I recently created a reverse connection shell in C#. I tested it with some computers and I noticed that some computers connected back correctly and I established connection with them but another computer running Windows 7 doesn't seem to work or establish a connection back to me.
I was using port 3001 as a communication port, and I was trying to establish a reverse connection. Any help why this computer doesn't work ? Is using port 80 or 443 as a communication port will help or It is the same as the connectiion is reverse ! In other words, Is it really better to use port 80 or 443 for outgoing traffic in a reverse connection ?
