GitHub - rssnsj/socksnat: SOCKS 5 transparent proxy service
NAT mechanism of IP packet to SOCKS protocol transf orming. Description: A small but useful project. I name it "SOCKS NAT". It's like 'redsocks'. The goal is to convert a SOCKS proxy service to an IP gateway which is more compatible, e.g., some mobile devices like iPhone do not support SOCKS proxy, so an IP gateway is better and convenient for them. The first available version has been finished. It

TCP ex Machina
What is congestion control? On the Internet, most of the intelligence lies in the endpoint computers, not inside the network. One of the endpoints' responsibilities is to fairly share the network's limited resources among themselves. For example, in a house with a 10 Mbps connection to the Internet, with two users trying to upload a video to YouTube at the same time, it's usually the users' comput
