Do not accept connection locally before connection with remote is established, is it possible?

[janedoe-lab]

Currently, when proxied application makes a connection, it immediately succeeds as if port is always open. This works very differently from proxychains, which waits to establish connection with the remote. It is a subtle difference, but it breaks software that needs to check if port is truly open.

I am not familiar with LWIP and usage of namespaces - I couldn't identify area where connection is "accepted" locally.

Do you think it is even possible with the current architecture? And if yes, perhaps could point me to where to look at relevant pieces of the code, so I could try my hand at tweaking it?

Hi,

Thanks for your advice. It's not hard to implement. I've done on it.

Could you have a try on this?

It works awesomely! I've submitted small PR #5 just to clean up error messages.

Thank you so much!
