为什么这段代码不起作用（简单代理） [英] Why this code doesnt work (simple proxy)
问题描述
我使用了以下代码示例，但它不起作用。我不知道什么是错的。它没有做任何事情，我需要它将端口1205上传入的通信重新发送到另一个端口，即。 1203在同一台机器上。我真的很感激任何帮助。谢谢你 namespace
Hi, namespace
I have used following code example but it doesnt work. I dont know whats wrong. It does nothing, I would need it to resend communication incoming on port 1205 to another port,i.e. 1203 on the same machine. I would be really grateful for any help.Thank you

推荐答案
您好，
确保没有其他东西正在侦听端口80，就像IIS一样。在我的本地机器上停止IIS后，我能够使用它。

Hi,
Make sure nothing else is listening on port 80, like IIS. I was able to get this to work after stopping IIS on my local machine.
