Intra VS redsocks

Other than that, Rethink is a proper network monitor and a (tcp/udp) firewall; while DDG is a browser bundling in DNS-based protection, from what I can tell. DDG is based on NetGuard, but they don't license that tech as FOSS but only under source-available license. Rethink is fully FOSS, and it was initially a fork on Intra, but it has diverged very much from Intra that it is no where near similar to its predecessor, anymore.

Haven’t used Intra before but it looks like it uses Google’s Firebase analytics (https://github.com/Jigsaw-Code/Intra/blob/master/Android/app/src/main/java/app/intra/sys/firebase/AnalyticsWrapper.java) (no surprise though since Intra is by Google (Jigsaw team)).

I used redsocks (https://github.com/darkk/redsocks) for that, but with completely external proxies. However, this solution requires configuring iptables rules inside the container, which may be unsuitable for your usecase

I don't think you can generally expect all processes to transparently use a SOCKS proxy? You might be able to finagle a custom vpn around it, I suppose. But AFAIK SOCKS isn't 100% transparent at the IP layer allowing all protocols to transparently layer on top?

I guess SOCKS5 handles tcp and udp - so you might get away with redsocks (which explicitly recommends against using with TOR):

See also transocks (SOCKS4 tcp only): https://transocks.sourceforge.net

And transocks (in go) https://github.com/cybozu-go/transocks

Who nowadays might be interested in a yet another transparent SOCKS protocol redirector/wrapper if we, besides many other projects, already have Redsocks for firewall- and tsocks for LD_PRELOAD- based traffic forwarding?

Second this. I haven't tried proxychains. iptables with redsocks[1] for redirection works pretty nice.
