GoodbyeDPI VS dnscrypt-proxy

Right now, it is accessible only through VPN. Even programs like DPI blocker are not helping

As in you cant access those sites (you got redirected to the ISP site)? Try changing your dns (make sure to clear your dns cache too) and try using goodbyedpi. Recently my country start enforcing isp to block piracy sites along with other sites (porn, reddit, etc) but since their method is just to use dpi, i could just use goodbyedpi to bypass it.

Russian internet censorship is very simple. They don't seem to be using DPI to target VPN protocols at all, instead trying to block IPs/subnets of known commercial VPN providers. Blocking IPs, subnets, and domains is the primary operating mode of Roskomnadzor.

There allegedly is DPI, but it only comes into play as an extra measure against things like domain fronting, proxies, and plaintext HTTP. It'd look at the SNI and inject a RST packet to drop the connection. As it does not even try to implement TCP, analyzing each IP packet in isolation, there are various interesting utilities[1] that mess with it by, for example, splitting the TLS ClientHello into two TCP packets in the middle of the domain name.

Also, try this tool, you'll find that unblocks most content for you. Good luck!

That can be done at DNS level in dnscrypt-proxy: https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Filters#time...

There is more than one way to do this but I have decided to use dnscrypt-proxy. We will not be using dnscrypt for the dnscrypt protocol though you could elect to use that as the underlying DNS protocol. dnscrypt-proxy lets's us use a SOCKS5 proxy through which the DNS queries will be sent. We will use a Tor SOCKS5 proxy here. You can choose which protocols should be enabled and which ones should be disabled. There are two points:

I tried installing the RPM from the Fedora repos but it's out-of-date and there were no instructions on how to get it operational, so I went with the manual approach as per their wiki: https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Installation-linux

This is awesome, thanks -- going to look into that now. I found SmartDNS interesting and thought I would share it, it's pretty simple to setup. I can see why it's Chinese focused, they have "interesting" internet access over there :-).

I have been looking into DNS quite a bit lately (Unbound, etc), as DNS lookup performance has been pretty subpar lately. I'm in Perth, Australia, and we're pretty remote so our latency is meh at best, and Cloudflare performance has been all over the shop lately, I think they're having issues in WA). DNS can also cause really routing issues here sometimes as we get better latency to Singapore than Sydney, so we might get shunted off to SG.

I've also been using dnscrypt-proxy2 (https://github.com/DNSCrypt/dnscrypt-proxy) for a while, but the above issues with Cloudflares DNS is what triggered me to look into other options.

I use a min-cache-ttl of 15 minutes, which seems to work well.

Thank you for sharing this tip about, looking into this now :).

Sure. I run dnscrypt_proxy behind a pihole. https://github.com/DNSCrypt/dnscrypt-proxy
