The first project (swgp-go) which makes traffic resemble random noise, can be trivially blocked. The DPI calculates the ratio between number of 0 and 1 bits, and if their amount is approximately equal, and traffic doesn't match allowed protocol (like HTTPS), then the connection is blocked.
If you don't want to stand out you should use steganography and masquerade as a legitimate and popular protocol. It seems that MASQUE does exactly this.
- kevincox 2y agoHTTP/3 is QUIC. So you can tunnel whatever you want over a connection that is not reliably distinguishable from HTTPS. (You can do heuristics based on packet sizes and timings)
- ignoramous 2y agoMuch more effective, really. I built one such self-hostable proxy on Cloudflare Workers & Deno Deploy: https://github.com/serverless-proxy/serverless-proxy https://github.com/serverless-proxy/serverless-proxy (http-tunneling only works on Deno Deploy, and requires an enterprise plan on Cloudflare but tunneling with websockets works on the free plan, as well).
- codedokode 2y agoMy observation is that if you use a tunnel not for VPN (which typically uses one long connection) but for a SOCKS proxy (which requires a new connection for every proxied connection) then the timings strongly resemble real HTTPS timings.
