I was wondering, lets say i make a rule which allow connections to the port 52000 when programA.exe is running. While this program is runnig, will 'everything else' be able to access/use that port or is it only programA.exe? i'm asking because i did a probe of a specific port while a program of mine was using that port, and it was shown as open. That kinda ruins the idea of the whole firewall concept, unless it still protects the port from connections 'outside' this app ofcourse. Maybe worth to mention, this specific 'allow tcp/udp from port xxx' is placed in the top of the rules list...dunno if it has something to say.
