In thousands of Linux and BSD distributions, there is no single system desktop environment that proxies all traffic, I’m in a country where the internet is very blocked, and Upgrad or downloading software is a hassle, github gitlab Ping over time 300ms. [TUN](https://docs.kernel.org/networking/tuntap.html) Any network protocol uses the proxy, proxy default [TUN Mode](https://docs.kernel.org/networking/tuntap.html) can solve this problem, the entire system traffic through TUN Mode I can TOR i2p proxy to make myself more anonymous https://docs.kernel.org/networking/tuntap.html
It's entirely unclear to me what you are asking for and how that relates to KDE. Can you please explain that more?

settings ⇒ Proxy, choose manual proxy and set the ip Let http-proxy, socks-proxy proxy all network traffic of the system, this is the linux kernel's [Universal TUN/TAP device driver](https://docs.kernel.org/networking/tuntap.html) Convenience, it can proxy the network traffic of any software of any protocol of the system As we all know, KDE's system proxy is very difficult to use, many programs will not take the system proxy Therefore, we need to set the proxy manually in various places to make sure the program can read the proxy configuration correctly
