+
+- Added socket.end() after uncorking the alert packet in ClientHello handling to force connection closure.
+- Prevents duplicate data events and ensures the warning alert is processed by clients like Chrome.
+
+## 2025-03-17 - 4.2.1 - fix(core)
+No uncommitted changes detected in the project.
+
+
+## 2025-03-17 - 4.2.0 - feat(tlsalert)

+- Enhance TLS alert handling for better browser compatibility and error management
+
+## 2025-03-17 - 4.1.16 - fix(tls)
+Improve TLS alert handling in connection handler: use the new TlsAlert class to send proper unrecognized_name alerts when a ClientHello is missing SNI and wait for a retry on the same connection before closing. Also, add alertFallbackTimeout tracking to connection records for better timeout management.
+
+- Replaced hardcoded alert buffers in ConnectionHandler with calls to the TlsAlert class.
+- Removed old warnings and implemented a mechanism to remove existing 'data' listeners and await a new ClientHello.

+- Switched the alert payload from serverNameUnknownAlertData to a new certificateExpiredAlert buffer
+- Now sends a fatal certificate_expired alert (code 47) instead of a warning unrecognized_name alert
+- Improves TLS error reporting and encourages immediate disconnection when a ClientHello lacks SNI and session tickets are disallowed
+
+## 2025-03-17 - 4.1.11 - fix(connectionhandler)
+Increase delay before cleaning up connections when session resumption is blocked due to missing SNI, allowing more natural socket termination.
+
+- Changed cleanup delay in ts/classes.pp.connectionhandler.ts from 300ms to 1000ms.
+- This fix ensures that sockets get sufficient time to terminate gracefully.

+- Ensures consistent TLS alert behavior during handshake failure.
+
+## 2025-03-16 - 4.1.8 - fix(ConnectionHandler/tls)
+Change the TLS alert sent when a ClientHello lacks SNI: use the close_notify alert instead of handshake_failure to prompt immediate retry with SNI.
+
+- Replaced the previously sent handshake_failure alert (code 0x28) with a close_notify alert (code 0x00) in the TLS session resumption handling in ConnectionHandler.
+- This change encourages clients to immediately retry and include SNI when allowSessionTicket is false.
+
+## 2025-03-16 - 4.1.7 - fix(classes.pp.connectionhandler)
+Improve TLS alert handling in ClientHello when SNI is missing and session tickets are disallowed

+
+## 2025-03-16 - 4.1.5 - fix(TLS/ConnectionHandler)
+Improve handling of TLS session resumption without SNI by sending an 'unrecognized_name' alert instead of immediately terminating the connection. This change adds a grace period for the client to retry the handshake with proper SNI and cleans up the connection if no valid response is received.
+
+- Send a TLS warning (unrecognized_name alert, code 112) when a ClientHello is received without SNI and session tickets are disallowed.
+- Utilize socket cork/uncork to ensure the alert is sent as a single packet.
+- Add a 5-second alert timeout and a subsequent 30-second grace period to allow clients to initiate a new handshake with SNI.
+- Clean up and terminate the connection if no valid SNI is provided after the grace period, logging appropriate termination reasons.

+
+- Replace the fatal alert (0x02/0x40) with a warning alert (0x01/0x70) to notify clients to send SNI.
+- Use socket.write callback to wait 100ms after sending the alert before terminating the connection.
+- Remove the previous short (50ms) delay in favor of a more reliable delay mechanism before cleanup.
+
+## 2025-03-15 - 4.1.2 - fix(connectionhandler)

+- Applied these changes both for the initial ClientHello and when handling subsequent TLS data.
+
+## 2025-03-15 - 4.1.1 - fix(tls)
+Enforce strict SNI handling in TLS connections by terminating ClientHello messages lacking SNI when session tickets are disallowed and removing legacy session cache code.
+
+- In classes.pp.connectionhandler.ts, if allowSessionTicket is false and no SNI is extracted from a ClientHello, the connection is terminated to force a new handshake with SNI.

+- If the original config does not allow, search for an alternative domain config and validate IP rules.
+- Update the locked domain when allowed, ensuring connection reuse with valid certificate context.
+- Terminate the connection if no suitable domain config is found or IP restrictions are violated.
+
+## 2025-03-11 - 3.30.6 - fix(PortProxy)

 ## Usage
 
-`@push.rocks/smartproxy` is a comprehensive and versatile package designed to handle complex and high-volume proxying tasks efficiently. It includes features such as SSL redirection, port proxying, WebSocket support, and customizable routing and authentication mechanisms. This guide will provide a detailed walkthrough of how to harness these capabilities effectively. 
-
-### Initial Setup
-
-Before diving into specific features, let's start by configuring and setting up our basic proxy server:
+### 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 reverse proxy configurations
 const proxyConfigs = [
   {
-    destinationIp: '127.0.0.1',
-    destinationPort: '3000',
     hostName: 'example.com',
-    privateKey: `-----BEGIN PRIVATE KEY-----
-PRIVATE_KEY_CONTENT
------END PRIVATE KEY-----`,
-    publicKey: `-----BEGIN CERTIFICATE-----
-CERTIFICATE_CONTENT
------END CERTIFICATE-----`,
+    destinationIps: ['127.0.0.1'],
+    destinationPorts: [3000],
+    publicKey: 'your-cert-content',
+    privateKey: 'your-key-content',
+    rewriteHostHeader: true
   },
-  // More configurations can be added here
+  {
+    hostName: 'api.example.com',
+    destinationIps: ['127.0.0.1'],
+    destinationPorts: [4000],
+    publicKey: 'your-cert-content',
+    privateKey: 'your-key-content',
+    // Optional basic auth
+    authentication: {
+      type: 'Basic',
+      user: 'admin',
+      pass: 'secret'
+    }
+  }
 ];
 
-// Start the network proxy
-await myNetworkProxy.start();
-
-// Apply proxy configurations
-await myNetworkProxy.updateProxyConfigs(proxyConfigs);
-
-// Optionally add default headers to all responses
-await myNetworkProxy.addDefaultHeaders({
-  'X-Powered-By': 'smartproxy',
-});
+// Start the proxy and update configurations
+(async () => {
+  await proxy.start();
+  await proxy.updateProxyConfigs(proxyConfigs);
+  
+  // Add default headers to all responses
+  await proxy.addDefaultHeaders({
+    'Strict-Transport-Security': 'max-age=31536000; includeSubDomains; preload'
+  });
+})();
 ```
 
-### Configuring SSL Redirection
-
-One essential capability of a robust proxy server is ensuring that all HTTP traffic is redirected to secure HTTPS endpoints. This can be effortlessly accomplished using the `SslRedirect` class within `smartproxy`. This class listens on port 80 (HTTP) and redirects all incoming requests to HTTPS:
+### HTTP to HTTPS Redirection
 
 ```typescript
 import { SslRedirect } from '@push.rocks/smartproxy';
 
-// Instantiate the SslRedirect for listening on port 80
-const mySslRedirect = new SslRedirect(80);
-
-// Start listening and redirect HTTP traffic to HTTPS
-await mySslRedirect.start();
-
-// To stop redirection, you can use the following command:
-await mySslRedirect.stop();
+// Create and start HTTP to HTTPS redirect service on port 80
+const redirector = new SslRedirect(80);
+redirector.start();
 ```
 
-### Handling Complex Networking with Port Proxy
-
-Port proxying allows redirection of traffic from one port to another. This capability is crucial when dealing with services that need dynamic port forwarding, or when adapting to infrastructure changes without downtime. Smartproxy's `PortProxy` class handles this efficiently:
+### TCP Connection Handling with Domain-based Routing
 
 ```typescript
-import { PortProxy } from '@push.rocks/smartproxy';
+import { SmartProxy } from '@push.rocks/smartproxy';
 
-// Create a PortProxy to directly forward traffic from port 5000 to 3000
-const myPortProxy = new PortProxy(5000, 3000);
-
-// Initiate the port proxy
-await myPortProxy.start();
-
-// To stop the port proxy mechanism:
-await myPortProxy.stop();
-```
-
-Additionally, smartproxy's port proxying can support intricate scenarios where different forwarding rules are configured based on domain names or allowed IPs:
-
-```typescript
-import { PortProxy } from '@push.rocks/smartproxy';
-
-const myComplexPortProxy = new PortProxy({
-  fromPort: 6000,
-  toPort: 3000,
-  domains: [
+// Configure SmartProxy with domain-based routing
+const smartProxy = new SmartProxy({
+  fromPort: 443,
+  toPort: 8443,
+  targetIP: 'localhost', // Default target host
+  sniEnabled: true,      // Enable SNI inspection
+  
+  // Enhanced reliability settings
+  initialDataTimeout: 60000,        // 60 seconds for initial TLS handshake
+  socketTimeout: 3600000,           // 1 hour socket timeout
+  maxConnectionLifetime: 3600000,   // 1 hour connection lifetime
+  inactivityTimeout: 3600000,       // 1 hour inactivity timeout
+  maxPendingDataSize: 10 * 1024 * 1024, // 10MB buffer for large TLS handshakes
+  
+  // Browser compatibility enhancement
+  enableTlsDebugLogging: false,     // Enable for troubleshooting TLS issues
+  
+  // Port and IP configuration
+  globalPortRanges: [{ from: 443, to: 443 }],
+  defaultAllowedIPs: ['*'], // Allow all IPs by default
+  
+  // Socket optimizations for better connection stability
+  noDelay: true,                    // Disable Nagle's algorithm
+  keepAlive: true,                  // Enable TCP keepalive
+  enableKeepAliveProbes: true,      // Enhanced keepalive for stability
+  
+  // Domain-specific routing configuration
+  domainConfigs: [
     {
-      domain: 'api.example.com',
-      allowedIPs: ['192.168.0.*', '127.0.0.1'],
-      targetIP: '192.168.1.100'
+      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 }],
+      connectionTimeout: 7200000                 // Domain-specific timeout (2 hours)
     }
-    // Define more domain-specific rules if needed
   ],
-  sniEnabled: true,  // if SNI (Server Name Indication) is desired
-  defaultAllowedIPs: ['*']);
+  
+  preserveSourceIP: true
 });
 
-// Start listening for complex routing requests
-await myComplexPortProxy.start();
+smartProxy.start();
 ```
 
-### WebSocket Support and Load Handling
-
-With the advent of real-time applications, efficient WebSocket handling in proxies is crucial. Smartproxy integrates WebSocket support seamlessly, enabling it to proxy WebSocket traffic while maintaining security and performance:
+### NfTables Port Forwarding
 
 ```typescript
-import { NetworkProxy } from '@push.rocks/smartproxy';
+import { NfTablesProxy } from '@push.rocks/smartproxy';
 
-const wsProxy = new NetworkProxy({ port: 443 });
-
-// Assume reverse proxy configurations with WebSocket intentions
-const wsProxyConfigs = [
-  {
-    destinationIp: '127.0.0.1',
-    destinationPort: '8080',
-    hostName: 'socket.example.com',
-    // Add further options such as keys for SSL if needed
-  }
-];
-
-// Start the network proxy with WebSocket capabilities
-await wsProxy.start();
-await wsProxy.updateProxyConfigs(wsProxyConfigs);
-
-// Ensure WebSocket connections remain alive
-wsProxy.heartbeatInterval = setInterval(() => {
-  // logic for keeping connections alive and healthy
-}, 60000); // Every 60 seconds
-
-// Gracefully handle server or connection errors to maintain uptime
-wsProxy.httpsServer.on('error', (error) => console.log('Server Error:', error));
-```
-
-### Comprehensive Routing and Advanced Features
-
-Smartproxy supports dynamic and customizable request routing based on the incoming request's destination. This feature enables extensive use-case scenarios, from simple API endpoint redirection to elaborate B2B service integrations:
-
-```typescript
-import { NetworkProxy } from '@push.rocks/smartproxy';
-
-const dynamicRoutingProxy = new NetworkProxy({ port: 8443 });
-dynamicRoutingProxy.router.setNewProxyConfigs([
-  {
-    destinationIp: '192.168.1.150',
-    destinationPort: '80',
-    hostName: 'dynamic.example.com',
-    authentication: {
-      type: 'Basic',
-      user: 'admin',
-      pass: 'password123'
-    }
-  }
-]);
-
-await dynamicRoutingProxy.start();
-```
-
-For those dealing with high volume or regulatory needs, the integration of tools like `iptables` allows broad control over network traffic:
-
-```typescript
-import { IPTablesProxy } from '@push.rocks/smartproxy';
-
-// Setting up iptables for advanced network management
-const ipTablesProxy = new IPTablesProxy({
-  fromPort: 8081,
+// Basic usage - forward single port
+const basicProxy = new NfTablesProxy({
+  fromPort: 80,
   toPort: 8080,
-  deleteOnExit: true // clean rules upon server shutdown
+  toHost: 'localhost',
+  preserveSourceIP: true,
+  deleteOnExit: true  // Automatically clean up rules on process exit
 });
 
-// Begin routing with IPTables
-await ipTablesProxy.start();
-```
-
-### Combining with HTTP and HTTPS Credentials
-
-When undertaking proxy configurations, handling sensitive data like SSL certificates and keys securely is imperative:
-
-```typescript
-import { loadDefaultCertificates } from '@push.rocks/smartproxy';
-
-try {
-  const { privateKey, publicKey } = loadDefaultCertificates(); // adjust path as needed
-  console.log('Certificates loaded.');
-  // Use these certificates in your SSL-based configurations
-} catch (error) {
-  console.error('Cannot load certificates:', error);
-}
-```
-
-### Testing and Validation
-
-Given these powerful capabilities, rigorous testing of configurations and functionality using frameworks like `tap` can ensure high-quality and reliable proxy configurations. Smartproxy integrates with Typescript test setups:
-
-```typescript
-import { expect, tap } from '@push.rocks/tapbundle';
-import { NetworkProxy } from '@push.rocks/smartproxy';
-
-tap.test('proxied request should return status 200', async () => {
-  // Your test logic here
+// Forward port ranges
+const rangeProxy = new NfTablesProxy({
+  fromPort: { from: 3000, to: 3010 },  // Forward ports 3000-3010
+  toPort: { from: 8000, to: 8010 },    // To ports 8000-8010
+  protocol: 'tcp',                     // TCP protocol (default)
+  ipv6Support: true,                   // Enable IPv6 support
+  enableLogging: true                  // Enable detailed logging
 });
 
-tap.start();
+// Multiple port specifications with IP filtering
+const advancedProxy = new NfTablesProxy({
+  fromPort: [80, 443, { from: 8000, to: 8010 }],  // Multiple ports/ranges
+  toPort: [8080, 8443, { from: 18000, to: 18010 }],
+  allowedSourceIPs: ['10.0.0.0/8', '192.168.1.0/24'],  // Only allow these IPs
+  bannedSourceIPs: ['192.168.1.100'],                 // Explicitly block these IPs
+  useIPSets: true,                                   // Use IP sets for efficient IP management
+  forceCleanSlate: false                             // Clean all NfTablesProxy rules before starting
+});
+
+// Advanced features: QoS, connection tracking, and NetworkProxy integration
+const advancedProxy = new NfTablesProxy({
+  fromPort: 443,
+  toPort: 8443,
+  toHost: 'localhost',
+  useAdvancedNAT: true,                // Use connection tracking for stateful NAT
+  qos: {
+    enabled: true,
+    maxRate: '10mbps',                 // Limit bandwidth
+    priority: 1                        // Set traffic priority (1-10)
+  },
+  netProxyIntegration: {
+    enabled: true,
+    redirectLocalhost: true,           // Redirect localhost traffic to NetworkProxy
+    sslTerminationPort: 8443           // Port where NetworkProxy handles SSL
+  }
+});
+
+// Start any of the proxies
+await basicProxy.start();
 ```

+## Advanced Features
+
+### TLS Handshake Optimization
+
+The enhanced `SmartProxy` implementation includes significant improvements for TLS handshake handling:
+
+- Robust SNI extraction with improved error handling
+- Increased buffer size for complex TLS handshakes (10MB)
+- Longer initial handshake timeout (60 seconds)
+- Detection and tracking of TLS connection states
+- Optional detailed TLS debug logging for troubleshooting
+- Browser compatibility fixes for Chrome certificate errors
+
+```typescript
+// Example configuration to solve Chrome certificate errors
+const portProxy = new SmartProxy({
+  // ... other settings
+  initialDataTimeout: 60000,            // Give browser more time for handshake
+  maxPendingDataSize: 10 * 1024 * 1024, // Larger buffer for complex handshakes
+  enableTlsDebugLogging: true,          // Enable when troubleshooting
+});
+```
+
+### Connection Management and Monitoring
+
+The `SmartProxy` class includes built-in connection tracking and monitoring:
+
+- Automatic cleanup of idle connections with configurable timeouts
+- Timeouts for connections that exceed maximum lifetime
+- Detailed logging of connection states
+- Termination statistics
+- Randomized timeouts to prevent "thundering herd" problems
+- Per-domain timeout configuration
+
+### WebSocket Support
+
+The `NetworkProxy` class provides WebSocket support with:
+
+- WebSocket connection proxying
+- Automatic heartbeat monitoring
+- Connection cleanup for inactive WebSockets
+
+### SNI-based Routing
+
+The `SmartProxy` class can inspect the SNI (Server Name Indication) field in TLS handshakes to route connections based on the requested domain:
+
+- Multiple backend targets per domain
+- Round-robin load balancing
+- Domain-specific allowed IP ranges
+- Protection against SNI renegotiation attacks
+
+### Enhanced NfTables Management
+
+The `NfTablesProxy` class offers advanced capabilities:
+
+- Support for multiple port ranges and individual ports
+- More efficient IP filtering using nftables sets
+- IPv6 support with full feature parity
+- Quality of Service (QoS) features including bandwidth limiting and traffic prioritization
+- Advanced connection tracking for stateful NAT
+- Robust error handling with retry mechanisms
+- Structured logging with JSON support
+- NetworkProxy integration for SSL termination
+- Comprehensive cleanup on shutdown
+
+### Port80Handler with Glob Pattern Support
+
+The `Port80Handler` class includes support for glob pattern domain matching:
+
+- Supports wildcard domains like `*.example.com` for HTTP request routing
+- Detects glob patterns and skips certificate issuance for them
+- Smart routing that first attempts exact matches, then tries pattern matching
+- Supports forwarding HTTP requests to backend services
+- Separate forwarding configuration for ACME challenges
+
+## Troubleshooting
+
+### Browser Certificate Errors
+
+If you experience certificate errors in browsers, especially in Chrome, try these solutions:
+
+1. **Increase Initial Data Timeout**: Set `initialDataTimeout` to 60 seconds or higher
+2. **Increase Buffer Size**: Set `maxPendingDataSize` to 10MB or higher
+3. **Enable TLS Debug Logging**: Set `enableTlsDebugLogging: true` to troubleshoot handshake issues
+4. **Enable Keep-Alive Probes**: Set `enableKeepAliveProbes: true` for better connection stability
+5. **Check Certificate Chain**: Ensure your certificate chain is complete and in the correct order
+
+```typescript
+// Configuration to fix Chrome certificate errors
+const smartProxy = new SmartProxy({
+  // ... other settings
+  initialDataTimeout: 60000,
+  maxPendingDataSize: 10 * 1024 * 1024,
+  enableTlsDebugLogging: true,
+  enableKeepAliveProbes: true
+});
+```
+
+### Connection Stability
+
+For improved connection stability in high-traffic environments:
+
+1. **Set Appropriate Timeouts**: Use longer timeouts for long-lived connections
+2. **Use Domain-Specific Timeouts**: Configure per-domain timeouts for different types of services
+3. **Enable TCP Keep-Alive**: Ensure `keepAlive` is set to `true`
+4. **Monitor Connection Statistics**: Enable detailed logging to track termination reasons
+5. **Fine-tune Inactivity Checks**: Adjust `inactivityCheckInterval` based on your traffic patterns
+
+### NfTables Troubleshooting
+
+If you're experiencing issues with NfTablesProxy:
+
+1. **Enable Detailed Logging**: Set `enableLogging: true` to see all rule operations
+2. **Force Clean Slate**: Use `forceCleanSlate: true` to remove any lingering rules
+3. **Use IP Sets**: Enable `useIPSets: true` for cleaner rule management
+4. **Check Permissions**: Ensure your process has sufficient permissions to modify nftables
+5. **Verify IPv6 Support**: If using `ipv6Support: true`, ensure ip6tables is available
