AntiZapret-V2Ray VS sslh

For what it’s worth as well, there are other solutions than whole-network VPNs and such. Personally, I chose to generate a domain list for V2Ray from the Russian government’s blocklist when I lived there [1].

I prefer to do that typically because it avoids the pain of the ever-growing whitelists and it allows me to keep the traffic encrypted in case someone does actually figure out that you’ve bypassed DPI. And if you use something like V2Ray or ShadowSocks, they’ll disguise the traffic much better than something like OpenVPN typically would, making it less obvious to anyone monitoring that you’re using a proxy in the first place.

There’s a load of references and pre-generated lists for different needs if anyone else is interested in doing something similar [2].

That already has a (brutal) solution now - sslh https://www.rutschle.net/tech/sslh/README.html - the current version is more sophisticated, but it was originally just a perl script that would send the connection to sshd or the https web server, based on regex matching on an initial string (and I probably timing out and going to sshd if it didn't see one? Something like that, I haven't dug out the old code to check.)

Maybe something like https://github.com/yrutschle/sslh would work? Although it will probably break mobile client as well.

I think you're looking for sslh.

However, there is a hacky tool that should fit your use case, you could try that: https://www.rutschle.net/tech/sslh/README.html

I haven’t tried it but have a look here. TBH I didn’t even know sslh supported UDP!
