ProxyBridge v4.0.0

Platform Notice: v4.0.0 is currently available for Windows only. Linux and macOS builds are in pre-development and will be released in a future update.

✨ New Features

🌐 IPv6 Support #78

Full IPv6 support across logging, routing, and proxy - ProxyBridge now handles IPv6 end-to-end.

🔀 Multiple Proxy Configurations #44

Save multiple proxy configurations and assign different proxies to different rules simultaneously. No more swapping configs manually.

👤 Profiles #98

Create, switch, import, and export profiles - each profile bundles your full ProxyBridge configuration into a single portable file, making it easy to manage separate setups for different use cases.

🌍 Domain Name Forwarding #138

ProxyBridge now sends domain names directly to the proxy server instead of resolving them locally first, enabling proper remote DNS resolution. Closes #138.

🔍 Log Filters #97 #150

Filter connection logs by process, IP, port, protocol, and action using include/exclude rules with wildcard support.

⚡ Toolbar Quick Actions #102

Proxy rules and config are now accessible directly from the main toolbar.

🧹 Auto-Clear Connection Logs

Optionally auto-trim connection logs when they exceed the configured limit.

🖥️ CLI Rewritten in C

The CLI has been rewritten from scratch - migrated from C# to C for improved performance and portability.

🐛 Bug Fixes

• Relay sockets loopback fix - Relay sockets were bound to loopback only; now binds to INADDR_ANY so real traffic reaches the relay correctly (TCP + UDP)
• SOCKS5 UDP ASSOCIATE 0.0.0.0 fix - Now substitutes the proxy's resolved IP, resolving Winsock error 10049
• Disabled proxy rules not persisting - Disabled rule state is now correctly saved and restored on startup and profile switch #107
• ++ in process names - Processes like notepad++.exe were rejected by the rule validator; now handled correctly. Closes #157
• Log filter Save clearing entries - Saving a log filter no longer clears existing log entries; it now re-filters in place
• UDP - Multiple UDP bugs fixed; real-time UDP communication now fully supported #172 #89
• UDP Session Termination - UDP sessions are now properly terminated #133
• ICMP - ICMP handling issues resolved
• Loopback address - Loopback address routing issues fixed
• Proxy rule wildcard - Wildcard matching errors in proxy rules fixed #93
• Rule disabled state - Fixed rules not staying disabled after restart #107
• Memory leak - Fixed memory leak caused by timed-out sessions not being cleaned up
• ESC key - ESC now closes popup windows. Closes #152
• UI/UX - Multiple UI fixes including proxy config and rule shortcuts on the home screen #101
• Binary optimizations - Reduced binary size and improved startup performance
• Proxy rule engine - Internal rule matching optimized
• Minimize - Fixed Windows Minimize isses #142

🗑️ Removed

• DNS via Proxy - Removed the DNS via Proxy feature along with all associated UI, settings, and C-layer code. Use Domain Name Forwarding instead for remote DNS resolution.
