Over the years I've noticed random firewall rules automatically show up in routers.
E.g. some kid will come and start using a computer in the office and all of a sudden there is something like cheat-engine firewall rules added to the actual router. I believe that Skype used to do the same. I've seen various applications automatically make changes to the router.
Does anyone know how this is done?
The reason why I want it: I've made a demo application that is downloadable which is basically a launcher to a cloud hosted filemaker database. I've been running into firewall troubles with some people wanting to use the demo and it would be nice if my installer could auto add the filemaker firewall rule.
