[feature] Easy way to exclude a network interface

Version and OS
0.52.9 bare metal debian (Proxmox LXC)

Is your feature request related to a problem? Please describe.
Yes, I use a VPN service (OpenVPN) and use the following URL to make sure it uses the VPN:

ws://localhost:3000?stealth=1&--disable-web-security&--ignore-certificate-errors&--lang=de-CH&--timezone=Europe/UTC&--window-size=1366,768&--user-agent=Mozilla/5.0%20(Windows%20NT%2010.0;%20Win64;%20x64)%20AppleWebKit/537.36%20(KHTML,%20like%20Gecko)%20Chrome/129.0.0.0%20Safari/537.36&--netifs-to-ignore=eth0@if52

notice the end where I exclude the default network interface, now the problem is that the number after eth0 is changing after each reboot of the LXC, so I manually need to update this each time I restart the lxc.

Describe the solution you'd like
I search a better solution for force a specific extra browser through the vpn.

Describe the use-case and give concrete real-world examples
This would make it easier to use VPN or other extra interfaces.

Just to clarify, exclude the network interface from what exactly?

@dgtlmoon
well in does not really need to be exclude, include would work too, I honestly just need a way to tell changedetection, for this browser use the vpn interface and for this browser do not use it.

To be used for the browser and therefore the checking of websites, as some are hard on blocking foreign bots but have less restrictions if the "bot" is from their own country.

That's at the operating system levels like your default routes and what nots right? Or you can set a proxy?

[CrazyWolf13]

I want, for example one extra browser to use my vpn interface tun0 and one extra browser to not use it, so I need either some argument I can pass to the browser or an option in changedetection.

Please take a look at the above launch url, while that works fine for my use case, the problem is, that the interface name changes on reboots.
Is there a changedetection API I could use to dynamically update the launch url, or any other good idea?

netifs-to-ignore is a chrome option.. I think this out of our scope

I'll shuffle it to discussions until some nice ideas come
