Mullvad to China: Block This. We Dare You

Yep, agree, it does work and with multi hop also allows your own country of origin only when it’s through Sweden also.

Eh they'll adapt. Simply using QUIC won't be enough. The cadence of VPN traffic can and will be detected. It might take them a while to catch up that's all. Best thing is to just not go to China, and if you do need to, to use your mobile internet or work VPN.

I read about Russian VPN situation from time to time, and any simple obfuscation attempts fail now. They had to invent more protocols, like TrustTunnel. Previous popular protocol was VLESS, and it used TCP. TrustTunnel uses QUIC and possibly UDP, looks like similar to what is described in the article. So, I guess, Mullvad might work in DPI-heavy environments, but I wouldn't be as sure as author is. All I know it is becomes harder and harder to obfuscate VPN traffic in the countries with good hackers who work for the government.

Why would China use HTTP/3?

mullvad is the only vpn worth using

> Mullvad took their VPN traffic and wrapped it in QUIC obfuscation. To the CCP's omniscient routers, it doesn't look like a VPN trying to tunnel out. It just looks like boring, encrypted HTTPS web traffic. Ignoring that this article is shamelessly LLM-generated, I did not actually know Mullvad had QUIC obfuscation, so this is a cool fun fact. > Connect the dots here. The only way the Chinese government can block Mullvad now is to block all HTTP/3 traffic. If they do that, they instantly nuke their own banking sector, e-commerce platforms, and state infrastructure. No they don't. The amount of work it takes to have a HTTP/3 web server means those sectors probably don't even have it yet. Even if they did, I wouldn't expect HTTP/3 to be the only way to access anything , not even a decade from now. Even HTTP/2 was awful to get working when it was new, and I haven't heard of even a single server not accepting HTTP/1.1; you are still more likely to encounter servers not even supporting HTTP/2 yet, let alone HTTP/3.

Clickbait and aggressive title, shallow article. I read it and not worth clicking.

Chinese people have been developing similar obfuscation protocols and playing a cat-and-mouse game for years, and most of them are "open source" (in quotes because lots of them have to be somewhat hidden because the Chinese gov threatens the devs). Props to Mullvad, but it's not like they're unique in this regard.

AI slop writing.

Last time I checked, they don't really care about vpns there. They just filter internet traffic to A) encourage home grown alternatives to e.g. Google, Facebook and B) Stop Grandma from reading Radio Free Asia

1. This is obvious AI slop 2. China can just ban the Mullvad IP ranges. They don't change that often
