 # Changelog
 
+## 2025-03-17 - 4.2.1 - fix(core)
+No uncommitted changes detected in the project.
+
+
+## 2025-03-17 - 4.2.0 - feat(tlsalert)
+add sendForceSniSequence and sendFatalAndClose helper functions to TlsAlert for improved SNI enforcement
+
+- Introduce sendForceSniSequence to combine multiple alerts and force clients to provide SNI
+- Add sendFatalAndClose to immediately send a fatal alert and close the connection
+- 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.
+- Introduced alertFallbackTimeout property in connection records to track fallback timeout and ensure proper cleanup.
+- Extended the delay before closing the connection after sending an alert, providing the client more time to retry.
+
+## 2025-03-17 - 4.1.15 - fix(connectionhandler)
+Delay socket termination in TLS session resumption handling to allow proper alert processing
+
+- Removed the immediate socket.end() call in finishConnection and moved it inside the setTimeout, ensuring that clients (especially Chrome) have additional time to process the TLS alert before connection termination
+- This prevents premature socket closure on ClientHello without SNI when session tickets are disallowed
+
+## 2025-03-17 - 4.1.14 - fix(ConnectionHandler)
+Use the correct TLS alert data and increase the delay before socket termination when session resumption without SNI is detected.
+
+- Replaced certificateExpiredAlert with serverNameUnknownAlertData for sending the appropriate alert.
+- Increased the cleanup delay from 1000ms to 5000ms to allow a more graceful termination.
+
+## 2025-03-17 - 4.1.13 - fix(tls-handshake)
+Set certificate_expired TLS alert level to warning instead of fatal to allow graceful termination.
+
+- In the TLS handshake alert for certificate_expired (0x2F), changed the alert level from 0x02 (fatal) to 0x01 (warning).
+- This change avoids abrupt connection termination, enabling a smoother handling of certificate expiration alerts.
+
+## 2025-03-17 - 4.1.12 - fix(classes.pp.connectionhandler)
+Replace unrecognized_name alert data with certificate_expired alert in TLS handshake handling for session resumption without SNI
+
+- 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.
+
+## 2025-03-16 - 4.1.10 - fix(connectionhandler)
+Increase delay timings for TLS alert transmission in session ticket blocking to allow graceful socket termination
+
+- Updated finishConnection: replaced immediate socket.destroy with a graceful end call
+- Increased delay after successful write from 50ms to 200ms to allow alert processing

+## 2025-03-16 - 4.1.9 - fix(ConnectionHandler)
+Replace closeNotify alert with handshake failure alert in TLS ClientHello handling to properly signal missing SNI and enforce session ticket restrictions.
+
+- Switched alert data sent on missing SNI from closeNotifyAlert to sslHandshakeFailureAlertData.
+- 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
+
+- Replace the unrecognized_name alert with a handshake_failure alert to ensure better client behavior.
+- Refactor the alert sending mechanism using cork/uncork and add a safety timeout for the drain event.
+- Enhance logging for debugging TLS handshake failures when SNI is absent.
+
+## 2025-03-16 - 4.1.6 - fix(tls)
+Refine TLS ClientHello handling when allowSessionTicket is false by replacing extensive alert timeout logic with a concise warning alert and short delay, encouraging immediate client retry with proper SNI
+
+- Update the TLS alert sending mechanism to use cork/uncork and a short, fixed delay instead of long timeouts
+- Remove redundant event listeners and excessive cleanup logic after sending the alert
+- Improve code clarity and encourage clients (e.g., Chrome) to retry handshake with SNI more responsively
+
+## 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.
+
+## 2025-03-15 - 4.1.4 - fix(ConnectionHandler)

+
+## 2025-03-15 - 4.1.3 - fix(connectionhandler)
+Improve handling of TLS ClientHello messages when allowSessionTicket is disabled and no SNI is provided by sending a warning alert (unrecognized_name, code 0x70) with a proper callback and delay to ensure the alert is transmitted before closing the connection.
+
+- 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)
+Send proper TLS alert before terminating connections when SNI is missing and session tickets are disallowed.
+
+- Added logic to transmit a fatal TLS alert (Handshake Failure) before closing the connection when no SNI is present with allowSessionTicket=false.
+- Introduced a slight 50ms delay after sending the alert to ensure the client receives the alert properly.
+- 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.
+- In classes.pp.snihandler.ts, removed session cache and related cleanup functions used for tab reactivation, simplifying SNI extraction logic.

+```
 
 ## 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',
-    destinationPort: '3000',
     hostName: 'example.com',
-    privateKey: `-----BEGIN PRIVATE KEY-----
-PRIVATE_KEY_CONTENT
------END PRIVATE KEY-----`,
-    publicKey: `-----BEGIN CERTIFICATE-----
-CERTIFICATE_CONTENT
------END CERTIFICATE-----`,
+    destinationIp: '127.0.0.1',
+    destinationPort: 3000,
+    publicKey: 'your-cert-content',
+    privateKey: 'your-key-content'
   },
-  // Add more reverse proxy configurations here
+  {
+    hostName: 'api.example.com',
+    destinationIp: '127.0.0.1',
+    destinationPort: 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();
-
-// Update proxy configurations dynamically
-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'
+  });
+})();
 ```
 
-### 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
+  
+  // 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: [
+    {
+      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)
+    }
+  ],
+  
+  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';
+
+// Basic usage - forward single port
+const basicProxy = new IPTablesProxy({
+  fromPort: 80,
+  toPort: 8080,
+  toHost: 'localhost',
+  preserveSourceIP: true,
+  deleteOnExit: true  // Automatically clean up rules on process exit
+});
+
+// Forward port ranges
+const rangeProxy = new IPTablesProxy({
+  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
+});
+
+// Multiple port specifications with IP filtering
+const advancedProxy = new IPTablesProxy({
+  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
+  addJumpRule: true,                                  // Use custom chain for better management
+  checkExistingRules: true                           // Check for duplicate rules
+});
+
+// NetworkProxy integration for SSL termination
+const sslProxy = new IPTablesProxy({
+  fromPort: 443,
+  toPort: 8443,
+  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();
+```
+
+### Automatic HTTPS Certificate Management
+
+```typescript
+import { Port80Handler } from '@push.rocks/smartproxy';
+
+// Create an ACME handler for Let's Encrypt
+const acmeHandler = new Port80Handler();

+## Advanced Features
+
+### TLS Handshake Optimization
+
+The enhanced `PortProxy` 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 PortProxy({
+  // ... 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 `PortProxy` 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 `PortProxy` 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 IPTables Management
+
+The improved `IPTablesProxy` class offers advanced capabilities:
+
+- Support for multiple port ranges and individual ports
+- IPv6 support with ip6tables
+- Source IP filtering with allow/block lists
+- Custom chain creation for better rule organization
+- NetworkProxy integration for SSL termination
+- Automatic rule existence checking to prevent duplicates
+- Comprehensive cleanup on shutdown
+
+## 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 portProxy = new PortProxy({
+  // ... 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
+
+### IPTables Troubleshooting
+
+If you're experiencing issues with IPTablesProxy:
+
+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 Custom Chains**: Enable `addJumpRule: true` for cleaner rule management
+4. **Check Permissions**: Ensure your process has sufficient permissions to modify iptables
+5. **Verify IPv6 Support**: If using `ipv6Support: true`, ensure ip6tables is available
