TLS ClientHello Parsing + +When a client connects to the TLS server, it sends a ClientHello message as part of the TLS handshake.

Route Lookup and Registration + +Once extracted, the SNI hostname is used to look up the appropriate tunnel: + +```rust +// During tunnel connection registration +let sni_route = SniRoute { + sni_hostname: "api.example.com".to_string(), + localup_id: "tunnel-api".to_string(), + target_addr: "127.0.0.1:3000".to_string(), +}; + +sni_router.register_route(sni_route)?; + +// During incoming TLS connection +let target = sni_router.lookup("api.example.com")?; +// Now we know this connection should go to tunnel-api +``` + +### 3. Connection Routing + +Once the target tunnel is identified: + +1. The TLS server receives the ClientHello bytes +2. SNI is extracted from ClientHello +3. Route is looked up in the registry +4. A `TlsConnect` message is sent to the tunnel with: + - `stream_id`: Unique stream identifier + - `sni`: The extracted hostname + - `client_hello`: Raw ClientHello bytes + +The tunnel client then: +1. Accepts the TlsConnect message +2. Establishes connection to local TLS service +3. Forwards the ClientHello bytes +4. Proxies all subsequent data bidirectionally + +## Client Usage + +### Configure SNI in Tunnel + +```rust +use localup_client::{ProtocolConfig, TunnelConfig}; + +let config = TunnelConfig { + local_host: "127.0.0.1".to_string(), + protocols: vec![ + ProtocolConfig::Tls { + local_port: 3443, // Local TLS service port + sni_hostname: Some("api.example.com".to_string()), + remote_port: Some(443), + }, + ], + auth_token: "your-token".to_string(), + exit_node: ExitNodeConfig::Auto, + failover: true, + connection_timeout: Duration::from_secs(30), +}; + +let client = TunnelClient::connect(config).await?; +``` + +### Using CLI + +```bash +# Expose local TLS service on port 443 via SNI +localup-relay --tls-addr 0.0.0.0:443 + +# Client connects and registers SNI route +localup --port 3443 --protocol tls --subdomain api.example.com +``` + +## Exit Node Configuration + +### Start Exit Node with SNI Server + +```bash +localup-relay \ + --tls-addr 0.0.0.0:443 \ + --domain example.com +``` + +This makes the TLS server listen on port 443 and routes based on: +- Exact hostname match: `api.example.com` โ†’ tunnel 1 +- Wildcard support planned: `*.api.example.com` โ†’ tunnel 1 + +### Command Line Options + +``` +--tls-addr

+ Enable TLS/SNI routing server on specified address + Format: "0.0.0.0:443" or "localhost:8443" + Optional: if not specified, TLS server is disabled +``` + +## Protocol Integration + +### TunnelMessage Types + +The protocol supports TLS tunneling through these message types: + +```rust +pub enum TunnelMessage { + TlsConnect { + stream_id: u32, + sni: String, + client_hello: Vec, + }, + TlsData { + stream_id: u32, + data: Vec, + }, + TlsClose { + stream_id: u32, + }, +} +``` + +### Protocol Flow + +``` +1. Client connects to relay on port 443 +2. Client sends ClientHello (includes SNI) +3. TlsServer extracts SNI from ClientHello +4. TlsServer looks up route: "api.example.com" โ†’ tunnel-api +5. TlsServer sends TlsConnect{sni, client_hello} to tunnel +6. Client receives TlsConnect and connects to local service +7. Client sends ClientHello bytes to local TLS service +8. Bidirectional TLS data forwarding via TlsData messages +9. Either side initiates TlsClose to end session +``` + +## Implementation Details + +### SNI Extraction Algorithm + +The SNI extraction follows the TLS 1.3 specification (RFC 8446): + +1. Parse record header (type, version, length) +2. Skip handshake header +3. Skip ClientHello fixed fields (version, random, session_id) +4. Skip cipher suites list +5. Skip compression methods list +6.

Example: HTTPS Relay with Configurable Subdomain Policies +//! +//! This example demonstrates how to configure different subdomain selection policies: +//! +//! 1. **Allow Manual Selection** (SimpleCounterDomainProvider): +//! - Users can specify custom subdomains or let the relay auto-generate them +//! - Default behavior - most flexible for development +//! +//! 2. **Restrict to Auto-Generated Only** (RestrictedDomainProvider): +//! - Only auto-generated subdomains are permitted +//! - Useful for multi-tenant deployments with controlled subdomain allocation +//! - Users cannot choose their own subdomains +//! +//! 3. **Custom Policy** (implement DomainProvider trait): +//! - Implement your own validation rules +//! - Example: enforce company-specific naming conventions +//! - Example: require approved subdomains from a whitelist +//! +//!

`localhost:4443`) | +| `transport` | `'quic' \| 'websocket' \| 'h2'` | Transport protocol (default: `'quic'`) | +| `rejectUnauthorized` | `boolean` | Skip TLS verification (default: `false`) | +| `ipAllowlist` | `string[]` | IP addresses allowed to access the tunnel | + +#### Returns: `Listener` + +```typescript +interface Listener extends EventEmitter { + url(): string; // Public URL of the

Events + +- `request` - Emitted for each HTTP request: `{ method, path, status }` +- `close` - Emitted when the tunnel is closed +- `disconnect` - Emitted when disconnected by the relay + +## Environment Variables + +| Variable | Description | +|----------|-------------| +| `LOCALUP_AUTHTOKEN` | Default authentication token | +| `LOCALUP_RELAY` | Default relay address | + +## Examples + +### Basic HTTP Tunnel with QUIC + +```typescript +import localup from '@localup/sdk'; + +const listener = await localup.forward({ + addr: 3000, + authtoken: process.env.LOCALUP_AUTHTOKEN, + transport: 'quic', +}); + +console.log(`Tunnel: ${listener.url()}`); + +listener.on('request', ({ method, path, status }) => { + console.log(`[${method}] ${path} -> ${status}`); +}); +``` + +### Using WebSocket Transport + +If QUIC is not available, use WebSocket: + +```typescript +const listener = await localup.forward({ + addr: 3000, + authtoken: process.env.LOCALUP_AUTHTOKEN, + transport: 'websocket', + relay: 'relay.example.com:443', +}); +``` + +### TCP Tunnel + +```typescript +const listener = await localup.forward({ + addr: 5432, + authtoken: process.env.LOCALUP_AUTHTOKEN, + proto: 'tcp', + transport: 'quic', +}); + +console.log(`PostgreSQL accessible at ${listener.url()}`); +``` + +### With Express + +```typescript +import express from 'express'; +import localup from '@localup/sdk'; + +const app = express(); +app.get('/', (req, res) => res.json({ message: 'Hello!' })); + +const server = app.listen(3000); + +const listener = await localup.forward({ + addr: 3000, + authtoken: process.env.LOCALUP_AUTHTOKEN, + domain: 'my-express-app', + transport: 'quic', +}); + +console.log(`App available at: ${listener.url()}`); +``` + +## Transport Protocols + +The SDK supports three transport protocols: + +| Protocol | Description | Installation | +|----------|-------------|--------------| +| `quic` | Best performance (UDP-based, multiplexed) | `npm install @matrixai/quic` | +| `websocket` | Good compatibility, works through firewalls | Built-in | +| `h2` | HTTP/2 based, maximum compatibility | Built-in | + +### QUIC Transport + +QUIC provides the best performance but requires native bindings: + +```bash +npm install @matrixai/quic +``` + +```typescript +// Check if QUIC is available +import { isQuicAvailable, getQuicUnavailableReason } from '@localup/sdk'; + +if (await isQuicAvailable()) { + console.log('QUIC transport available!'); +} else { + console.log('QUIC not available:', getQuicUnavailableReason()); + console.log('Falling back to WebSocket...'); +} +``` + +Note: `@matrixai/quic` uses Cloudflare's quiche library and requires native compilation. It may not work on all platforms. + +## Development + +```bash +# Install dependencies +bun install + +# For QUIC support +bun add @matrixai/quic + +# Run tests +bun test + +# Build +bun run build + +# Run examples +bun run examples/basic.ts +``` + +## Testing Against a Relay + +To test the SDK against a real LocalUp relay: + +### 1. Start a local HTTP server (the app to expose) + +```bash +python3 -m http.server 8080 +``` + +### 2. Generate a JWT token + +```bash +cargo run -p localup-cli -- generate-token \ + --secret "test-secret-key" \ + --localup-id "test-sdk" +``` + +### 3. Run the test script + +```bash +# With QUIC (requires @matrixai/quic) +LOCALUP_AUTHTOKEN="" \ +LOCALUP_RELAY="tunnel.kfs.es:4443" \ +LOCALUP_TRANSPORT="quic" \ +bun run examples/test-against-relay.ts + +# With WebSocket (no extra dependencies) +LOCALUP_AUTHTOKEN="" \ +LOCALUP_RELAY="localhost:4443" \ +LOCALUP_TRANSPORT="websocket" \ +bun run examples/test-against-relay.ts +``` + +## Protocol
