As part of a security research, I need to make my WiFi open, and to inspect the traffic of the ones who connect to it. Additionally, I need to be able to change the content of the webpages they see, and generally to act as a man in the middle.
Do you know relevant tools or tools that already do this?
Can someone give me some guidelines and relevant references?
Which technical problems I might face during the development process?
Which platforms/languages are recommended for such a project?
