Port Forwarding

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

Start a web server on your instance (e.g., on port 8080)

Forward the port:

tnr ports forward <instance_id> --add 8080

Access your service at https://<instance-uuid>-8080.thundercompute.net
