Suppose I have a computer at home I want to be able to access from anywhere in the world. I can pay a host, a vpn, something like aws or resort to proprietary solutions like teamviwer or similar options. I don't want to resort to any of these alternatives. I want something that is both open source and that I don't have to pay for. The only solution I could find was tor (or maybe i2p) which has its own downsides: high latency, low bandwidth and requires special tools. Is there any possibility I'm not considering?
