Please document how to use FWRDING and UDP Associate #50

Closed Retkid closed 2 weeks ago

  1. You've extended socks5 but never mentioned how to use it. I've been reading the code, but its very labyrinthine and confusing. But, the FWRD command type is 0x5.
  2. The server sends you an IP and Port, like the UDP Associate, but unlike UDP associate, its the port you requested in the FWRD??? E.g 127.0.0.1 12345
  3. If you try and TCP connect to that port, its closed. If you try and send a forward command as defined by socks5, over tcp on the original connection, it does nothing and responds with nothing. How am I supposed to use it?

Also, I cannot get UDP associate to work at all, and I'm unsure if this is your fault.

Extended UDP FWD is a method of forwarding UDP packets in a TCP connection. The address in the response message of this command is not used, and the forwarding is on the original TCP connection of current session. The clients compatible with this command are hev-socks5-tunnel and hev-socks5-tproxy, and they need to be configured with udp: tcp.

While I do think you might have feel you "fixed" this issue, pointing to 2 projects which also don't have your packet structure documented isn't a solution. Not everything perhaps wants to work within your ecosystem, and maybe I wanna extend it, or add support for this because I like the feature.
