I have a rather peculiar #Android problem.
- I use personalDNSfilter (https://www.zenz-solutions.de/personaldnsfilter-wp/) to block ads system-wide. It's basically like running a local pi-hole using a local VPN.
- I would also like to use Orbot ( #Tor) and run some apps (specifically Nextcloud) that don't natively support proxying through Orbot's VPN.

The problem is, Android won't let me run two VPNs at the same time. And blocking ads without a VPN would require rooting my phone, which I don't want to do. However:
- personalDNSfilter can expose the DNS server on port 5300 without using the VPN (which is useless in itself).
- Orbot can expose its HTTP and SOCKS proxy without using the VPN (which is also useless in itself).

Is there some way to setup a custom VPN that would combine these two things, i.e., let me route some apps through Orbot's proxy and use the local DNS server (provided by personalDNSfilter) at port 5300? I was looking at OpenVPN for Android (https://github.com/schwabe/ics-openvpn), but I'm honestly really confused. Help please? 😅 Boosts appreciated.
