Port forwarding is also available through the VS Code extension and the Console.

​
How It Works

When you forward a port, your HTTP service becomes available at: 
https://<instance-uuid>-<port>.thundercompute.net
For example, if your instance UUID is abc123 and you forward port 8080, your service is accessible at: 
https://abc123-8080.thundercompute.net
All traffic is automatically secured with HTTPS and protected against DDoS attacks

​
Forward Ports

​
Interactive Mode

Run the command without arguments to use the interactive interface: 
tnr ports forward
This guides you through selecting an instance and entering the ports you want to forward.

​
Using Flags

Add or remove ports directly with flags: 
# Forward a single port
tnr ports forward <instance_id> --add 8080

# Forward multiple ports
tnr ports forward <instance_id> --add 8080,3000,5000

# Remove a forwarded port
tnr ports forward <instance_id> --remove 8080

# Add and remove in one command
tnr ports forward <instance_id> --add 3000 --remove 8080

​
List Forwarded Ports

See all forwarded ports across your instances: 
tnr ports list

​
Limitations

  • Port 22 is reserved for SSH and cannot be forwarded
  • Valid port range: 1-65535
  • HTTP only: Your service must speak HTTP or gRPC, Other protocols like raw TCP or UDP are not currently supported.

​
Example: Exposing a Web Server

  1. Start a web server on your instance (e.g., on port 8080)
  2. Forward the port: 
    tnr ports forward <instance_id> --add 8080
  3. Access your service at https://<instance-uuid>-8080.thundercompute.net
