I have an app, a replica of a shooter game in Android. It is just for experimental use only, me and my friends are testing it. I need to block all TCP connections so I can test my security.
But its servers change IP addresses of the domain, so no matter how many ways I use to block the domain, user still get connection with the server.
Is there a way to only block TCP connection for an app? But only TCP connection, because my playing server is UDP server.
Can I block all incoming TCP connections as well?
