Hi all,

I need some help.

I have installed the latest OpenVPN version by using the description on the OpenVPN page (https://openvpn.net/download-open-vpn/) on my Intel Nuc computer on which I have installed Ubuntu 18.4.

The installation was completely done and I was also able to login to the OpenSVN admin page. It is also possible to connect my client (Mac) via OpenVPN Connect and I am also receiving the message that I am successfully connected (In the OpenVPN Connect itself and also on the server side). Unfortunatelly I cannot establish any communication to the internet (e.g www.google.com).

Is there something what I have missed to configure and could anyone of you please help to solve this issue? Please let me know in case of any logs are needed.

best regards

TinCanTech has already given me How To Link (viewtopic.php?f=30&t=22603)

Unfortunatelly I cannot find any server.conf files on my PC although I have searched for the file server.conf on my machine.

As written in my first post I have done the installation as described here: https://openvpn.net/download-open-vpn/
After that I have followed the quick starter guide: https://openvpn.net/vpn-server-resource ... ss-server/

I am aware that you are struggling with a lot of such requests every day. I would like to appologize for that and hope that someone can help me.

You are not using Access Server so don't read the wrong documentation.
