Ask HN: The government of my country blocked VPN access. What should I use?

I lived in China for a while and there were several waves of VPN blocks. Also very few VPN services even try to actively support VPN-blocking nations anymore. Any commercial offering will be blocked eventually.

What I settled on for decent reliability and speeds was a free-tier EC2 hosted in an international region. I then setup a SOCKS5 server and connected my devices to it. You mentioned Cloudflare so whatever their VM service is might also work.

It's very low profile as it's just your traffic and the state can't easily differentiate your host from the millions of others in that cloud region.

LPT for surviving the unfree internet: GitHub won't be blocked and you'll find all the resources and downloads you need for this method and others posted by Chinese engineers.

Edit: If you're worried about being too identifiable because of your static IP, well it's just a computer, you can use a VPN on there too if you want to!

When I worked in China (not for long periods but frequently enough that the Great Firewall became an irritant) I hosted an OpenVPN server on port 443 and/or port 22 of a server I owned. That worked sufficiently well most of the time.

This doesn't work anymore; the GFW no longer detects VPN connections by port but instead by performing deep packet inspection to characterize the type of traffic going over every connection. Using this technique in combination with some advanced ML systems, they're able to detect any encrypted VPN connection and cut it off; it's basically not possible to run any kind of outbound VPN connection (even to private servers) from inside of China anymore, and it's usually not even possible to _tunnel_ a VPN connection through some other protocol because the GFW now detects that too.

Stepping back and looking at it from a purely technical perspective, it's actually insanely impressive.

Here's a USENIX paper from a few years ago on how it is done: https://gfw.report/publications/usenixsecurity23/en/

So there's a disconnect between what you're saying and what others and myself have experienced in China even recently. You appear to be saying that it's not possible to use a VPN to bypass the GFW, but I apologise if I have misunderstood.

The comments have multiple examples of people successfully bypassing the firewall. I personally just used Mullvad with wireguard + obfuscation (possibly also DAITA) and it just worked. No issues whatsoever.
