Acid Birt

Hello I'm a clueless student that loves working with servers but I am broke. So I was searching for a QBittorrent VPN but PIA and Airvpn wich both require you to pay money ( Currently I am saving up to buy Unraid because I am using the Trial) Anybody know a free option , or better a VPN wich I can host myself and route it trough there? I really need this because I am pretty sure my ISP is throttling me. Also if this is a question that is answered already my excuses but I could not find anything. Thanks in advance!
