Open VPN between gl.inet gl-ar750s-ext Slate and Asus RT-AC68U

[5teve]

@elorimer

If the slate connects to your 68U and you can browse the LAN, but the devices connected to the slate can’t access the internet, then it might be your default gateway is being changed. Look at the client configuration and make sure it doesn’t have something like “redirect-gateway def1”, and look at the server configuration and make sure it doesn’t have something like “push redirect-gateway”. You can find the server configuration at /tmp/etc/openvpn/server1 or /tmp/etc/openvpn/server2

Thanks again for your continued guidance… so SSH into router…

OK so client ovpn file is…
