If you run OpenVPN directly on your OpenWRT router, it usually hijacks your entire internet connection. But what if you only want specific apps, websites, or devices to use the VPN?

By combining OpenVPN with PassWall2 and Sing-Box, you can convert your VPN connection into a flexible proxy node.

Why do this? (Use Cases)

Smart Routing: Route only specific traffic (like foreign streaming sites or blocked services) through the VPN, while keeping your local traffic on your fast, regular ISP connection.

Local SOCKS Proxy: Expose the OpenVPN connection as a SOCKS proxy that anyone on your local Wi-Fi network can manually connect to.
