openvpn-install VS wireguard-install

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.

Btw you can try this script..

If you want an easy setup I suggest using a script like this. Even a novice should be able to set up Wireguard in about half an hour - assuming they already have a DynDNS service set up.

Really depends on what you want to do. I run an Ubuntu server VM with Wireguard (my preferred script) , an openmediavault VM to take care or my NAS, HDDs (SATA controller is passed through) with mergerFS+Snapraid) and it also serves as my docker host, pihole VM for DNS (also allows you create your own, local DNS entries so you do not have to use the device's IP)

Yes, and no. Server security is a rather complex topic and covering it in a few sentences is impossible. Try to expose as few of your services as possible to the open web and also ensure they are well maintained - on your side (AKA update your stuff regular) and on the dev side. Seeing that the last github update was over ~6 months ago likely means there are unmitigated security risks. You can expect large projects like Plex, Nextcloud, Bitwarden(Vaultwarden), and others to be built well enough that they do not pose a significant risk. Anything else should only be accessible over a VPN. I am not talking about the commercial ones like PIA or NordVPN. These are mainly useful to circumvent geo restrictions, get better peering, and some other stuff. In terms of security, it does almost nothing despite what the ads claim. What I am talking about is running your own VPN server. Easily doable when you run a home server anyway by running a Wireguard script. By connecting to it remotely you will be able to access your home network as if you were at home although a bit bandwidth limited due to slow internet connections.

but if you don't then this is probably fine as well but I never used it https://github.com/angristan/wireguard-install

I personally use this script to setup a wireguard server. Doing it by hand is totally possible but this makes things a bit easier.

I do the same with Amazon and haven't had any issues. I run wireguard on an Amazon instance with the following script: https://github.com/angristan/wireguard-install
