TunnlTo – Windows WireGuard split tunnel client built with Rust, Tauri
Hi Everyone, TunnlTo is a tool for controlling which Windows applications, processes, and IP addresses can use a WireGuard VPN tunnel. Here are some examples of how it could be used: - Route only FireFox through a privacy VPN - Route Slack and Microsoft Office through a work VPN - Route a game through a gaming VPN - Stop a game from routing through a privacy VPN - Stop a browser from routing through a work VPN - Route a specific IP address range through a privacy VPN - Route all traffic through a privacy VPN except a specific IP address range I have been collaborating on this project with…
In plain words
TunnlTo is a Windows application that selectively routes traffic through WireGuard VPN tunnels based on applications, processes, or IP addresses. Built with Rust and Tauri, it allows users to choose which programs use which VPN connections—for example, routing only Firefox through a privacy VPN while excluding others, or creating exceptions for specific IP ranges. The tool is designed for users who need granular control over VPN routing for privacy, work, gaming, or other purposes.

Hi Everyone, TunnlTo is a tool for controlling which Windows applications, processes, and IP addresses can use a WireGuard VPN tunnel.

"WireSock VPN Client is a lightweight command line WireGuard VPN client for Windows that has advanced features not available in the official WireGuard for Windows such as selective application tunneling and disallowed IP addresses. WireSock VPN Client combines the power of Windows Packet Filter and BoringTun (user space WireGuard implementation in Rust) to provide exceptional performance, security and scalability." The TunnlTo app is built with Tauri and I've used boring old HTML, CSS (bootstrap) and JavaScript as I had major JS framework fatigue. I have previously built a production app with Electron and Vue. Tauri appealed to me for its use of Rust and its small installation sizes. I tried Tauri pre version 1.0 and had a bit of trouble but this time around its been a positive experience. The docs and the Discord community have come a long way. I would appreciate any feedback about the project so I can get an idea of what direction to take it in next. Vadim will be around a little later if anyone is curious about the WireGuard implementation and wants to know more. Thanks for reading!

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma...

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
