Red-Team-Infrastructure-Wiki VS openvpn-install

I found this as a useful starting point: https://github.com/bluscreenofjeff/Red-Team-Infrastructure-Wiki

We have done it by connecting a Huawei LTE-Stick to a Raspberry Pi with Kali Linux. It automatically sets up a VPN connection to a control server in AWS where we have red teaming infrastructure set up. When we then connect the rpi into the network we can do some SSH port forwarding and connect to the rpi, which is now a network implant where we can do basically anything from. This sometimes requires finding Active Directory credentials around the office or through a phishing campaign (really easy with the access to the local network) or something, in order to get a foothold onto the AD infrastructure.

and for OpenVPN: https://github.com/Nyr/openvpn-install

I'm trying to establish a private torrenting setup using qBittorrent on my local whitebox server machine using Ubuntu 22.04 and a Virtual Private Server (VPS) as a VPN using Ubuntu 22.04 and OpenVPN (I used https://github.com/Nyr/openvpn-install). My local machine, acting as a private tracker seedbox, has qBittorrent installed and configured to use port 15986 for inbound connections with tun0 as the network interface.

Hello, I installed an OpenVPN server on my Centos server using the easy install script here https://github.com/Nyr/openvpn-install.git My client is MacOS and it works fine for the most part BUT I need to access devices on the server's LAN When I'm using my home internet, I can access the server fine but everything that is not in the same subnet as what OpenVPN gave me does not work. When using LTE and network sharing on my computer, I can still access the server and now I can also access devices on the server's LAN that is not in the same subnet as OpenVPN. I don't understand why it behave like this and I want to always be able to access the server's LAN when connecting to the VPN.

My idea would be to create a Debian VM on Proxmox, and install OpenVPN using Nyr script (https://github.com/Nyr/openvpn-install) and create a user for each of my friends.
