Describe the Feature

Feature Description

I would like to request adding a network interface selection feature for proxy rules, similar to how Proxifier works.

In Proxifier, users can specify a specific network interface (e.g., WLAN, Ethernet, VPN adapter) for each proxy rule, allowing fine-grained control over which network path the application traffic uses.

Use Case

This is especially useful for scenarios like:

• Routing specific application traffic through a VPN/WLAN adapter while other traffic uses the default interface.
• Testing connectivity over different physical/virtual network interfaces.
• Avoiding conflicts with multiple active network connections (e.g., physical Ethernet + virtual VMware adapters + VPN tunnels).

Screenshot Reference

I've attached a screenshot from Proxifier showing the "Advanced Rule Settings" where the network interface dropdown is available for selection.
