Hijust for my understanding. Why is such an app needed? This is issue should be solved by router ACLs or even better a firewall.

I would ask the same. To me it looks like looking in wring direction.

The only thing I can think of is to have your app open port 80 and keep it open. Of course, your app has to be open BEFORE the browser in order for that to work. Your best bet is to simply turn on the Windows firewall and block outbound traffic on the ports typically used by internet capable apps. I'm not sure (because I don't use it), but the Windows firewall may also be able to block specified apps.

Opening port 80 would not work at all. Port 80 is at destination point not at source. But as you said, a firewall would do the job. and only a firewall
