Can't use VPN on mobile data

    kamikaze2112 , Jan 12, 2020 :
    Tried both OpenVPN server and a generic ipsec over l2tp vpn to access my home network. Both will connect to my server, but then can't browse anything (internet or local network). I can ping devices on my lan, and resolve web addresses from a terminal while connected, it just won't browse anything using a browser, or other apps such as the play store.

    The exact same OpenVPN client config and server works as expected on my old op3t when I pop the sim back in it. It also works fine if I'm on wifi. So there's something going on with the 7 pro that I can't seem to put my finger on. the OpenVPN guys can't seem to figure it out, so I'm trying here as a last resort. I may flash a 3rd party rom to see if it's something in OxygenOS, or something with the hardware. Just really strange that my old op3t works running Android 9, and this doesn't with the same config.
