Hello, I am using an internet proxy with OVPN (IPFire project) and a phone with UT 24.04 (Pixel 3Axl). The VPN works both for accessing the local network and as a proxy for accessing, for example, the web from a mobile phone. (There were problems with the encryption type on the ovpn server side.)
I will add:
On the server side, I changed the encryption type from AES-GCM 256-bit to CBC 256-bit, and
then added the PKCS12 certificate to the phone...
