Well, I still have some problems establishing a working OpenVPN Connection. So first, Iam running a main OpenWRT-Router with a working OpenVPN configuration. My Windows-Machine connects pretty well all the time to my main OpenVPN-Server (Router). I made anonther Key for the new project: Connect the mobile GL.iNet X750 with OpenVPN with my main router at home.
Both Routers connect and a working, a green VPN-connection is shown. But connect by wifi with any device to the X750 there is no WWW-connection. Even with the X750 I can ping all my local network devices at home as aspected (using SSH). But with a wifi-connected device I have no connection to the local devices at the main router at home.
My configuration:

# This configuration can be used by multiple #
# clients, however each client should have #
# its own cert and key files. #
# #
# On Windows, you might want to rename this #
# file so it has a .ovpn extension #

on the Server I made a clientspecific config file in /etc/openvpn/dir with the content “push “redirect-gateway””, the same as client-specific for my windows-connection.
Do there anybody having ideas to solve?
