 # Changelog
 
+## 2025-03-11 - 3.30.8 - fix(core)
+No changes in this commit.
+
+
+## 2025-03-11 - 3.30.7 - fix(PortProxy)
+Improve TLS renegotiation SNI handling by first checking if the new SNI is allowed under the existing domain config. If not, attempt to find an alternative domain config and update the locked domain accordingly; otherwise, terminate the connection on SNI mismatch.
+
+- Added a preliminary check against the original domain config to allow re-handshakes if the new SNI matches allowed patterns.
+- 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)
+Improve TLS renegotiation handling in PortProxy by validating the new SNI against allowed domain configurations. If the new SNI is permitted based on existing IP rules, update the locked domain to allow connection reuse; otherwise, terminate the connection to prevent misrouting.
+
+- Added logic to check if a new SNI during renegotiation is allowed by comparing IP rules from the matching domain configuration.
+- Updated detailed logging to indicate when a valid SNI change is accepted and when it results in a mismatch termination.
+
+## 2025-03-10 - 3.30.5 - fix(internal)
+No uncommitted changes detected; project files and tests remain unchanged.
+

 ## 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
+- 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
 
@@ -385,6 +490,61 @@ The `PortProxy` class can inspect the SNI (Server Name Indication) field in TLS
 - 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
