[Feature] Do not accept connection locally before connection with remote is established

[janedoe-lab]

Description

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.

Is it possible with current tun2socks architecture to implement feature (or is this a bug?) where tun2socks would first try to connect to the port, and only if it succeeds, report success on the client side?

Is this feature related to a specific bug?
