Install OpenVPN Access Server on Debian

 Install Debian on a box.  This example has it being installed on ProxMox

Did a standard installation of Debian 13.2.0

The only 'additional' option I added at time of install was the SSH server.

Once installed the box was patched

sudo apt update && sudo apt upgrade -y

Then the following command was run (from the access server install on the openVPN site).  And it did the whole thing for this installation.

bash <(curl -fsS https://packages.openvpn.net/as/install.sh) --yes

My installation didn't come with CURL so it errored, you can install CURL this way
sudo apt install curl

It will go through a bunch of installation routines.  

You should note that the installation will generate a user/password during install.   It will look something like this:


When you get a "Installation successful!" response.  You should be able to HTTPS to the box

https://IPofServer:943/admin


Enter in your credentials

openvpn / XTI5Xj8Fqy2e

You'll get prompted with a License Agreement


You'll be in the GUI now


Change the GUI openvpn admin password

Goto USERS -> OpenVPN -> Reset Password
