 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
