Nice work, these types of tools are invaluable and there are well-supported paid options, but not that many OSS projects. There is another project called fast reverse proxy (frp) that has been around for a while, it's open source, however some users are concerned with the country of origin. Never the less, it's probably more mature and well-tested at this point.<p><a href="https://github.com/fatedier/frp">https://github.com/fatedier/frp</a>
