with your friends. They
can now connect directly without any client-side installation.
03 Troubleshooting
"ERR:FULL" or "Capacity Reached"
The relay node has reached its maximum concurrent capacity (2000 tunnels). Wait for a few minutes and try again, or switch to a different region if available.
Connection Refused
Ensure your local game server is actually running on the port you specified. Rlay cannot tunnel to a closed port. Check your firewall settings locally.
