Authorization on a proxy server through a router?

Question

Computer networks

Hello, I have a working network with authorization through a proxy (login and password). tell me which router I should install so that it logs in to the proxy server, and gives, so to speak, clean Internet without authorization. Or what firmware of routers support it?

Answer 1

DD-WRT, need to pee a little in the CLI

Answer 2

out of the box - none, because the router routes traffic at the network level, and the proxy, depending on the type, works at the application or presentation level, and it is basically impossible to let arbitrary network traffic through the proxy. In general, for TCP protocols, this task is solvable, but not so trivial. You can put a local transparent redirector on the router (for example, 3proxy with the TransparentPlugin plugin), route TCP traffic into it, and use it to route traffic through the parent proxy with authorization. But such a scheme will not pull a high load, because routers are not designed for local traffic processing and are usually made on rather weak hardware, they effectively process only passing traffic, because while the main flow of traffic goes past the processor.
