 # Changelog
 
+## 2025-03-07 - 3.29.2 - fix(PortProxy)
+Fix test for PortProxy handling of custom IPs in Docker/CI environments.
+
+- Ensure compatibility with Docker/CI environments by standardizing on 127.0.0.1 for test server setup.
+- Simplify test configuration by using a unique port rather than different IPs.
+
+## 2025-03-07 - 3.29.1 - fix(readme)
+Update readme for IPTablesProxy options
+
+- Add comprehensive examples for IPTablesProxy usage.
+- Expand IPTablesProxy settings with IPv6, logging, and advanced features.
+- Clarify option defaults and descriptions for IPTablesProxy.
+- Enhance 'Troubleshooting' section with IPTables tips.
+
 ## 2025-03-07 - 3.29.0 - feat(IPTablesProxy)

 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
