通过互联网直接连接到计算机..? [英] direct connection to computer over internet..?

问题描述

嗨
我想将通过Internet运行程序的用户彼此连接，并且不需要用户进行特殊的端口设置.我希望用户直接连接，而不是通过服务器.服务器可以根据需要断开连接，但是会话不应通过服务器.

如果我想直接连接，那么可以避免端口转发吗?如果是，怎么办?

Hi
I want to connect users that are running a program over the internet with eachother, and no special port setting by the user will be required. I want the users connected directly, not through a server. a server can hand the connection off if needed, but the session should not pass through the server.

If I want to connect directly then is it possible to avoid port forwarding ? if yes How?

推荐答案

没有像您所描述的那样与另一台计算机直接连接"的事情.服务器必须侦听一个端口，该端口可以接受传入的客户端请求.如果服务器前面有防火墙，则将需要某种类型的端口转发.听起来好像您真的不太了解TCP/IP通信的工作原理.

There is no such thing as a "direct connection" to another computer as you desribed it. There must be a port that a server is listening to that accepts incoming client requests. If you have a firewall in front of your server, some kind of port forwarding is going to be required. It sounds as though you really don''t have a good idea of how TCP/IP communication works.
