+## Installation
+
+```bash
+npm install @push.rocks/smartproxy
+```

 ## Usage

-`@push.rocks/smartproxy` is a versatile package for setting up and handling proxies with various capabilities such as SSL redirection, port proxying, and creating network proxies with complex routing rules. Below is a comprehensive guide on using its features.
-
-### Setting Up a Network Proxy
-
-Create a network proxy to route incoming HTTPS requests to different local servers based on the hostname.
+### Basic Reverse Proxy Setup

 ```typescript
 import { NetworkProxy } from '@push.rocks/smartproxy';

-// Instantiate the NetworkProxy with desired options
-const myNetworkProxy = new NetworkProxy({ port: 443 });
+// Create a reverse proxy listening on port 443
+const proxy = new NetworkProxy({
+  port: 443
+});

-// Define your reverse proxy configurations
+// Define reverse proxy configurations
 const proxyConfigs = [
  {
-    destinationIp: '127.0.0.1',

 ```

-### Port Proxying
-
-You can also set up a port proxy to forward traffic from one port to another, which is useful for dynamic port forwarding scenarios.
-
-```typescript
-import { PortProxy } from '@push.rocks/smartproxy';
-
-// Create a PortProxy to forward traffic from port 5000 to port 3000
-const myPortProxy = new PortProxy(5000, 3000);
-
-// Start the port proxy
-await myPortProxy.start();
-
-// To stop the port proxy, simply call
-await myPortProxy.stop();
-```
-
-### Enabling SSL Redirection
-
-Easily redirect HTTP traffic to HTTPS using the `SslRedirect` class. This is particularly useful when ensuring all traffic uses encryption.
+### HTTP to HTTPS Redirection

 ```typescript
 import { SslRedirect } from '@push.rocks/smartproxy';

-// Instantiate the SslRedirect on port 80 (HTTP)
-const mySslRedirect = new SslRedirect(80);
-
-// Start listening and redirecting to HTTPS
-await mySslRedirect.start();
-
-// To stop the redirection, use
-await mySslRedirect.stop();
+// Create and start HTTP to HTTPS redirect service on port 80
+const redirector = new SslRedirect(80);
+redirector.start();
 ```

-### Advanced Usage
+### TCP Port Forwarding with Domain-based Routing

-The package integrates seamlessly with TypeScript, allowing for advanced use cases, such as implementing custom routing logic, authentication mechanisms, and handling WebSocket connections through the network proxy.
+```typescript
+import { PortProxy } from '@push.rocks/smartproxy';

-For a more advanced setup involving WebSocket proxying and dynamic configuration reloading, refer to the network proxy example provided above. The WebSocket support demonstrates how seamless it is to work with real-time applications.
+// Configure port proxy with domain-based routing
+const portProxy = new PortProxy({
+  fromPort: 443,
+  toPort: 8443,
+  targetIP: 'localhost', // Default target host
+  sniEnabled: true,      // Enable SNI inspection
+  globalPortRanges: [{ from: 443, to: 443 }],
+  defaultAllowedIPs: ['*'], // Allow all IPs by default
+  domainConfigs: [
+    {
+      domains: ['example.com', '*.example.com'], // Glob patterns for matching domains
+      allowedIPs: ['192.168.1.*'],               // Restrict access by IP
+      blockedIPs: ['192.168.1.100'],             // Block specific IPs
+      targetIPs: ['10.0.0.1', '10.0.0.2'],       // Round-robin between multiple targets
+      portRanges: [{ from: 443, to: 443 }]
+    }
+  ],
+  maxConnectionLifetime: 3600000, // 1 hour in milliseconds
+  preserveSourceIP: true
+});

-Remember, when dealing with certificates and private keys for HTTPS configurations, always secure your keys and store them appropriately.
+portProxy.start();
+```

-`@push.rocks/smartproxy` provides a solid foundation for handling high workloads and complex proxying requirements with ease, whether you're implementing SSL redirections, port forwarding, or extensive routing and WebSocket support in your network.
+### IPTables Port Forwarding

-For more information on how to use the features, refer to the in-depth documentation available in the package's repository or the npm package description.
+```typescript
+import { IPTablesProxy } from '@push.rocks/smartproxy';
+
+// Configure IPTables to forward from port 80 to 8080
+const iptables = new IPTablesProxy({
+  fromPort: 80,
+  toPort: 8080,
+  toHost: 'localhost',
+  preserveSourceIP: true,
+  deleteOnExit: true  // Automatically clean up rules on process exit
+});
+
+iptables.start();
+```
+
+### Automatic HTTPS Certificate Management
+
+```typescript
+import { Port80Handler } from '@push.rocks/smartproxy';
+
+// Create an ACME handler for Let's Encrypt
+const acmeHandler = new Port80Handler();
+
+// Add domains to manage certificates for
+acmeHandler.addDomain('example.com');
+acmeHandler.addDomain('api.example.com');
+```
+
